PRODUCT INTRODUCTION: The EMC-16 is quite simple to use and

operate, but underneath that simplicity lies a significant level of

sophistication. To get the safest and most effective use of this instrument,

it is important that the user fully understand the product. Please read and

understand this entire manual and know the principles and practices of

safe diving before using this device. If you are using the EMC-16 with

Nitrox, the diver specifically acknowledges that he has been adequately

and thoroughly trained and certified to engage in Nitrox diving by a

professional, competent, recognized training agency.

This Manual is divided into the following Sections:

SIDE CONTACTS:

The Contacts are used to let the user command the unit to do a number of

functions, communicate with a PC for extracting information or configuring

the unit, and determining water conductivity. When Contacts 1 & 2 are

shorted, the EMC-16 can detect the difference between wet fingers, metal

objects, fresh water, salt water, and a PC interface probe.

TURNING ON THE EMC-16:Although the EMC-16 automatically turns on

when it is submerged in water, it is STRONGLY recommended that the

unit be manually powered up by wetting two fingers and simultaneously

touching Contacts 1 and 2 for two seconds. This allows the diver to

ensure that the unit is operating correctly and has adequate battery

capacity prior to entry. Once activated, the unit will remain on for 60

minutes. If a dive is not initiated within this 60 minutes, the EMC-16

automatically shuts off. Notice that when Contacts 1 & 2 are first bridged,

a short beep is issued which indicates that the unit is recognizing the

touch. Every time Contacts 1 & 2 are bridged with wet fingers, the unit will

stay on for one full hour.

The EMC-16 will not turn on if the altitude is greater than 16,000 feet or if

the battery voltage is less than 2.0 volts, or a fault is detected during the

self-test.

As the EMC-16 first recognizes a turn-on command, it begins a

“Diagnostic” function where many aspects of the system will be exercised

and tested. This procedure takes about three seconds and an audible

beep is issued each second as certain tests are successfully completed.

During this time, all of the segments in the display are turned on so that

their operability can be confirmed by the user. Should a test indicate a

malfunction or marginal test, the unit will turn back off again. The user

should ensure that all of the display segments are on and operating

correctly.

TURNING OFF THE EMC-16:After the Post Dive Interval following a

dive, the EMC-16 will remain on for one hour before automatically entering

its "Sleep Mode". During the Sleep Mode, all calculations continue but the

display is off. This is a power saving feature of the EMC-16. The unit will

continue calculating Surface Interval, nitrogen off gassing as required, and

any changes in altitude as it affects Nitrogen Loading. The current Surface

Interval and PreDive Predictions can be viewed by reactivating the unit

MAIN EMC-16 OPERATING MODES:

•Surface Interval (No Nitrogen Residual)

•Surface Interval (With Nitrogen Residual)

•Dive Mode (Normal No Deco)

•Decompression Mode

•Post Dive Interval

•Touch Programming

SURFACE INTERVAL:

After completion of the Self-Diagnostic mode or after the Post Dive Interval

following a dive, the EMC-16 enters the Surface Interval. This period has

two screens, a Primary and an Alternate. To switch to the Alternate

Screen just tap once firmly on the face of the unit. The Primary Screen

displays, if applicable; current Surface Time, the previous dive’s Maximum

Depth, the previous dive’s Bottom Time, Dive of Day number, current Time

to Fly, Altitude and Temperature. The Alternate Screen displays the

Current FO2 (normal Blend) oxygen percentage, current calculated CNS

and OTU values, and current battery voltage. Figure 2 shows the display

with no residual Nitrogen (a clean Dive). Figure 5 shows the display with

residual Nitrogen (a repetitive dive). Figure 3 shows the alternate screen

without residual Nitrogen, figure 6 with.

“Surface Time” starts at zero after a dive and begins counting minutes. If

the computer shuts off and is turned on with Nitrogen residual left, the

Surface Time continues to count. If the computer shuts off and is turned

on with no Nitrogen residual left, the Surface Time will be zero.

The “Dive of Day” starts at zero and increments after each dive regardless

of the calendar day. When there is no remaining Nitrogen residual, the

Dive of Day is set to zero and the computer is referred to as a ‘clean’

system.

“Time to Fly” is displayed as the number of hours remaining until the

nitrogen residual reaches zero plus a twelve-hour safety factor. Flying is

not recommended until “Time to Fly” reaches zero.

“Barometric Altitude” is indicated in six ranges via the Ascent Rate Bar

Graph as follows (Altitude compensation is seamless up to 16,000 feet

above sea level). The six ranges are for display purposes only: The

EMC-16 actually senses and computes extremely small altitude changes

and hence, is called “Seamless”. The term “Barometric Altitude” is used

instead of just “Altitude” because the EMC-16 measures Barometric

Pressure to determine Altitude. Barometric Altitude can vary from actual

Altitude by over +/- 1000 feet! What is important to the body when diving

is “Barometric Altitude”.

0 Bars sea level to 2,500 feet

1 Bar 2,500 to 5,000 feet

2 Bars 5,000 to 7,500 feet

3 Bars 7,500 to 10,000 feet

4 Bars 10,000 to 12,500 feet

5 Bars 12,500 to 16,000 feet

DIVE MODE:

Whether in the Surface Interval, PreDive Prediction Mode, Programming

Mode or the Logbook Mode, the EMC-16 will automatically enter the Dive

Mode whenever the unit determines that it is in water deeper than five feet.

On the Primary Screen the Surface time will be replaced with the current

calculated PO2value. Maximum Depth will be replaced with current

Depth, displayed in one-foot increments. Bottom Time will begin once the

EMC-16 senses that the diver has descended below five feet and

continues until the diver has ascended above three feet. The maximum

Bottom Time displayed is 9 hours 59 minutes.

The Alternate Screen will display the current FO2value that the unit is

using in its NDC calculations, the current CNS and OTU values and the

current battery voltage. (Figure 11)

In the Dive Mode the Alternate Screen will display the current oxygen

percentage that the computer is using in the NDC calculations, therefore

after a gas switch the unit will display the Deco Gas Blend oxygen

percentage.

A Depth Alarm which can be set to warn the diver should a certain depth

be exceeded is set at 130 feet from the factory. The Depth Alarm issues

an audible alarm and the “WARNING” legend and Depth Digits will flash

on and off for five seconds. The depth alarm is disabled if in the

Decompression Mode since flashing depth digits have another meaning in

this Mode.

The maximum depth achieved on the current dive is shown as “MAX

DEPTH”. This is updated once per second.

“REMAIN TIME” (NDC) is the remaining time (in hours and minutes) that

the diver can stay at the current depth without requiring decompression. A

“Two Minute Warning” will be issued when this time reaches two minutes

or less. An audible alarm will be issued and the “WARNING” legend and

“REMAIN TIME” digits will flash. By immediately ascending to a shallower

depth, the diver may avoid a required decompression stop.

Temperature is measured for two purposes. One is to compensate the

Depth Transducer for Temperature variations. The other is to compensate

the Nitrogen algorithm for changes in Temperature that may affect the

body. Both of these purposes require that the Temperature be very slow

reacting, just like the Depth Transducer and the body. This slow-reacting

Temperature is what is displayed. For Temperature effects on the body,

the amount of compensation can be set from NORMAL to REDUCED with

the Analyst® PC software Interface (see Analyst® Section), if the diver is

using a good dry-suit in cold water. Temperature compensation starts at

75 degrees F and gets progressively more conservative as the

temperature decreases. There is no compensation above 75 degrees F.

Bottom Time will begin once the EMC-16 senses that the diver has

descended below five feet (see Training Mode) and continues until the

diver has ascended above three feet. The maximum Bottom Time

displayed is 9 hours 59 minutes.

