WARNING

Read this manual carefully and pay attention to all warnings. Make sure you fully

understand the use, displays and limitations of the watch. Neglecting to understand

and follow the instruction manual may cause errors to be made during diving that may

lead to serious injury or death.

Thank you for your purchase of the Citizen CYBER AQUALAND. Please read this manual

carefully before using your watch to ensure that it is used properly. Furthermore, make

sure to store this manual in a safe place for future reference as necessary.

CYBER AQUALAND is a diver's watch containing a built-in dive computer and provided

with its own depth gauge. The watch is able to automatically store various data (maximum

depth, dive time, etc.) generated during diving as well as diving profile data, and display

that data in the form of log data.

By installing AQUALAND GRAPH 2001 in your personal computer from the CD-ROM

provided with the watch, you can incorporate data stored in the watch in your PC using the

communication unit and infrared communication interface provided. You can enter text

into diving data that has been incorporated into your PC, generate graphs of diving data or

attach still pictures or animated image data all with a simple procedure, and then manage

this data collectively in the form of diving logs. Since these logs can be printed out or

converted into HTML documents, storage of diving records is both simple and convenient.

In addition, the use of CAPgm, which is installed simultaneous to installation of

AQUALAND GRAPH 2001, makes it possible to make various watch settings (including

travel time, alarm and timer settings) while also allowing different graphics to be displayed

on the watch for different days.

We hope that the use of CYBER AQUALAND will allow you to get even more enjoyment

out of your recreational diving activities.

* To users using a previous HYPER AQUALAND product (Model No. D20*):

• If you are using the DOS version or Windows Ver. 1/Ver. 2 of AQUALAND GRAPH

(HYPER AQUALAND dedicated software), you can use existing diving data managed

with each version of AQUALAND GRAPH by importing that data to AQUALAND GRAPH

2001.

• HYPER AQUALAND data can also be received using AQUALAND GRAPH 2001

software. Please note, however, that the type of communication unit and connection

cable differ between CYBER AQUALAND and HYPER AQUALAND.

(Please refer to the AQUALAND GRAPH 2001 instruction manual contained on the CD-

ROM provided for further information regarding the procedures for importing and

receiving data.)

WARNING

In order to ensure safe diving, dive while allowing an adequate margin of safety

relative to the displayed no-decompression limit time.

WARNING

Never dive in a manner that requires a decompression stop (decompression diving).

If decompression diving should happen to occur, immediately start to ascend while

observing an ascent rate of no more than 18 m/min. Make a decompression stop

while ascending in accordance with decompression stop instructions.

When making a decompression stop, never ascend to a depth less than the instructed

depth. In addition, since it is difficult to maintain a constant depth when there are high

waves and so forth, make decompression stops at depths a little deeper than the

instructed depth to prevent decompression sickness.

* A permanent error (ERROR) occurs when continuing to dive while ignoring decompression

stop instructions during the course of decompression diving, and the watch will not switch to

the dive mode for 24 hours after that time.

WARNING

Avoid traveling in an aircraft while the surface mode is activated. Traveling in an

aircraft without allowing sufficient time to rest after diving results in the risk of

decompression sickness. It is recommended to avoid traveling in an aircraft for at

least 24 hours after diving whenever possible even if the surface mode is no longer

displayed. There are no rules for completely preventing decompression sickness

caused by flying in an aircraft after diving.

CAUTION

Skin diving after scuba diving is not recommended. It is recommended to avoid skin

diving for at least two hours after scuba diving and not to exceed a depth of 5 m.

Data Storage

• The various data recorded in the watch may be lost when subjected to incorrect use

or the effects of strong electricity and electrical noise as well as during a malfunction

and repair. Always make sure to keep a separate record of important data recorded

in the watch. Diving data in particular should be transferred to your PC or recorded

in a log book as quickly as possible.

7978

WARNING

• Diving is a potentially dangerous sport. When using this watch for diving,

make sure to have a correct understanding of this watch as described in

this manual and strictly adhere to the procedures for its operation. The

watch may not function properly if handled in a manner not described in

this manual.

• This watch should not be used as a primary instrument for diving.

• Diving while using this watch is limited to recreational diving (no

decompression diving) in salt water at a water temperature of +10°C to

+40°C. This watch cannot be used for decompression diving, saturation

diving using helium gas, diving at high altitudes (300 m or more above sea

level) or diving outside the above temperature range. In addition, this

watch can not be used for nitrox diving (diving using a mixed gas of oxygen

and nitrogen in which the oxygen concentration is richer than air tanks used

for ordinary diving).

