DECOMPRESSION MODEL
The programs within the Versa Pro simulate the absorption of nitrogen into the body by using a
mathematical model. This model is merely a way to apply a limited set of data to a large range of
experiences. The Versa Pro dive computer model is based upon the latest research and experiments in
decompression theory. Still, using the Versa Pro, just as using the U.S. Navy (or other)
No Decompression Tables, is no guarantee of avoiding decompression sickness, i.e.
“the bends.” Every diver’s physiology is different, and can even vary from day to day. No machine
can predict how your body will react to a particular dive profile.

INTRODUCTION
Welcome to Oceanic and thank you for choosing the Versa Pro !
It is extremely important that you read this Operating Manual in sequence and understand it
completely before attempting to use the Versa Pro.
It is equally important that you read the Oceanic Dive Computer Safety and Reference
Manual provided with your Versa Pro. It contains information that you must become
familiar with prior to diving with your Versa Pro.
Remember that technology is no substitute for common sense, and a dive computer only
provides the person using it with data, not the knowledge to use it.
INTERACTIVE CONTROL CONSOLE
The Interactive Control Console consists of two Control
Buttons which allow you to select display options and access
specific information when you want to see it. They are also
used to enter settings, activate the Backlight, and acknowl-
edge the Audible Alarm.
The Front button is referred to as Advance (Fig. 1a) and
the Side button as Select (Fig. 1b).

BAR GRAPHS
Tissu Loading Bar Graph (TLBG)
The Tissue Loading Bar Graph (Fig. 2a) represents tissue
loading of nitrogen, showing your relative no decompression
or decompression status. As your depth and elapsed dive time
increase, segments will add to the Graph, and as you ascend
to shallower depths, the Bar Graph will begin to recede,
indicating that additional no decompression time is allowed for
multilevel diving.
The Tissue Loading Bar Graph monitors 12 different nitrogen
compartments simultaneously and displays the one that is in
control of your dive. It is divided into a green No Decompres-
sion (normal) zone, a yellow Caution zone (also No Decom-
pression), and a red Decompression (danger) zone.
While you cannot provide a guarantee against the occurrence
of decompression sickness, you may choose your own per-
sonal zone of caution based upon age, physique, excessive
weight, etc., to reduce the statistical risk.
NOTE: Displays associat d with oxyg n and th O2
Bar Graph will only app ar if FO2 has b n s t at a
valu oth r than 'Air' ( .g., a num rical valu ). Fig. 2 - TLBG
a

10
Oxyg n Accumulation Bar Graph (O2BG)
The O2 Bar Graph (Fig. 3a) represents oxygen loading,
showing the maximum of either per dive accumulated oxygen,
or 24 hour period accumulated oxygen.
As your oxygen exposure (accumulation) increases during the
dive, segments will add to the Bar Graph, and as loading
decreases, it will begin to recede, indicating that additional
exposure is allowed for that dive and 24 hour period.
Variabl Asc nt Rat Indicator (VARI)
The Variable Ascent Rate Indicator (Fig. 3b) provides a visual
representation of ascent speed (i.e., an ascent speedometer).
Green is a 'normal' rate, yellow a 'caution' rate, and red is
'Too Fast'.
The segments of the Variable Ascent Rate Indicator represent
two sets of speeds which change at a reference depth of 60
feet (18 meters). Refer to the chart for segment values.
WARNING: At d pths gr at r than 60 f t (18
m t rs), asc nt rat s should not xc d 60 f t p r
minut (18 m t rs p r minut ). At d pths of 60 f t
(18 m t rs) and shallow r, asc nt rat s should not
xc d 30 f t p r minut (9 m t rs p r minut ).

ALPHA / NUMERIC DISPLAYS
Each numeric and graphic display represents a
unique piece of information. It is imperative that
you understand the formats, ranges, and values of
the information represented to avoid any possible
misunderstanding that could result in error.
D pth Displays
During a dive, the Current Depth display (Fig. 4a), indicates
depths from 0 to 330 feet (99.9 meters) in 1 foot (.1 meter)
increments.
By pressing the Advance (Front) button, the Maximum
Depth reached during that dive will be displayed in the
center/left portion of the display (Fig. 4b).
• When the unit is set to operate as a digital depth gauge/
timer (referred to as User Set Gauge Mode), the Depth
Display range is 'extended' to 399 feet (120 meters). At
depths greater than 99.9 meters it will indicate metric
values in increments of 1 meter.
During a Decompression Dive, the required Ceiling Stop
Depth is displayed in the center of the screen. Maximum
Depth can be viewed by pressing the Advance (Front) button. Fig. 4 - Depth Displays
a
b