ASCENT RATE BAR GRAPH:

The Ascent Rate bar graph and alarms are active in both the Dive Mode

and Decompression Mode. The five-segment bar graph is used to display

the diver's rate of ascent.

Via the Analyst®PC Interface, the Ascent Rate Alarms and Bar Graph can

be set to the users preferences.

The first option is a VARIABLE-BY-DEPTH Ascent Rate. When “on”, the

Ascent Rate Alarm is determined by depth. As the diver ascends to

shallow depths, the Maximum Ascent Rate is lowered. The Maximum

Ascent Rates and their associated depth are:

60 feet or deeper 60 feet per minute

60 to 30 feet feet per minute equal to the depth

Less than 30 feet 30 feet per minute

If VARIABLE-BY-DEPTH is off, the Maximum Ascent Rate Alarm and Bar

Graph is specified by the user and can be from 20 to 60 fpm, in one foot

increments.

Another selection is the bar graph itself. The two selections are either

FIXED or PROPORTIONAL.

With FIXED, each of the five bars indicates an additional 10 feet per

minute of Ascent Rate regardless of the Maximum Ascent Rate selected.

With PROPORTIONAL, each of the five bars indicates 20% (one-fifth) of

the selected Maximum Ascent Rate.

For FIXED, the maximum ascent rate is 60 feet per minute. With this

setting, no bars will illuminate if a diver is ascending at a rate less than 10

feet per minute.

If the diver has an Ascent Rate that exceeds the selected maximum, the

entire Ascent Rate Bar Graph will flash, and the audible alarm will sound

once per second, and the WARNING legend will illuminate.

The sensitivity or responsiveness of the Ascent Rate may be selected via

the Analyst®, eight different levels of sensitivity are available.

NOTE: Customizing the Ascent Rate and Ascent Rate Bar Graph are

among many of the additional programmable features available when

using the Analyst®PC Interface. Available features are described in the

section “USER CONFIGURABLE OPTIONS”.

As shipped from the factory, the Ascent Rate is set for VARIABLE-BY-

DEPTH AND PROPORTIONAL.

DECOMPRESSION MODE:

Should a no-decompression limit be overstayed, the EMC-16 will enter the

Decompression Mode. In this mode, the Ceiling digits will display the

depth at which the diver must stop and not ascend above during final

ascent. The “TEMP” legend and two digits will be replaced with the “CEIL”

legend and two digits. The Ceiling will start at 10 feet and increase in ten-

foot increments as the diver remains at a relatively deep depth.

The Remaining No-decompression Time and “NDC” legend will be

replaced with Decompression Time and “DEC” legend (Figure 16d). Both

STOP time and TOTAL time are displayed in the upper left hand three

digits of the screen in hours and minutes. STOP and TOTAL time will

alternate at the rate of once every two seconds. In this way, the diver can

view the time to spend at a particular STOP depth, and the TOTAL time it

will take to complete all STOPS. Clearly, the larger of the two alternating

numbers is the Total Decompression Time of all stops, and the smaller of

the two numbers is the time required at the current stop. At the ten foot

stop, the TOTAL and STOP times may be the same and therefore appear

to not alternate.

When at a specific stop, the required decompression time at that stop is as

shown, and will appear to count down as it is recomputed every second,

based on the divers exact current depth. The Decompression times (both

Stop and Total) are accurate only if the diver’s depth is exactly the same

as the required Ceiling. However, it is not necessary to be precisely at

that specified Ceiling. Appropriate In-gassing or Out-gassing will be

computed regardless of the diver’s current depth.

A small margin shallower than the Ceiling also exists. Should a Ceiling be

‘violated’ (diver is shallower than Ceiling), the “WARNING” legend will

illuminate and flash along with the Depth and Ceiling digits. An Audible

alarm will sound once every two seconds. This warning will continue until

the Depth has been corrected. Out-gassing will continue even though the

diver is shallower than the Ceiling. There is no ‘Gauge’ mode or ‘Lockout’

on the EMC-16.

If the diver surfaces before satisfying his decompression obligation, the

EMC-16 will continue to give out-gassing credit as if it were in a dive, but

at a depth of zero feet and will satisfy the decompression time

requirements of the required stops using an FO2of 21%. The unit will

continue to log data and perform as if actually in a dive. When the

decompression obligation is finally satisfied, the ten-minute “PostDive

Interval” will begin.

Several seemingly ambiguous situations may occur with the Deco

Forecast ‘enabled’, they are:

•Satisfying Deco Stops during ascent.

•The Deco Gas Switch may occur early or late.

•Forecast Deco Stop time & depths may switch up/down/up/down as

the diver ascends due to the in-gassing and out-gassing of the

different ‘controlling’ tissue group.

NOTE: COCHRAN does not intend for this instrument to be used for

deliberate Decompression diving.

POST DIVE INTERVAL:

During the first ten minutes (or up to thirty minutes if the unit is in the

Training Mode) after a dive, the EMC-16 is in the Post Dive Interval. The

flashing "SURF" legend and a Surface Time of less than ten minutes (or up

to thirty if the unit is in the Training Mode) indicate this. Should another

dive be commenced before the completion of the Post Dive Interval, that

dive will be considered an extension of the previous dive. In this case,

Bottom Time will NOT include the time spent on the surface in this Post

Dive Interval. However, when reviewing the profile with the Analyst®, the

time spent on the surface in this period will be shown. In the case were the

unit has performed a gas switch; while in the Post Dive Interval the

Alternate Screen will display the Oxygen percentage of the Deco Gas

Blend and if the diver re-enters the Dive mode the unit will perform its’

calculations based on the Deco Gas Blend Oxygen percentage until the

diver descends below the Gas switch Depth. Below this depth the unit will

revert to the Normal Gas Blend for the NDC calculations.

CONFINED WATER PROTOCOL (Training Mode): The EMC-16 is one of

the first dive computers to offer an operating mode designed to record and

store data from training dives. That is, dives performed in shallow water

environments (swimming pools, shallow lakes, lagoons, etc.) or calm open

water environments that have less than 1-foot seas. In the Training Mode,

the EMC-16 enters the Dive Mode at a depth of 2 feet instead of 5 feet and

will exit the Dive Mode at 1 foot instead of 3 feet. Also the Post Dive

Surface Interval may be extended, via the Analyst®from10 minutes up to a

maximum of 30 minutes in 1-minute increments after which the dive data is

stored in the computer's memory. These changes permit the Instructor to

record the complete training session, including in-water surface periods, as

a single dive. The Training Mode can only be enabled/disabled via the

Professional Edition of the Analyst®PC Interface.

TACLITE™: The EMC-16 is equipped with the TACLITE™ tactical low-

light fiber-optic backlighted display. The standard TACLITE™ color is night

vision safe red, but it is also available in yellow for those individuals who

have vision difficulties with the color red. The TACLITE™ can be activated

on demand. To turn the TACLITE™ on, tap the face of the EMC-16 and

the TACLITE™ will turn on for the preprogrammed number of seconds (1

to 98), then turn off. By tapping the face again the TACLITE™ will turn on

again. In this fashion the TACLITE™ can be kept on for as long as

wanted. If 0 is entered, the TACLITE™ will never turn on. If 99 is entered,

the TACLITE™ will stay on continuously and only turn off when the EMC-

16 does. The number of seconds that the TACLITE™ stays on can be set

via the Programming Mode or via the Analyst®PC Interface, factory setting

is 10 seconds. The TACLITE™ will turn off when the EMC-16 turns off. If

the batteries get too low, the TACLITE™ will turn off and cannot be turned

back on until fresh batteries are installed.