• Although this watch provides data for decompression diving in cases of

emergency, never attempt to use this watch for decompression diving since

this is potentially dangerous.

In addition, the watch does not display depth correctly when used in water

other than salt water (specific gravity: 1.025).

• Even recreational diving can be dangerous. Users are requested to obtain

the proper scuba diving training from a qualified instructor, acquire the

necessary experience and skills for safe diving and completely master the

handling and operation of this watch before using this watch as an auxiliary

instrument for diving. Insufficient or improper training may cause errors to

be made during diving that may lead to serious injury or death.

• Sudden atmospheric fluctuations and changes in water temperature may

have an effect on the display and performance of the watch. Since this

watch is not intended to be used as a specialized instrument, and is only

intended to display information to serve as a reference for minimizing

decompression sickness and other dangers, it is not designed to guarantee

the safety of the user. Always make sure to use this watch in combination

with other instruments (such as a diving table, residual pressure gauge and

water depth gauge). Never use it as a primary instrument for diving.

• This watch is designed on the premise of being used only by one person.

Never lend to or share this watch with another person while resting on the

surface (while the surface mode is activated). In addition, do not use the

data displayed by the watch as diver data for persons other than the user.

due to the band being too short, remove the leg of the communication unit (removable). Slide

the watch through the location where the leg was removed to attach to the communication unit.

WARNING

When removing the leg from the communication unit, keep the removed leg out of the

reach of children to prevent accidental swallowing.

8786

• Confirm that "ERR" (error) or "CHK" (check) is not displayed on the display.

• Confirm that the band is securely attached to the watch body.

• Confirm that the band and glass are free of cracks, scratches, chips and other

abnormalities.

• Confirm that the time and date are set correctly.

• Confirm that the depth alarm and dive time alarm are set correctly.

• If there is a considerable difference between the watch temperature and the water

temperature (such as in cases of entering water after having the left the watch in bright

sunlight), water depth cannot be measured accurately. In such cases, immerse the

watch in the water for at least 5 minutes and then dive after the watch temperature has

become acclimated to the water temperature.

• Avoid ascending too rapidly. Rapid ascending can cause decompression sickness and

have other detrimental effects on the body. Observe the safe ascent rate at all times.

• Please note that when underwater, it may be difficult to hear the sound of the dive alarm

or other alarms depending on surrounding conditions (such as breathing noise and air

bubble noise) and the manner in which the watch is worn.

• Be careful not to run out of air. This watch does not manage the amount of air remaining

in the air tank. The diver is responsible for managing the amount of air remaining.

• In the event the watch should happen not to operate properly while underwater, either

ascend immediately while following the instructions of the instructor or begin ascending

immediately at an ascent rate of no more than 18 m per minute and make a safety stop

at 5 m as long as your air lasts.

• Make sure to rest sufficiently after diving by checking the surface mode (which measures

the amount of time elapsed after diving and no fly time).

• After removing any moisture, mud, sand or other foreign matter adhered to the watch by

thoroughly rinsing with fresh water, completely wipe off the watch with a dry cloth.

• Do not attempt to remove the sensor cover or poke at it with a sharp object to attempt to

remove any dirt or debris trapped in the pressure sensor. In addition, do not spray the

pressure sensor with air under high pressure such as that from an air gun. In the case

that debris has become trapped in the pressure sensor, rinse it out with fresh water. If it

is still unable to be removed, consult Citizen Consumer help desk or your nearest

Customer Support Center.

CAUTION Fresh Water Diving

• This watch is designed on the premise of diving in salt water. It will not display water

depth accurately in water other than salt water.

• Only use the watch after receiving special safety training when using the watch for diving

in fresh water.

• Since this watch displays water depth as converted based on salt water (specific gravity:

1.025), the true water depth in fresh water is actually 2.5% deeper than the displayed

water depth.

• Example: Water depth displayed as 20 m x 1.025 = 20.5 m (actual water depth)

WARNING

This watch cannot be used as a primary instrument for diving.

When using the watch during diving, always make sure to receive the proper

diving instruction and training and use the watch while obeying all rules.

• Inspect the watch to make sure that all functions operate properly before diving.

• It is recommended to only use this watch for recreational diving down to a depth of about

18 m. Do not attempt to dive below the limit depth of 40 m during recreational diving.