12
Tim and Dat Displays
Time displays are shown in hour:minute format (i.e., 1:16
represents 1 hour and 16 minutes, not 116 minutes!). The
colon that separates hours and minutes blinks once per second
when the display is indicating real time (e.g., Elapsed Dive
Time), and is solid (non-blinking) when times are calculated
projections (e.g., Time to Fly).
The Main Time display is located in the lower portion of the
display (Fig. 5a) and a second time display (Fig. 5b) is
located in the center/right. Both displays are identified by a
clock icon.
• Time of Day can be set for 12 hour format (Am/Pm) or 24
hour format.
Date is displayed in the center/left portion of the screen (Fig.
6a) only to identify dive data while it is viewed in the Log
Mode.
• When Units of Measure are set for 'Imperial', the Month
appears to the left of Day. When set for Metric, the Month
appears to the right of Day.

T mp ratur Display
Ambient Temperature is displayed in the center/left portion of the screen (Fig. 7a)
while in the Surface Mode and Log Mode, and can be viewed as part of an Alternate
Display when the Advance (Front) button is pressed while in a dive mode.
If the Temperature exceeds a value of '99', two dashes ( - - ) will be displayed on the screen
until the unit's temperature decreases to '99'.
NOTE: Th Informational Displays ar d scrib d in d tail as th various
op rating mod s th y app ar in ar pr s nt d throughout this manual.
AUDIBLE ALARM
LED Warning Light
A red LED Warning Light and Speaker icon are synchronized
with the Audible Alarm and will illuminate the display when the
Alarm emits a tone. They will turn OFF when the Alarm is
acknowledged, or Set OFF (a user setting).
When warning situations activate the Alarm, the unit will emit
a continuous tone for 30 seconds, or until the situation is
corrected, or it is acknowledged by pressing the Advance
(Front) button for 2 seconds. If acknowledged by the user and
the situation corrected, the Alarm will sound again upon
reentry into the warning situation, or entry into another type of
warning situation. Fig. 7 - Temperature Display

Situations that will sound th Alarm, if it is turn d ON (a us r s tting), includ -
• Entry into Decompression Mode
• PO2 => than the Max PO2 Alarm (a user setting), or => 1.60 ATA.
• Descent deeper than the Max Depth Alarm (a user setting).
• Nitrogen Bar Graph Alarm (a user setting).
• Dive Time Remaining Alarm (a use setting).
• Elapsed Dive Time Alarm (a use setting).
• O2 Accumulation => allowable per dive limit, or limit for a 24 hour period.
• Ascending above a required Decompression stop depth for less than 5 minutes (Condi-
tional Violation).
• Ascent rate exceeds 60 feet/minute (18 meters/minute) if greater than 60 feet (18
meters), or 30 feet/minute (9 meters/minute) at 60 feet (18 meters) and shallower.
During th following situations, th 30 s cond continuous ton will b follow d by a
5 s cond st ady b p that will not turn off wh n acknowl dg d, v n if it was us r
S t OFF -
• Ascending above a required Decompression stop depth for more than 5 minutes (De-
layed Violation).
• Decompression requires a ceiling stop depth of 70 feet/21 meters or deeper.
• Being on the surface for 5 minutes after a Conditional Violation (Permanent Violation).
A singl short b p (which cannot b disabl d) is mitt d for th following -
• After the Diagnostic countdown, if everything is okay.
• If the unit automatically returns to Surface Mode from Simulator Mode.
• Upon completion of a Hot Swap battery change with calculations saved.
• Change from Delayed to Full Violation 5 minutes after the dive.

15
BACKLIGHT
To activate the Backlight - press the Select (Side) button.
• On the surface, the Smart Glo® feature senses the intensity of
natural light present. If a low level of light is present, the
Backlight will activate and illuminate the display for 5 sec-
onds, or the Duration time (a user setting).
• During a dive, the Oceanglo® feature will activate the
Backlight and the display will be illuminated for 5 seconds, or
the Duration time set (a user setting).
• The Backlight does not operate during a Low Battery
condition.
• Press the button again to activate as desired.
POWER SUPPLY
The Versa Pro utilizes one (1) type CR 2450 Lithium 3 volt cell
that should provide 300 hours of continuous, or 50 activation
periods, of operation. If you conduct 1 dive each time the unit
is activated, you should obtain approximately 50 dives. If you
conduct 3 dives each time the unit is activated, you should
obtain approximately 150 dives.
Batt ry Indicator
A Battery Indicator provides an indication of battery condition.
When power is sufficient for normal unit operation, the Indica-
tor will be displayed during Surface Mode (Fig. 8a). The
Indicator will not be displayed during Dive Mode(s). Fig. 8 - Battery Indi ator
a