CLOCK MODE: The Clock operating mode of the EMC-16 is NOT

enabled when shipped from the factory. It can be enabled via the Analyst®

P.C. Interface or at an Authorized Cochran Dealer.

TOUCH PROGRAMMING MODE: Can only be accessed when the unit is

in the Surface Interval and allows the user to view or program into the dive

computer:

•Setting Clock and Alarm Time

•The PreDive Prediction Mode

•Displaying Mode, mode value, CNS, OTU & battery voltage

•A Maximum Depth Alarm

•An Added degree of Conservatism from 0 to 50%

•Setting oxygen percentage of blend 1 in the Constant FO2Mode

•Setting the Deco FO2oxygen percentage

•Setting the Deco Bottom Time Benchmark

•Setting the Deco Depth Benchmark

•Programming the On Time for the TACLITE™

•Access the Logbook Mode

While all EMC-16 configurations share certain programming features

others are dependent upon the specific configuration of the unit.

Refer to the appropriate manual section for the relevant programming

menu items.

TOUCH PROGRAMMING - CLOCK: When the EMC-16 is placed into the

Clock mode it will display the time of day in a 24 hour day format. The

clock will continue to run when the EMC-16 is in the Dive Computer Mode.

The EMC-16 can be placed into the Clock Mode from the Dive Computer

Mode when the unit is in the Normal Surface Interval, while the unit is in

Clock Mode the Dive Computer will be in the “Sleep” mode.

The Clock Mode can be selected with or without an Alarm. If the Alarm

option is selected the unit will display the alarm set time as well as the

current time.

When the alarm time is displayed the alarm is activated and at the

programmed time the alarm will sound once every 24 hours. When the

alarm is activated the unit will issue a medley of all the audible warning

tones that the EMC-16 utilizes and the TACLITE™ will flash for one

minute, this audible alarm can not be turned off, it will sound for the full

one minute period.

NOTE: This Time of Day clock is the same clock that is used to time

stamp dives. Modifying the Time of Day clock will effect the Local

Time as viewed via the Analyst®. The Date portion of the Local Time

clock must be changed via the Analyst®.

CLOCK PROGRAMMING PROCEDURE:

Contacts 1, 2, & 3 are for programming sequences.

To begin the programming sequence:

1. Turn the unit on;

2. Using a coin or other conductive metal object, briefly bridge Contacts

1 and 2 until a short beep is heard and the CLoCk Menu is seen on

the display.

3. To enter the Clock submenu, bridge Contacts 1 & 2 with wetted

fingers. This will cause the unit to display the CLoCk Alarm selection

– On or OFF. To Toggle the selection, bridge contacts 1&2 with

wetted fingers.

4. Using a coin or other conductive metal object, bridge Contacts 1 & 2

to access the CLoCk Time or Alarm setting screen.

5. Shorting Contacts 1 & 2 with a coin will cause the first digit of the

minutes to flash.

6. Shorting Contacts 2 & 3 with a coin will increment the numeric value;

continue until the required value is displayed. A confirmation beep

will sound with each increment.

7. Next using wetted finger, bridge Contacts 1 & 2 to select the next

digit, once selected the digit will flash to identify that it is being

programmed. Bridge Contacts 2 & 3 till the desired value is

displayed.

8. To select Hours short Contacts 1 & 2 with a coin, increment as in step

6 and 7.

9. Repeat step 5 through 7 until all digits have been programmed.

10. To save the changes that have been made bridge Contact 1 & 2 with

a coin or other conductive metal object. Once the next programming

option is displayed the changes have been saved.

To exit the Clock Mode Bridge contacts 1 & 2 with wetted fingers and the

computer will return to the Dive Computer Mode’s Surface Display.

NOTE: Ensure that the EMC-16 is in the Dive Computer Mode before

commencing a dive.

Figures 40, 41a, 41b, 42 and 43 show how the Clock display screens

appear.

NOTE: Once the EMC-16 is placed in Clock Mode the unit will remain

in that mode until exited by the diver.

TOUCH PROGRAMMING MODE:

NOTE: To enable the Programming Mode, the EMC-16 must be on the

Surface and not in the Post Dive Interval.

NOTE: All audible and visual alarms are suspended while the EMC-16

is in the Programming Mode. Upon exiting the Programming

Mode all alarms are reactivated.

NOTE: Once a value has been changed and the next menu option

selected, the new value is stored.

NOTE: It is strongly recommended that the Programming Mode is

activated again and a complete review of what was stored is

accomplished.

NOTE: If the EMC-16 is left in the Programming mode for five minutes

without the contacts being touched, the unit will automatically

exit the Programming Mode and return to the Surface Interval.

Once this occurs the EMC-16 will retain the modified

programmed settings that have been stored. Options that

have not been modified will retain their previous settings.

TOUCH PROGRAMMING MODE - PROCEDURE:

Contacts 1, 2, & 3 are for programming sequences.

To begin the programming sequence:

1. Analyze the gas blend(s) using a calibrated Oxygen Analyzer.

2. Turn the unit on.

3. Using a coin or other conductive metal object, briefly bridge Contacts 1

and 2 until a short beep is heard and the Programming Menu is seen

on the display. The menu options depend on whether the unit is

activated for the Clock, and the number of Gas Blends. The Menu

options are displayed in sequence, incrementing to the next selection

each time that Contacts 1 & 2 are bridged with a coin. The program

option is displayed on the upper row of the display. The current setting

for this option is displayed in the lower right of the display.

4. To reprogram the displayed menu values, bridge Contacts 1 & 2 with

wetted fingers. This will cause the current setting to flash or in the

case of multi-digit numbers, the least significant digit will flash. The

clock will toggle between on and off.

5. Using a coin or other conductive metal object, bridge Contacts 2 & 3 to

increment the numeric value. A confirmation beep will sound with

each increment.

6. Next using wetted finger, bridge Contacts 1 & 2 to select the next digit,

once selected the digit will flash to identify that it is being programmed.

Bridge Contacts 2 & 3 till the desired value is displayed.

7. Repeat step 5 until all digits have been programmed.

8. To save the changes that have been made bridge Contact 1 & 2 with a

coin or other conductive metal object. Once the next programming

option is displayed the changes have been saved.

All programming sequences use the same routine of using Contacts 1 and

2 to SELECT the next programming sequence and Contacts 2 and 3 to

INCREMENT the specified value.

TOUCH PROGRAMMING - PREDIVE PREDICTION:

PreDive Prediction is accessed via the Touch Contact Programming

Menu. This enables the diver to view the PreDive Prediction information at

the touch of the Contacts. During the PreDive Prediction Mode, the unit

will compute and display the maximum safe time and the calculated PO2

value at that depth. The EMC-16’s PreDive Prediction starts at 30 feet

and increases in 10 feet increments. PreDive Predictions will terminate

when the No-Decompression (NDC) time prediction reaches two minutes

or a maximum depth of 320 feet is reached. Additional Conservatism,

Residual Nitrogen, blend #1 oxygen percentage and Barometric Altitude

can affect PreDive Predictions. Once the maximum PreDive Prediction

depth has been reached the unit will return to the Surface Interval.

TOUCH PROGRAMMING - INFORMATION DISPLAY:

The InFormation display is accessed via the Programming Mode. The

information presented will depend on the configuration of the dive

computer. The information in the upper right of screen indicates the unit is

in the Constant FO2 Mode and the number of gas blends the unit is

enabled for. The following table lists the identification and the description.

Identifier Description

F0 Air only

F1 Single Blend Nitrox, 21 to 50%

F2 Two Blend Nitrox, 21 to 50% and 21 to 99.9%

Battery voltage is displayed in the lower center of the screen as a two-digit

number with a decimal point. The screen will display the current CNS,

OTU and battery voltage. The current CNS exposure level is displayed on

the lower left as a two-digit number proceeded by a lower case “c”. The

current OTU value is displayed on the lower right again as a two-digit

number but preceded by a lower case “o”. Both the CNS and OTU values

are expressed as percentages. Figure 24a displays a typical InFormation

screen for a unit that is enabled for two nitrox blends.