• Always make sure to allow an ample margin for no-decompression time.

• Perform adequate safety stops and decompression stops. Even in the case of no-

decompression diving, always make a safety stop at 5 m to ensure safety. In addition, in

the case the decompression stop display appears, try to stop for a period longer than

that indicated on the display.

• Allow for a sufficient rest period after diving in accordance with safety rules. Boarding an

airplane or moving to a high altitude without allowing for a sufficient rest period after

diving results in the risk of decompression sickness.

PROHIBITED Prohibited Use During Diving

Never attempt to use this watch for diving under the following circumstances.

• When diving is prohibited in the system monitor mode:

··· The watch will not switch to the dive mode when [ ] has changed to NG.

• When the watch has stopped running or an error has occurred (be careful not to bump

the watch against hard objects such as equipment or rocks when diving).

• When measuring depth outside the guaranteed water temperature range or at high

altitudes:

··· The temperature range in which the water depth measurement accuracy of this watch

is guaranteed is +10 to +40°C.

··· This watch is not compatible with diving at high altitudes. Never use this watch when

diving at high altitudes (300 m or more above sea level).

• When engaged in dangerous behavior or when a situation is judged to be dangerous:

··· This watch is not built to function as a preventive or emergency instrument such as for

use during marine accidents.

• When using in a helium gas atmosphere (saturation diving, etc.):

··· Use under these conditions can cause a malfunction or damage to the watch.

• Use for nitrox diving:

··· This watch cannot be used for diving using a mixed gas other than that of air tanks for

ordinary air diving.

WARNING Cautions Regarding Use During Diving

• Sufficiently charge the watch and confirm that the watch is reliably charged and that the

watch can be used for diving by referring to the system monitor mode. If the watch is not

sufficiently charged, the watch will not switch to the dive mode even if diving is started.

In addition, try to start a dive after first sufficiently charging the watch before diving to

avoid having the watch become insufficiently charged while diving.

Other Convenient Functions

•This watch is also equipped with a travel time function that enables you to easily display

local time when traveling or on business overseas, as well as a destination timer

About 60% charged to fully charged

Nearly insufficiently charged. Charge

the watch promptly. Since the watch

may become insufficiently charged

during diving, charge the watch

sufficiently before diving.

About 10-20% charged

Insufficiently charged. The watch cannot

be used for diving. Charge the watch

immediately.

* The above illustration provides a

graphic representation of the

amount of residual charge in the

secondary battery and the changes

in the battery charge indicator.

An approximate indication of the amount of charge remaining in the secondary battery can

be confirmed on the display. The battery charge indicator can be displayed in either the

time mode of the standard mode (location display) or the system monitor mode.

1. How to Read the Battey Charge Indicator

The battery charge indicator changes in the manner shown below according to the amount

of elapsed time the watch has been used.

2. Continuous Usage Time

This watch will continue to run for about 1 month (until the insufficient charge warning

function is activated) once it has been fully charged.

This is roughly based on the conditions of use indicated below.

• Diving (water depth measurement): Twice/week (30 min./dive)

• Alarm: 30 seconds/day

• Chronograph measurement: 1 hour/week

• EL light: 4 seconds/day

* The continuous usage time of the watch becomes shorter the more often the alarm,

chronograph and other functions are used. In addition, the continuous usage time is further

reduced by infrared communication.

* Since the water sensor is activated when the watch gets wet even when not diving, the

continuous usage time becomes correspondingly shorter.

This indicates whether or not the garbage collection operation can be performed.

* This watch uses flash memory to store the various setting and diving data of the watch edited

with a personal computer. Whenever new data is recorded in flash memory, areas of memory

that are no longer used as well as areas of memory in the gaps between files are generated in

the flash memory. Garbage collection refers to an operation that creates continuous areas of

available memory so that these areas can be reused automatically.

: Diving Function

This indicates whether or not the watch can be used for diving.

* When "NG" is displayed, the watch will not switch to the dive mode. The watch can therefore

not be used for diving in this state.

* Refer to the section on " Data Communication Functions" in this manual along with the "CAPgm"

instruction manual contained on the CD-ROM provided for further details.

Locations Pre-registered in this Watch

The following locations are registered in the watch when using the watch for the first time

(default status) or after having formatted flash memory. The following locations are

displayed in alphabetical order (except for UTC which is the first location shown) in the

correction state of each mode.