16
Low Batt ry Condition
Voltage level is checked upon activation and every 10 minutes during operation.
• When the unit estimates that 75 % of the Rated Power has been consumed, the lower
bar of the Battery Indicator (only segment) will be displayed, and the outline of the
Indicator will flash once per second as a warning that the battery is to be replaced prior
to conducting any further dives.
• Upon decreasing to a voltage level that will no longer sustain proper operation, the
Indicator will flash 5 times followed by shutdown of the unit.
• If a Low Battery Condition exists when the unit is activated (by pressing the button), the
graphic bAT and the Battery Indicator will appear flashing for 5 seconds (Fig. 9) fol-
lowed by shutdown of the unit.
• If the button is not pressed to activate the unit prior to a dive, and a Low Battery Condi-
tion exists, the Battery Indicator will appear flashing as a warning upon descent past 4
feet (1.2 meters). No other information will be displayed.
• If the unit did not display a Low Battery Condition 'prior to'
entering the Dive Mode, and a Low Battery Condition occurs
during the dive, there will be sufficient battery power to main-
tain unit operation for the remainder of 'that dive'. The Battery
Indicator will appear after the dive in Surface Mode.
When the Battery is removed, settings and nitrogen and
oxygen calculations for repetitive dives will be retained, if a
new battery can be inserted within 8 seconds. Otherwise the
calculations will reset to zero and settings such as Time, Date,
and FO2 must be reset.
Fig. 9 -Low Battery Condition

17
FO2 MODE
After Activation, the Versa Pro will operate as an Air computer
without displaying information associated with oxygen calcula-
tions, unless it is set for a percentage of oxygen (FO2) other
than Air (a numerical value between 21 and 50 %).
When set with an FO2 value of 'Air' (Fig. 10), the Versa
Pro will perform calculations the same as if FO2 were set for
21% oxygen, internally accounting for oxygen loading for any
subsequent Nitrox dives. However, oxygen related displays,
warnings, and the O2 Bar Graph will not appear on the
display for that dive, or subsequent dives, unless FO2 is set for
a numerical value (21 - 50).
Once a dive is made with the unit set as a nitrox computer
(FO2 set for a numerical value), it cannot be programmed to
operate as an 'Air' computer until 24 hours after the last dive.
'Air' will not be displayed as an option in the FO2 Mode.
However, you can set FO2 for 21% for use with Air.
When FO2 is set at a value of 21% (Fig. 11), the unit will
remain set at 21% for subsequent nitrox dives until FO2 is set
to a higher value, or until it automatically turns off and is
reactivated. S tting FO2 is d scrib d on Pag 23.
Fig. 10 - FO2 set for Air
Fig. 11 - FO2 set for 21%

18
Fig. 12 - FO2 Default ON
Fig. 13 - FO2 Default OFF
FO2 50% D fault
If the Default is set to ON (Fig. 12) and FO2 is set to a
value 'greater than 21%', the FO2 set point value will auto-
matically revert to 50% 10 minutes after that dive. The Maxi-
mum Depth that can be achieved with a PO2 of 1.60 ATA will
also be displayed.
• FO2 must therefore be reset for each repetitive nitrox dive,
or the value will automatically 'default' to 50(%) and the
dives will be calculated based on 50% O2 (50% nitrogen)
for oxygen calculations and 21% O2 (79% nitrogen) for
nitrogen calculations.
If the Default is set to OFF (Fig. 13), the FO2 value for
repetitive dives remains the same as previously set until the set
point is manually changed.

ACTIVATION
WARNING: If th unit is activat d at l vations
high r than 14,000 f t (4,267 m t rs), it will p r-
form a diagnostic ch ck and imm diat ly shutdown.
To Activate the Versa Pro press and release the
Advance (Front) Button.
• Upon manual activation, the unit will enter Diagnostic
Mode (Fig. 14), displaying all segments of the LCD as 8's,
followed by dashes (- -), then a countdown from 9 to 0.
Diagnostic Mode checks the display and battery voltage to
ensure that everything is within tolerance and functioning
properly.
• When the front (Advance) button is held depressed when
the Diagnostic countdown reaches 00, an External Access
request is initiated. A Serial Number screen appears
displaying the unit’s Serial Number and firmware code
Revision Number as long as the button is held depressed
(Fig. 15). Upon releasing the button, the unit shuts Off.
• After manual activation, it will also check the ambient
barometric pressure, and calibrate its present depth as
zero. At elevations of 2,000 feet (610 meters) or higher, it
will recalibrate itself to measure depth in feet of fresh water
instead of feet of sea water.