TOUCH PROGRAMMING - DEPTH ALARM: The Depth Alarm allows the

diver to select a maximum depth below which the diver does not wish to

descend before an alarm is issued. This depth can be set from 0 to 320

feet in one foot increments.

TOUCH PROGRAMMING - CONSERVATISM: This programming function

allows the diver to input an added degree of Conservatism into the EMC-

16’s nitrogen algorithm. Via Touch Programming the Conservatism can be

set from 0 to 50%.

TOUCH PROGRAMMING - BLEND #1:

The oxygen percentage of Blend #1 can be programmed from 21.0% to

50.0%. Once programmed the oxygen percentage will remain at the value

programmed until changed by the user.

TOUCH PROGRAMMING - BLEND #2: The oxygen percentage of Blend

#2 can be programmed from 21.0% to 99.9%. Once programmed the

oxygen percentage will remain at the value programmed until changed by

the user.

TOUCH PROGRAMMING - BLEND #2 - TIME BENCHMARK: The Blend

#2 (Deco) Time Benchmark can be programmed from 10 to 999 minutes.

Once programmed the time benchmark setting will remain at the value

programmed until changed by the user.

TOUCH PROGRAMMING - BLEND #2 - DEPTH BENCHMARK: The

Blend #2 (Deco) Depth Benchmark can be programmed from 0 to 99 feet.

Once programmed the depth benchmark setting will remain at the value

programmed until changed by the user.

TOUCH PROGRAMMING - TACLITE™: The Taclite™ dwell (on) time

can be set so that when the face on the EMC-16 is tapped the Taclite™

will stay on from 1 to 98 seconds. If the dwell time is programmed to ‘0’

the Taclite™ will never come on, if programmed to 99 the Taclite™ will be

on whenever the EMC-16 is awake.

TOUCH PROGRAMMING - LOGBOOK MODE: The Logbook of the

EMC-16 has two screens, a Primary Screen and an Alternate Screen. To

switch to the Alternate Screen just tap firmly on the face of the unit. The

Logbook is accessed via the Touch Contact Programming (see page 4).

This enables the diver to view dive statistics; the EMC-16 has the ability to

provide diving data for the most recent 1024 dives. The most recent dive

will be displayed first. To view the next dive, touch the contacts 1 & 2 with

wetted finger after pausing for a few seconds. Do not use a metal object

such as a coin or knife-blade once in the Logbook since it will cause the

unit to exit the Logbook and return to the Surface Interval.

Information contained in the Logbook will include:

Overall Dive Number Minimum NDC Time

Fastest Rate of Ascent Minimum Water Temperature

Bottom Time Surface Interval Before Dive

Maximum Depth Ending Battery Voltage

Maximum DEC Time (Deco Dive) Maximum Ceiling (Deco Dive)

It is not necessary to exit the Logbook Mode prior to initiating a dive. Once

the diver has descended below five feet, the EMC-16 will immediately

enter the Dive Mode.

NOTE: The overall Dive Number that is displayed on the Logbook Menu

screen (Figure 34) permits the diver to identify the total number of dives

made with that EMC-16. If the logbook example shown is the most recent

dive made, it can be readily identified that 235 dives have been made with

this specific unit.

Figures 35 & 37 display the Logbook of a Normal Dive.

While Figures 36 & 38 display that of a Deco Dive

WARNING INDICATIONS: Failure to observe audible and/or visual

warnings and take corrective action may result in injury or death. In

general, if the WARNING legend is flashing, some other digits should be

flashing to indicate the anomaly.

•If the diver is ascending faster than the selected maximum ascent

rate, then the top bar of the ascent bar graph will flash and the

“WARNING” legend will illuminate. The unique high to low audible

sweep alarm will continue to sound once per second until the

situation is corrected.

•If the diver descends below the user set Depth Alarm, the Depth

digits will flash. A single beep audible alarm will sound once per

second for five seconds and will repeat every two minutes. The

Depth alarm is not active in the Decompression Mode to avoid

confusion with the “Shallower Than Ceiling” alarm.

•If the battery voltage goes below 2.5 volts, the “BATT” legend will

illuminate, at 2.2 volts it will flash once per second.

•If the diver has less than two minutes of No-Decompression Time

(NDC) remaining, the “WARNING” legend will illuminate and flash

along with the Remaining NDC time digits. A single beep audible

alarm will sound once per second for five seconds and repeat every

two minutes.

•If the diver enters the Decompression Mode, a single beep audible

alarm will sound once per second for five seconds.

•During a Decompression dive, if the Depth is less than the CEILING,

the “WARNING” legend will illuminate and flash along with the Depth

and Ceiling digits. A unique high to low audible sweep alarm will

continue to sound once every two seconds until the situation is

corrected.

•If the dive computer determines that either the Depth or Temperature

sensor is malfunctioning. The “WARNING” legend will illuminate, the

computer will also issue a 5-beep two tone audible alarm once every

two minute to alert the diver to this condition. On the Appropriate

Screen the Maximum Depth will be replaced with “S-d“ or "S--" to

indicate the low-pressure transducer or “S-t” for the temperature

transducer.

•For High PO2, see “OXYGEN TOXICITY FACTORS” on page 7.

•For High CNS, see “OXYGEN TOXICITY FACTORS” on page 7.

•For High OTU, see “OXYGEN TOXICITY FACTORS” on page 7.

If an audible alarm is being issued, the computer will not switch to the

Alternate display nor will the TACLITE™ activate.

SENSOR WARNING: The EMC-16 has the capability of monitoring the

integrity of its' sensors, both the low-pressure (depth/altitude) and the

temperature. When the computer detects an error in one of the

transducers, the diver is alerted to this condition by the illumination of the

“WARNING” legend, and the computer will also issue a 5-beep two tone

audible alarm once every two minute to alert the diver to this condition.

The Maximum Depth will be replaced with “S-d“ or "S--" to indicate the low-

pressure transducer or “S-t” for the temperature transducer (see figure

18a). The “WARNING” legend, along with either the Temperature digits or

the Depth digits and the error code will flash once per second. In the

highly unlikely situation were both sensors are detected as having errors,

the display will alternate between “S-d“ or "S--" and “S-t”. This warning will

be issued whether the computer is in the Surface Interval, Dive Mode,

Decompression Mode or Post Dive Interval. In the unlikely case that your

computer issues one of these warnings the unit should be returned to the

factory for evaluation and/or repair.

Figure 18a shows a Sensor Warning, in this case a Temperature Sensor,

as it would be displayed in the Dive Mode. If the Sensor Warning was for

the depth sensor it would display “S-d“ or "S--".

OXYGEN TOXICITY FACTORS: The EMC-16 has the ability to track

Oxygen Toxicity levels for the Central Nervous System (CNS) as well as

the Mission Oxygen Tolerance Units Dose (OTU). In addition, a maximum

Partial Pressure of Oxygen (PO2) warning alarm can also be set. While

most other audible alarms of the dive computer consist of five long beeps,

the CNS, OTU, and PO2have a distinctive audible alarm that consists of

short double-beeps that sound once per second for five seconds.

As long as one or more of these three parameters is outside its limits, the

“WARNING” legend on the display will continue to flash and the audible

alarm will be repeated once every two minutes.

These three functions are not active if the NITROX capability is disabled

via the Analyst®PC Interface.