Location "IrWW"

In the case the time difference (time difference from UTC) of a location of the time mode of

the transmitting watch is not present in the receiving watch during transfer of time setting

data between watches using the infrared communication function, "IrWW" is temporarily

displayed in the location display of the receiving watch.

* Refer to section "4. Data Communication Between Watches" of " Data Communication Functions"

in this manual.

C. Flash Memory Status Display

This display provides a general indication of the amount of flash memory available. In

addition, garbage collection can also be performed during this display by pressing one of

the buttons.

a: Black segment: Area in which data has been written

and then deleted.

The area corresponding to this segment is transformed

into available memory by performing garbage collection.

b: Gray segment: Area currently used by files.

This segment becomes larger the greater the amount of

diving data, daily graphic data and so forth.

c: White segment: Area of available memory.

D. Garbage Collection Operating Procedure

Garbage collection begins when button (C) is pressed for at least 2 seconds during the

flash memory status display.

• During the garbage collection operation, an alarm sounds and "G.C." is displayed on the

display. When garbage collection is completed, "Done" is displayed on the display.

• Garbage collection cannot be performed when "G.C." has changed to "NG" on the

battery charge indicator or when the water sensor has been activated. "Fail" is displayed

on the display at this time.

Try to perform garbage collection when the black segment on the flash memory status display is

larger than the white segment (available memory). Garbage collection consumes considerable

power. For this reason as well, in order to ensure that flash memory is used efficiently, it is

recommended to perform garbage collection whenever the watch is charged (fully charged).

* In the case "Error" is displayed during the garbage collection operation, there may be an error in

the flash memory. After formatting flash memory by referring to the section on " Formatting

Flash Memory", try repeating the garbage collection operation. If "Error" is still displayed, this

indicates that the watch has malfunctioned. Please contact a Citizen Consumer help desk or

your nearest Customer Support Center to request repairs.

* Garbage collection is only performed to organize the contents of flash memory. There is no

risk of deleting watch settings or diving logs as a result of performing garbage collection.

When the watch has switched to the file error warning display, perform the garbage collection

procedure in the system monitor mode of the standard mode. The display returns to normal

following completion of garbage collection.

Abnormal Pressure Detection Error Warning

When abnormal atmosphere pressure is detected during use on land, or

when ascending to high locations more than 4000 m above sea level,

"ERR" (Error) flashes in the lower left corner of the display. The watch

does not switch to the dive mode even if the water sensor gets wet

while this warning function is activated.

If "ERR" does not disappear from the display even after a long period of time, there may be a

problem with the pressure sensor. When this happens, discontinue using the watch and consult

a Citizen Consumer help desk or your nearest Customer Support Center.

Water Sensor Check Warning

If the preliminary dive display continues to be displayed for more than 1

hour after the water sensor has gotten wet and the watch has switched

to the preliminary dive display in the dive mode, "CHK" (Check) flashes

in the lower left corner of the display to inform the wearer that the water

sensor should be checked.

* "CHK" also flashes when the watch returns to the normal display from any of

the correction states, when the watch is returned to the time mode of the

standard mode from the infrared communication mode, and when the water

sensor is operating during the all reset procedure.

The watch does not switch to the dive mode (water depth measurement display) when "CHK" is

flashing.

To check the sensor, remove any debris or moisture from the water sensor with a dry cloth. The

display returns to normal when the water sensor is canceled.

Ascent Rate Warning

When the ascent rate during scuba diving exceeds 18 m/min, the

ascent rate warning alarm sounds for 5 seconds and "SLOW" and an

illustration of a turtle are displayed at the bottom of the display.

The ascent rate warning alarm stops sounding when a proper ascent

rate is resumed.

* The ascent rate warning alarm does not sound during skin diving (continuous

diving for less than 3 minutes at a depth of 1 m or more).

Abnormal Depth Warning

When a sudden change in depth of more than 4 m/sec is detected

during diving, the watch assumes that the watch has reached an

abnormal depth. At this time, "ERR" and the diver mark are alternately

displayed in the lower left corner of the display.

Once "ERR" has been displayed during diving, it continues to be

displayed until the dive mode is terminated.

CAUTION

Avoid using the watch in environments where sea bottom drilling equipment or similar

machinery is in use. The vibrations from such equipment may cause a change in water

pressure of "4 m or more per second" to be locally and momentarily applied to the pressure

sensor of the watch, causing "ERR" to be displayed and preventing water depth from being

displayed correctly.

This watch is equipped with various warning functions for the purpose of avoiding risks and

problems when diving as much as possible.