PARTIAL PRESSURE OF OXYGEN (PO2): High levels of PO2can cause

severe Oxygen poisoning. Individual divers can be affected by widely

different levels of PO2. The user via the Analyst®can set the PO2alarm to

any level between 0.50 ATA and 1.59 ATA. As shipped from the factory,

this is set to 1.40 ATA. Should the PO2be above the alarm set point, the

“WARNING” legend will illuminate and the audible alarm will sound and the

PO2value that is displayed will flash.

CENTRAL NERVOUS SYSTEM (CNS) TOXICITY: The user via the

Analyst®can set the CNS Toxicity alarm to any level between 40% and

80% of the maximum allowable limit. As shipped from the factory, this is

set to 50%. Should the CNS Toxicity reach 50% of the maximum

allowable, the “WARNING” legend will illuminate and the audible alarm will

sound and on the Alternate Screen the displayed CNS percentage will be

flashing along with the “WARNING” legend.

By the accepted definition of CNS toxicity, should a PO2value of greater

than 1.6 ATA be measured, the CNS Toxicity will be 100%. During the

Surface Interval, this percentage will decrease as the CNS declines toward

zero. Whatever the current CNS Toxicity level, it can also be viewed on

the Surface Interval Alternate Screen or on the InFormation screen in the

Programming Mode.

OXYGEN TOLERANCE UNITS (OTU): An issue with long term breathing

of higher partial pressures of Oxygen above 0.5 ATA is Pulmonary Oxygen

Toxicity or sometimes called WHOLE BODY which must be tracked

properly.

The EMC-16 will track the OTU based on Dr. Bill Hamilton’s ‘REPEX’

method of oxygen exposure management. The OTU Dose is an

exponential function of oxygen partial pressure and time.

The time-dependent limit varies with length of time (days) that the diver

continues to dive without full recovery to zero OTU. The Mission OTU

Clock tracks the OTU, which is a running clock that tracks long-term

Oxygen exposure. This clock may run for several weeks if frequent dives

are made using high levels of PO2. The current Mission Clock, CNS, and

OTU can be seen via the Analyst®PC interface or the current CNS and

OTU values can be viewed on the Alternate Screen while in the Surface

Interval, Dive Mode, Decompression Mode or Post Dive Interval. The

current CNS and OTU values can also be viewed via the Touch Contact

Programming mode by selecting the InFormation option. The recovery

portion of the OTU algorithm is a linear reduction of OTU over time. The

Mission OTU clock is reset to 0:00 when the OTU Dose reaches zero.

The user via the Analyst®can set the OTU Toxicity alarm to any level

between 40% and 80% of the maximum allowable limit. As shipped from

the factory, this is set to 50%. Should the OTU Dose reach 50% of the

maximum allowable, the “WARNING” legend will illuminate and the audible

alarm will sound and on the Alternate Screen the displayed OTU value will

be flashing along with the “WARNING” legend.

Symptoms of Pulmonary Oxygen Toxicity include burning in the throat and

chest, coughing, and shortness of breath. Discontinue diving and consult

a Physician should any of these, or other, symptoms appear.

Figure 39 shows a CNS exposure over the alarm set point (50%), in the

situation were both the CNS and the OTU exposure was over their set

points both values would flash.

EMC-16 – USING TWO GAS NITROX

OVERVIEW: The EMC-16 is capable of being used for two different Nitrox

mixtures on the same dive. The first gas or Normal Blend is

programmable from 21% to 50% Oxygen in 0.1% increments while the

Deco Blend can be programmed from 21% to 99.9% Oxygen again in

0.1% increments. Both Blends are set at the factory to 21% Oxygen and

use this in its decompression algorithm. PRIOR to diving an Enriched Air

Nitrox gas blend, the unit must be programmed accordingly. This can be

done via the Touch Contacts or via the Analyst®PC Interface.

GAS BLEND SWITCHING: While most other Nitrox dive computers limit

the diver to the use of a single gas blend or percentage of oxygen, the

EMC-16 allows the diver to use two different gas blends during a dive.

These two gas blends are commonly referred to as the Normal or Bottom

Gas Blend and the Decompression Gas Blend. Commonly, the Bottom

Gas Blend is used from initial entry into the water and for most of the time

spent during the dive. The Normal Gas Blend is restricted to a maximum

of 50% oxygen. The Decompression Gas Blend (Deco Blend) is used only

for decompression purposes and can go to 99.9% oxygen content.

Typically, the Deco Blend is in a cylinder that is suspended at some

relatively shallow depth beneath the surface.

Since the depth of the Deco Blend switch is known ahead of time, and the

expected duration of the dive is also known, these two factors can be used

to automatically switch the computer to the Deco Blend or back to the

Normal Blend should the diver descend again. This is accomplished prior

to starting a dive by specifying both the Normal Gas Blend Oxygen

percentage and the Deco Gas Blend Oxygen percentage. The depth of

the Deco switch is also specified. Depending on surface swells, a few feet

may be added to this depth to ensure that when the diver is shallower than

the depth the Deco Blend will actually be in use. If the diver subsequently

descends below this depth, the Bottom (Normal) Blend is again assumed

to be in use. The other important factor that must be specified is the

Bottom Time that must elapse before Blend Switching is enabled. The

purpose of this factor is to ensure that the switch to the Deco Blend does

not occur prematurely should the diver ascend early and not require use of

the Deco Blend, the setting of this factor must be carefully considered.

The Deco Blend switch is enabled when the diver descends below the

switch depth and satisfies the time requirements and then ascends to the

programmed switch depth. If the diver does not exceed the programmed

switch depth the unit will not switch to the Deco Blend. All of these factors

can be set by either the touch contact programming or via the Analyst®PC

interface. If switching to the Deco Blend is NOT desired, it may be

disabled via the Analyst®. Setting both Blends to the same percentage of

Oxygen is the same as disabling the Deco Blend.

TOUCH CONTACT PROGRAMMING SCREENS: The following are all of

the screens that the EMC-16 is capable of presenting in the Touch

Programming Mode. Refer to the particular configuration for appropriate

screens.

INTER-DIVE EVENTS: The EMC-16 stores important information

between dives, even when the unit is not turned on. The information is

stored as acquired and is called an “Inter-Dive Event”. These events can

be viewed via the Analyst®P.C. Interface version 4.01 or higher. Some

Inter-Dive events are:

•Initialization of the unit.

•The unit is turned on

•Low batteries

•Altitude Changes of over 500 feet

•Sensor Malfunction

•Analyst®P.C. Communication

USER CONFIGURABLE ITEMS: The number of and which of the

configurable options are viewed is determined by the configuration of your

EMC-16.

Caution: Items that can be changed via Touch Contact Programming

may be different from their factory settings.

By using the optional Analyst®Personal Computer Interface, the user has

the ability to change the following items:

Dive Time/date Stamp: This is the internal clock setting that is used by

the system to time-stamp each individual dive as it occurs. Due to

changes in battery voltage and temperature, the internal Time-of-day clock

may slowly drift from the ideal. It is recommended that this clock be

periodically set to your local time via the Analyst®.

Metric or Imperial: The diver may select whether the data is computed

and displayed in Metric or Imperial units. The EMC-16 may be ordered

either way as shipped from the factory.

Selectable Ascent Rate Bar Graph (Fixed or Proportional): This option

determines whether the Ascent Rate bar graph indicates the speed of

ascent or the percentage of the selected maximum ascent rate. The EMC-

16 is shipped from the factory as ‘Proportional’ (percentage).

Selectable Variable-By-Depth Ascent Rate Alarm (On or Off): This

option gives the diver the ability to utilize a fixed ascent rate warning or a

warning based on depth. Should the diver prefer the fixed ascent rate

warning the diver can select the maximum ascent rate limit of from 20 to

60 feet per minute (See next topic). As shipped from the factory, this is set

to ON. If the VARIABLE rate is selected then the warning will illuminate

based on the following table:

DEPTH AVERAGE ASCENT RATE

60 feet and deeper 60 feet per minute

60 to 30 feet same as depth

Shallower than 30 feet 30 feet per minute

Selectable Fixed Ascent Rate Alarm Limit: If Variable-By-Depth Ascent

Rate Alarm was set to OFF from the above topic, the user may enter the

desired Ascent Rate for the alarm to sound.

Ascent Rate for Deco Predictions (20 to 60): This option allows the diver

to select the ascent rate to be used in the forecasting of the displayed Total

Decompression time. The EMC-16 is shipped from the factory with this

option set to 60.

Ascent Rate Responsiveness (0 to 7): This option determines the

responsiveness or sensitivity of the Ascent Rate Bar Graph. Zero is highly

responsive and seven is very slow. This feature is set to three as shipped

from the factory.

Remaining Time Responsiveness (0 to 7): This determines the

responsiveness of the Remaining Time information that is displayed. Zero

is highly responsive and seven is very slow. This feature is set to three as

shipped from the factory

Max Depth Alarm: This option allows the diver to select a maximum

depth below, which the diver does not wish to exceed before an alarm is

sounded. This function is disabled when in the Decompression Mode. This

option may also be set via the Touch Contact Programming. As shipped

from the factory, the Depth Alarm is set for 130 feet.

Select Decompression Time Display (Total, Stop, Both): There are

three options for the manner in which the decompression time is displayed.

If you select TOTAL, the decompression time displayed will indicate the

total time you will spend in decompression.

Watch the Ceiling depth change in order to identify when to ascend to the

next stop depth. If you select STOP, the decompression time displayed

will indicate the time you must remain at the current Ceiling. When this

time is 0:00, the Ceiling depth will decrease and the new stop time will be

displayed. If you select BOTH, the TOTAL time and STOP time will

alternate at the rate of once every 2 seconds. From the factory, the unit is

set to ‘Both’.

Repetitive Dive Dependent Nitrogen (Off or On): This option allows the

dive computer to consider recent dive history’s effects on the nitrogen

loading, particularly if the diver engages in inverted profile diving. If “On”

the recent dive history is used to compensate the nitrogen loading for the

current dive. The EMC-16 is shipped from the factory with this feature set

to ‘On’.

Temperature Dependent NDC Computations (Normal or Reduced):

This feature compensates the decompression algorithm proportional to the

ambient water temperature. See User & Environmental Adaptation, Water

Temperature on page 17 for a detailed description of this function. The

EMC-16 is shipped from the factory with this feature set to ‘Normal’.

Select Altitude <2000 feet as One Zone (Off or On): This option

provides "actual" altitude for any given day at any diving location as

explained in the “ALTITUDE ACCLIMATIZATION” on page 17. With

changes in barometric pressure due to temperature and weather systems,

it is possible, even expected, to have a different apparent altitude at the

same dive site from day to day.

While the seamless means of monitoring provides the most accurate

decompression schedule, all altitudes less than 2,000 feet above sea level

can be treated in the algorithm as sea level if so selected. With this option

OFF, the unit is calculating altitude in a seamless fashion. With this option

ON altitudes less than 2,000 feet above sea level will be treated as sea

level. Regardless of the selection, altitudes greater than 2,000 feet above

sea level will be treated in a seamless manner. From the factory, this is

set to ‘Off’, seamless altitude from sea level to 15,000 feet.

Select Alternate Screen Viewing Time (3 to 10): This option allows the

diver to set the amount of time that the Alternate Screen will be viewed

once it has been accessed. From the factory this is set to 4.

Select Display Backlight On Time (0 to 99): This option allows the user

to set the amount of time, in seconds, that the TACLITE™ stays on once

activated. If this option is set to "0" the TACLITE™ will never activate, if

set to "99" the TACLITE™ will stay on all the time and only turn off when

the EMC-16 does. From the factory this is set to 10. This option may also

be set via the Touch Contact Programming method.

Select Audible Beeper Alarm (On or Off): This allows the user to enable

or disable the Audible Alarms and beeper. As shipped from the factory, this

is set to ‘On’.

Select Ceiling Display Divided by 10 (On or Off): This option allows the

diver to select when in the Decompression Mode the Ceilings are

displayed as 1 = 10, 2 = 20, 3 = 30 etc. (On) or as 10, 20, 30 etc (Off).

From the factory this option is set to ‘Off’.

Select Nitrox Computations (Off or On): This option enables and

disables NITROX computations. If this option is disabled, mixtures other

than 21.0% oxygen will be disallowed. Furthermore, if this option is

selected as OFF, the EMC-16 will not compute CNS Toxicity, OTU Dose,

or maximum PO2 alarm. The factory setting for this option is ‘On’.

Enter Normal Blend Oxygen % in FO2Nitrox Mixture (21.0 to 50.0):

For Constant FO2mode, this option allows the user to enter the desired

Oxygen percentage for the FO2Blend in 0.1% increments. Values from

21.0% to 99.9% may be entered. This option may also be set via the

Touch Contact Programming method. As shipped from the factory, this is

set to 21.0%.

Enter Deco Blend Oxygen % in FO2Nitrox Mixture (21.0 to 99.9): For

Constant FO2mode, this option allows the user to enter the desired

Oxygen percentage for the FO2Deco Blend in 0.1% increments. For

Constant PO2mode, this option specifies the FO2blend percentage if and

when the unit switches to FO2computations. Values from 21.0% to 99.9%

may be entered. This option may also be set via the Touch Contact

Programming method. As shipped from the factory, this is set to 21.0%.

Enter Deco Blend Bottom Time Activation Minutes: Here, you will

enter the bottom time benchmark for switching to the Deco Blend. The

Field Programming Mode previously described may also modify this

setting. As shipped from the factory, this is set to 600. This option may

also be set via the Touch Contact Programming method.

Enter Deco Blend Ascent Depth Activation: Here, you will enter the

depth benchmark, which you will need to be above for switching to the

Deco Blend. The Field Programming Mode previously described may also

modify this setting. As shipped from the factory, this is set to 10 feet. This

option may also be set via the Touch Contact Programming method.

Select Deco Blend Nitrox Switching (Enabled or Disabled): This

option enables the unit to switch to the Deco blend. If it is disabled the

EMC-16 will not switch to the Decompression gas blend. As shipped from

the factory, this set to ‘Enabled’.

High PO2 Alarm Point (0.50 to 1.59): This option allows the diver to

select a maximum PO2 (Partial Pressure of Oxygen) at which an alarm is

sounded. Values from 0.50 to 1.59 are allowed. This is set to a PO2 of

1.40 at the factory before shipping.

Selectable NDC Conservatism (0% to 50%): This feature allows the

diver to input an added degree of conservatism to the decompression

algorithm from 0 to 50 percent in one-percent increments. This may be

desirable if the diver is dehydrated, tired, or has some other factor that

warrants added conservatism. This option may also be set via the Touch

Contact Programming. Conservatism is set to ‘0%’ as shipped from the

factory.

Enable Mix Switching In Deco Forecast (Enabled or Disabled): This

option enables the unit to forecast decompression times utilizing the

programmed deco gas for stops that are shallower than the switch depth.

As shipped from the factory this option is disabled.

High CNS Alarm Point (40% to 80%): This option allows the diver to

select a maximum CNS (Central Nervous System) exposure at which an

alarm is sounded. Values from 40% to 80% are allowed. This is set to

50% at the factory before shipping.

High OTU Alarm Point (40% to 80%):This option allows the diver to

select a maximum OTU (Oxygen Tolerance Units) exposure at which an

alarm is sounded. Values from 40% to 80% are allowed. This is set to

50% at the factory before shipping.