WARNING

* Do not dive in a manner that activates any of the warning functions. Since the degree of

risk varies according to experience, physical condition and diving conditions, do not

assume that diving is completely safe just because none of the warning functions are

activated. Please use the warning functions as a general indicator of diving safety.

Insufficient Charge Warning

When the watch becomes insufficiently charged, "BATT" flashes in the

lower left corner of the display in all of the sub-modes of the standard

mode. Operation of the following functions is limited while this warning

function is activated.

• The watch does not switch to the dive mode even if the water sensor

gets wet. (The watch automatically switches to the battery charge

indicator display of the system monitor mode when the water sensor

gets wet.)

• None of the alarms sound.

• Data cannot be transferred by infrared communication. (However, data can be transmitted to

a personal computer by USB communication.)

• The EL light is not illuminated.

When this warning function is activated, charge the watch by attaching to the communication

unit as soon as possible. The display will return to normal once the watch is sufficiently

charged.

* None of the dive alarms sound when the insufficient charge warning function is activated during

diving. Although the dive computer will function normally for about 30 minutes after "BATT" starts to

flash, the log data for that dive is not recorded. Promptly begin to ascend it this warning function is

activated during diving.

* If the watch remains insufficiently charged after the insufficient charge warning function has been

activated, it switches to the low power mode after about 2 days. Please note that if the watch

continues to be left uncharged in the low power mode, all functions stop and all watch settings return

to the initial (default) settings.

File Error Warning

When the amount of available memory in flash memory becomes low,

"FILE" flashes in the lower left corner of the display in all of the sub-

modes of the standard mode as well as in the dive mode. The watch

automatically switches to the flash memory status display of the system

monitor mode when the water sensor gets wet while this warning function

is activated. Please note that although it is possible to use the watch for

diving in this state, log data may not be recorded in flash memory during

diving.

The file error warning function is also activated and additional log data is not recorded if the

duration of a single dive exceeds 2 hours or if more than 15 dives are made in a single day. The

file error warning function may also be activated when the water temperature during diving is low.

It may not be possible to receive watch settings by data communication while the file error warning

function is activated.

Flashing

The following provides an explanation of the diving terms displayed by this watch along

with their basic meanings.

This watch employs the calculation formula of the Canadian Defense and Civil Institute of

Environmental Medicine (DCIEM).

This watch automatically distinguishes between skin diving and scuba diving according to

the following conditions, and records log data separately for each type of diving.

• Scuba diving: Continuously diving for 3 minutes or more to a depth of 1 m or more

• Skin diving: Continuously diving for less than 3 minutes to a depth of 1 m or more

In this watch, one dive constitutes the time from initially diving to a depth of 1 m (start of

dive) from the preliminary dive mode state to the time the dive mode is terminated (end of

dive).

<No-Decompression Diving and No-Decompression Limit (NDL) Time>

No-decompression diving refers to diving that allows the diver to ascend to the surface

without stopping for decompression during the course of ascending following completion

of a dive. The limit time during which this no-decompression diving is allowed is referred

to as the no-decompression limit time. No-decompression limit time varies according to

the diving depth and diving time of the previous dives.

Safety stop refers to a temporary stop made during ascending for safety reasons in order

to promote expulsion of nitrogen in the body, and is performed even if the no-

decompression limit time has not been exceeded. In the case of having dove to a depth of

18 m or more, a safety stop should always be made at 5 m of depth to ensure safety.

This refers to diving beyond the no-decompression limit time. Decompression diving is

extremely dangerous since nitrogen accumulates in the body beyond allowable levels.

Never dive in this manner.

This refers to a stop that must be made to ensure the necessary decompression in the

case of having performed decompression diving. It is necessary to make a

decompression stop at a predetermined depth (decompression stop instructed depth) and

predetermined time (decompression stop instructed time) when ascending.

This refers to the minimum time required to ascend to the surface from the current depth in

the case of ascending at the rate of 18 m/min or less while making a decompression stop in

accordance with the decompression stop instructions during decompression diving.

Decompression Diving Warning

This alarm sounds for 3 seconds and the decompression stop

indicator (STOP) is displayed on the display when the no-

decompression limit time has been exceeded resulting in

decompression diving during the course of diving.

The display returns to the no-decompression diving display when

decompression stop is performed in accordance the decompression

stop instructions.