Confined Water Protocol (Training Mode) - (Enabled or Disabled):

This option enables the Training Mode for the EMC-16. In this mode the

EMC-16 will enter the Dive Mode at 2 feet instead of 5 feet and exit the

Dive Mode at 1 foot instead of 3 feet. The Training Mode also permits the

selection of an increased Post Dive Interval period from 10 to 30 minutes

in one-minute increments. These changes permit the Instructor to record

a complete training session, including in-water surface periods, as a single

dive. As shipped from the factory, this is set to ‘Disabled’. This option can

only be ‘Enabled’ via the Professional Edition of the Analyst®.

Training Mode Post Dive Interval Period (10 to 30): If the Training Mode

is enabled this allows the user to select the duration of the Post Dive

Interval period from a minimum of 10 minutes to a maximum of 30 minutes

in one-minute increments. As shipped from the factory, this is set to 10.

This option can only be set via the Professional Edition of the

Analyst®.

Select Clock Functions (ON or OFF): This option allows the diver to

enable or disable the time of day Clock. If set to ON the clock time can be

set via Touch Contact Programming method. As shipped from the factory,

this is set to OFF.

Enter Clock Time: This allows the diver to set the clock’s time to that of

the P.C. time.

Select Alarm Clock Audible Alarm (ON or OFF): This option allows the

diver to enable or disable the time of day Clock’s Alarm feature. If set to

ON the Alarm Clock time can be set via Touch Contact Programming. As

shipped from the factory, this is set to OFF.

Enter Alarm Clock Hour (0 to 23): This allows the diver to program the

time of day Alarm Clock’s hour setting. The Alarm Clock’s time utilizes a

24 hour format, i.e. 0 = 12:00 am, 20 = 8:00 pm, etc. This is also settable

via Touch Contact Programming.

Enter Alarm Clock Minute (0 to 60): This allows the diver to program the

time of day Alarm Clock’s minute setting. This is also settable via Touch

Contact Programming.

Restore Original Configuration Settings: This allows the diver to restore

the original factory default settings with a single command.

Note: Specifications are additionally +/- one least significant digit due to rounding. Specifications

are subject to change without notice.

CLEANING THE EMC-16: Clean the unit only with fresh water after each

use and towel dry; never use air pressure to dry the unit. This could

damage the unit and will void the warranty. Do not use chemicals to clean

the case or lens as this may damage the unit, or permanently fog the lens.

CHANGING BATTERY: The EMC-16 will operate on either one 3V

Lithium Battery (CR12600SE or CR2NP) this is the recommended battery

or two 1.5V N-Cell size Alkaline battery(s) if a 3V Lithium battery is not

available. The batteries should be changed when the ‘BATT’ legend is

seen or battery voltage reaches 2.5 volts as can be seen on the

Information Display. The unit will operate until the battery voltage drops

below 2.0 volts. Only use fresh batteries for maximum battery life. At this

time, Eveready Energizer Alkaline is recommended for the N-Cells. Care

should be taken not to activate the TACLITE™ during battery replacement.

Be sure to confirm that the batteries are REALLY new and have not been

sitting on a shelf losing life. Cold temperatures tend to shorten apparent

battery life. Change batteries every two years regardless of battery

condition.

Plus end goes in First.

CAUTION!!! Putting the battery(s) in backwards may cause

permanent damage to the unit and will VOID the Warranty.

When installing new batteries, ensure that the positive “+” end of the

battery is inserted into the battery compartment first. Inspect the battery

cap O-rings for nicks and scratches. If either O-ring is damaged carefully

remove both O-rings and replace with new silicone O-rings. Lightly

lubricate each end of the batteries with silicone grease or petroleum jelly to

help minimize corrosion and therefore extend battery life.

When reinstalling the battery cap, lightly lubricate the O-rings and slowly

twist the cap into place using a coin (US Quarter supplied). Press the coin

into the battery cap slot firmly to prevent slipping and damaging the slot.

Ensure there is no dirt or debris on the O-rings or the mating surface and

that the O-rings are properly installed.

As the battery cap is screwed in, carefully observe that the double O-rings

install correctly.

It is best to have the new batteries ready to install since the EMC-16 was

designed to allow for battery changes without resetting. This period of

time is typically 30 seconds, but varies with temperature and the voltage of

the batteries being replaced. It can be significantly less if batteries are not

replaced promptly when the ‘BATT’ legend first comes on. Again care

should be taken not to activate the TACLITE™ during battery replacement,

if the TACLITE™ is activated it will significantly reduce the time that the

EMC-16 allows for battery changes.

If the batteries are allowed to discharge too low, or if removed for too long,

the EMC-16 may enter a state where it will not turn on even with new

batteries. If this occurs, remove the batteries and allow the unit to set for

60 minutes and then install fresh batteries. This procedure will affect the

internal Time of Day Clock’s settings and these settings should be verified

via the Analyst®P.C. Interface.

CAUTION!!! COMPLETE LOSS OF BATTERY POWER MAY CAUSE

ALL PREVIOUS DIVE NITROGEN LOADING TO BE LOST. THIS WILL

AFFECT NITROGEN CALCULATIONS ON NEAR-FUTURE DIVES.

AFTER A BATTERY CHANGE, CONFIRM THAT NO-DECOMPRESSION

TIME DATA IS REASONABLE IN THE PRE-DIVE PREDICTION MODE.

DIVE-OF-DAY NUMBER GOING TO ZERO IMMEDIATELY AFTER

CHANGING BATTERIES IS ANOTHER INDICATION OF A LOSS OF

NITROGEN LOADING.

STATEMENT of LIMITED LIABILITY

A mathematical model is used by this Product to calculate physiological

effects of SCUBA diving related to use of compressed air or other

breathing mixtures while at depth. Such effects specifically relate to

nitrogen absorption into and elimination from body tissues, as well as

effects of oxygen used in Enriched Air Nitrox breathing mixtures.

However, because of the number of variables and the varying degrees to

which they may affect individuals engaged in SCUBA diving, COCHRAN

DOES NOT GUARANTEE THAT USE OF THIS PRODUCT WILL

PREVENT DECOMPRESSION SICKNESS OR ANY OTHER CONDITION

OR INJURY INCURRED WHILE USING THIS PRODUCT.

These influencing variables may include, but are not limited to,

dehydration, obesity, age, old injuries, or other physical conditions on the

part of the diver, or environmental extremes of heat or cold, or poor

training, or diving practices, any of which may promote the onset of

decompression sickness or other harmful effects.

This Product is sold and intended to be used only as a guide, providing the

TRAINED and CERTIFIED diver the information needed to make safe

diving decisions. It is expressly understood that by buying and/or using

this Product the Diver assumes ALL RISK as to its operability, reliability,

quality, performance, accuracy, and suitability for his diving style.

Furthermore, Diver recognizes that this Product is an electronic instrument

being used in a hostile environment and is subject to failure, which may

manifest itself in a number of ways. COCHRAN and its distributors and

retailers will not be held liable for any personal injuries or other damages

resulting from its use, even if COCHRAN has been advised of such

occurrences or damages.

These products must be handled with care and properly maintained to

assure the optimum performance. Users must possess the proper training

for SCUBA diving activities and should be fully educated in the operation

of this product. Users are encouraged to possess and utilize a redundant

(backup) computer for their dive planning and execution. Divers are

always encouraged to dive with a buddy at all times.

COCHRAN strongly supports and agrees with maximum depth limits of

130 feet for recreational SCUBA diving, as established by recognized

training and certification agencies, and in no way encourages diving

beyond these or any prudent lesser limits as may be necessitated by

environmental, diver-specific, or other conditions.

No Cochran Undersea Technology dealer, agent, or employee is

authorized to make any modification, extension, or addition to this

warranty.

USER & ENVIRONMENTAL ADAPTATION: The EMC-16 is one of the

new breed of Dive Computers that adapts its algorithm to the users diving

environment and style as originally pioneered by COCHRAN. All of

COCHRAN’s newer dive computers incorporate this capability. The factors

that are used for this “Adaptation” in the EMC-16 are:

Water Temperature Salt/Fresh Water Compensation

Microbubble Altitude Acclimatization

User Conservatism Previous Dive Profiles

WATER TEMPERATURE: Diving in cold water can lead to a lower diver

core and skin temperature which can affect the gas exchange rate of the

body’s tissues. The EMC-16 features two modes of Temperature

Compensation, Normal or Reduced. The EMC-16 progressively makes its

nitrogen algorithms more conservative as the water temperature declines

below 75 degrees F. Above this water temperature, there is no

temperature compensation. In the Reduced Mode, the algorithms are

made more conservative by approximately one-half the amount of the

Normal Mode. If the diver is wearing an insulated dry suit and is relatively

warm even in cold water, this temperature compensation factor may be set

to Reduced Mode at the divers discretion using the Analyst®PC software.

MICROBUBBLE: There are several theories regarding the exact method

by which a nitrogen bubble forms from a microbubble which was formed

from micronuclei. Currently the predominant theory states that more rapid

ascents accelerate bubble formation. The EMC-16 comprehends and

adjusts for this phenomenon.

USER CONSERVATISM: Current dive computers cannot tell if the diver is

dehydrated, tired, smokes, overweight, or has some other physical issue

that may require additional conservatism in the nitrogen algorithm. The

EMC-16 allows the diver to input an added degree of conservatism to the

nitrogen algorithm from 0 to 50 percent in one-percent increments. This

can be done via the Touch Contact Programming Mode or with the

Analyst®Personal Computer Interface.

PREVIOUS DIVE PROFILES: Under some circumstances, recent dive

activity can have an effect on nitrogen loading, particularly if the diver

engages in inverted profile diving. This occurs when a deep dive is

followed by an even deeper dive. This recent dive history is used to

compensate the nitrogen loading for the current dive. This can be enabled

or disabled with the Analyst®Personal Computer Interface.

SALT/FRESH WATER COMPENSATION (High/Low Water

Conductivity): There is approximately a three percent difference in depth

readings taken in salt water versus fresh water. Some dive computers are

calibrated in feet of fresh water and some are calibrated in feet of

seawater. Diving in a medium different from what the dive computer is

calibrated for will cause apparent depth errors. Only COCHRAN dive

computers, including the EMC-16, actually determine the type of diving

medium and compensate the depth reading accordingly. This is

accomplished by measuring the conductivity of the water during a dive.

Caution must be taken in interpreting this reading since some apparent

fresh water is actually high in minerals or contaminants and is correctly

compensated as salt water (High Conductivity). This commonly occurs in

some caves, springs, and lakes.

ALTITUDE ACCLIMATIZATION: Driving or flying to a dive site

significantly higher in altitude requires special modifications to the "sea

level" algorithm. The EMC-16 regularly samples the ambient barometric

pressure to determine these changes in altitude whether the unit is On or

Off. Accordingly, the decompression algorithm is changed to reflect these

barometric pressure changes. Note that temperature and weather systems

also affect barometric pressure and hence, apparent altitude. Using the

Time-To-Fly digits, the number of hours required to “adapt” to the new

altitude is immediately known to the diver. If a significant altitude change

occurs, a minimum of one hour should pass before diving to allow the unit

to adapt to this new altitude. Rapid changes in altitude should be avoided.

The dive computer may interpret a rapid change from a higher altitude to a

lower altitude as a dive. Should this occur, removing the batteries for ten

minutes will reset the computer, however, all tissue nitrogen loading will

also be lost.

Should it be desired to initiate a dive PRIOR to completing the adaptation

time, the EMC-16 will treat this dive as a repetitive dive in its algorithm,

taking into account the "residual" nitrogen present due to travel to altitude.

There are two methods of compensating for altitude. Via the Analyst®PC

Interface, ZONE or SEAMLESS altitude compensation may be selected.

In ZONE all altitudes less than 2,000 feet above sea level use the sea-level

algorithm. At altitudes greater than this, altitude compensation is

“seamless”; literally, every small fraction of gained altitude is considered in

adjusting the algorithm. ZONE will reduce the occurrences of obtaining

slightly different altitude readings and corresponding no-decompression

(NDC) limits when diving within a given area. However, ZONE reduces the

accuracy of the altitude compensation for the first 2,000 feet above sea

level, since all altitudes below 2,000 feet are treated as sea level. The

advantage in ZONE is that changes in apparent altitude due to

temperature or weather changes at sea level will not affect the NDC

computations.

In SEAMLESS, the algorithm is adjusted for extremely small changes in

altitude. However, a difference in altitude may be seen from day-to-day at

a given dive site due to temperature or weather systems and their effect on

barometric pressures. SEAMLESS will provide the most accurate altitude

compensation algorithm, but normal variations in atmospheric barometric

pressure may affect the no-decompression time which is more

predominantly seen in the Pre-dive Prediction forecast.

CAUTION: The EMC-16 will not perform Altitude Acclimatization if the

touch contacts are shorted or bridged. Rinse the unit with clean

fresh water and dry it with a towel after each dive. Transporting

and storing the unit in its case will help prevent the possibility of

the contacts being shorted or bridged.

WARNING: While your EMC-16 will automatically adjust its no

decompression algorithm for altitude, you should NOT attempt

to dive at altitudes greater than 1,000 feet above sea level

without first completing a sanctioned altitude diving course from

a recognized training agency for recreational diving. The EMC-

16 should not be used for this type of diving by anyone without

this important training.

METRIC/IMPERIAL MODES: If the computer is computing and displaying

in Metric, the “METRIC” legend will be illuminated when the computer is

on. Metric/Imperial selection is made using the Analyst®software.

Changing Modes does not affect any profiles or data stored in the

computer.

LOW BATTERY INDICATIONS: Fresh batteries should read about 3.2

volts on the Information Screen. When the battery voltage drops to 2.5

volts, the “BATT” legend will be illuminated. It is recommended to change

the batteries at this point, but several dives might still remain possible.

When the battery voltage decays to 2.2 volts, the “BATT” legend will begin

to flash on and off. Once the “BATT” legend begins to flash the

TACLITE™ is deactivated, to conserve the remaining battery power even

though the unit may be on a dive, and can not be activated until fresh

batteries are installed. While there should be sufficient battery power to

normally complete a dive, it is not recommended to begin a new dive until

fresh batteries are installed. After the computer automatically turns itself

off 70 minutes after a dive, it cannot be turned back on if the battery

voltage is less than 2.0 volts. Fresh batteries must be installed. See the

“BATTERY CHANGES” section of this manual for detailed information on

how to change batteries.

CAUTION!!! COMPLETE LOSS OF BATTERY POWER MAY CAUSE

ALL PREVIOUS DIVE NITROGEN LOADING TO BE LOST. THIS WILL

AFFECT NITROGEN CALCULATIONS ON NEAR-FUTURE DIVES.

AFTER A BATTERY CHANGE, CONFIRM THAT NO-DECOMPRESSION

TIME DATA IS REASONABLE IN THE PRE-DIVE PREDICTION MODE.

DIVE-OF-DAY NUMBER GOING TO ZERO IMMEDIATELY AFTER

CHANGING BATTERIES IS ANOTHER INDICATION OF A LOSS OF

NITROGEN LOADING.