Exceed Maximum Depth Warning

When the limit depth of 40 m for recreational diving is surpassed

during the course of diving, an exceed maximum depth error

occurs, the current depth flashes and the alarm sounds for 15

seconds. During diving at a depth greater than 40 m, the warning

alarm sounds for 15 seconds every minute.

This warning function is canceled when the depth returns to 40 m or

less.

Permanent Error Warning

The instructed depth flashes and an alarm sounds continuously

when either of conditions 1 or 2 below are met. If hazardous diving

or ascending is continued while ignoring this warning, a permanent

error (ERROR) occurs:

1. When not ascending to the instructed depth and continuing to

dive at an excessively low depth (diving at which the instructed

decompression stop depth exceeds 9 m.) even though having

been instructed to make a decompression stop (Permanent Error

Warning 1).

The warning stops when the diver begins to ascend immediately and the

decompression stop instructed depth reaches 9 m or less.

2. When having ascended to a depth 1 m or more less than the instructed depth after

having been instructed to make a decompression stop (Permanent Error Warning 2).

In this case, the warning is canceled when the diver returns to the instructed depth.

If hazardous diving or ascending is continued even after the

permanent error warning function has been activated, a permanent

error results, "ERROR" appears on the display and the entire

display flashes.

When a permanent error has occurred, the next dive cannot be

made for 24 hours. (The water depth measurement function does

not operate for 24 hours. In addition, "ERROR" is displayed when

the watch is switched to the dive plan mode, and the no-

decompression limit time is not displayed.)

110 111

Flashing

This mode is used to plan the next dive. In this mode, the no-decompression limit time

according to the first dive and repetitive dives can be displayed, and dive alarms can be

set.

1. Switching the Display

The display switches between the "Dive Plan Display" and "Dive Alarm Display" each time

button (A) is pressed in the dive plan mode.

* The watch automatically returns to the time mode of the standard mode when none of the

buttons are pressed for about 3 minutes in the dive plan mode.

2. Calling Up No-Decompression Limit Time

(1) The no-decompression limit time corresponding to a depth of 12

m is displayed when button (B) is pressed during the dive plan

display.

(2) No-decompression limit times can be called up in order for every

3 m of depth each time button (B) is pressed. Repeatedly press

button (B) until the depth corresponding to the depth you plan

on diving at is displayed.

* No-decompression limit time varies according to the dive depth, dive

time of the previous dive and surface interval time from previons

dives.

Indicated Depth

This watch displays no-decompression limit time for the following 12 depths:

12 m, 15 m, 18 m, 21 m, 24 m, 27 m, 30 m, 33 m, 36 m, 39 m, 42 m, 45 m

WARNING

In order to ensure safe diving, dive while allowing an adequate margin of safety

relative to the displayed no-decompression limit time.

This refers to the amount of nitrogen dissolved in the body as a result of diving. This

watch displays a general indicator of the amount of nitrogen dissolved in the body in the

form of a bar graph. The higher the level of the black portion of the graph, the greater the

body nitrogen level.

This indicates the total number of dives for scuba diving.

* Arbitrarily resetting the number of past dives with the “CAPgm” software provided before using the

watch for diving enables this to display the total number of scuba dives made throughout your life.

This is the date (year, month and date) on which a dive was made.

This is the number of dives made in one day. A maximum of 15 dives are counted per day

for skin diving and scuba diving, respectively.

* This indicates the number of a dive for a particular dive date.

The counter is reset to 1 when the day changes.

This refers to the elapsed time following completion of scuba diving (surface interval time

(S.I. Time)). This watch measures surface interval time up to a maximum of 24 hours.

* S.I. Time as referred to in the scuba log mode represents the elapsed time from completion of the

dive of the previous log until the start of the dive of the current log.

This is the total time at a depth of 1 m or more during a single dive.

* Measurement of dive time starts when first going below a depth of 1 m, and stops when depth

reaches less than 1 m. However, if a dive is resumed to a depth of more than 1 m within 10

minutes from the time measurement of dive time stopped, dive time is continued to be measured

from the time measurement stopped.

This is the time when the depth exceeds 1 m for the first time during the dive.

This is the minimum water temperature encountered during the course of a single dive.

This is the depth when having dove the deepest during the course of a single dive.

This is the average depth during the course of a single dive.

* This refers to the average value of depth measured for every 5 seconds of dive time.

The watch displays a simple graph of the changes in depth during a dive.

* Data relating to depths measured every 5 seconds and water temperature measured every 5

minutes can be confirmed on a personal computer.
