DECOMPRESSION MODEL

The programs within the Versa 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 dive computer model is based upon the latest research and experiments in decom­pression theory. Still, using the Versa, just as using the U.S. Navy (or other) No Decom-

pression 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.

WELCOME TO OCEANIC AND THANK YOU FOR CHOOSING THE VERSA !

Your Versa presents the information that you need before, during, and after your Air
dives using a combination of easy to read displays and identification icons. This instruc­tional guide is intended to help you become familiar with the functions and features avail­able and show you examples of displays that you could expect to see in the various op­erational modes. Relax and read through the complete operating manual.

Remember that the rules you learned in your basic scuba certification course(s) still apply
to the diving you will do while using a dive computer - some will become even more im­portant. 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.

CONTROL BUTTON (Fig. 1)

• The Control Button is first used to Activate the Versa.

• Once activated (and while on the surface), pressing it
momentarily provides you access to the Log Mode.

• Pressing it for several seconds provides access to the
Set Mode which allows you to set Units of measure,
Hour Format, Time of Day, and Water Activation, which
are described later.

TISSUE LOADING BAR GRAPH (TLBG)

The TLBG (Fig. 2a) represents tissue loading of nitrogen,
showing your relative no decompression or decompression
status. As your depth and elapsed dive time increase, seg­ments add to the TLBG, and as you ascend to shallower
depths, they will begin to recede, indicating that additional
no decompression time is allowed for multilevel diving.

The TLBG monitors 12 different nitrogen compartments simul­taneously and displays the one that is in control of your dive.
It is divided into a green No Decompression (normal) zone,
a yellow Caution zone (also No Decompression), and a red
Decompression (danger) zone.

VARIABLE ASCENT RATE INDICATOR (VARI)

The VARI (Fig. 2b) 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 VARI represent two sets of speeds
which change at a reference depth of 60 feet (18
meters). Refer to the chart for segment values.

• At depths greater than 60 feet (18 meters), the VARI will
flash as a warning when an ascent exceeds 60 fpm (18
mpm). At depths of 60 feet (18 meters) and shallower, it
will flash if the ascent rate exceeds 30 fpm (9mpm).

INFORMATIONAL 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.

Depth Displays

• During a dive, the Current Depth display (Fig. 3a), in-

dicates depths from 0 to 330 feet (99.9 meters) in 1 foot
(.1 meter) increments.

• By pressing the Button, the Maximum Depth reached

during that dive will also be displayed (Fig. 3b).

• During a Decompression Dive, the required Ceiling
Stop Depth is displayed in place of Maximum Depth
which can be viewed by pressing the Button.

c

Time Displays

• The Main Time display located in the lower portion of
the screen (Fig. 4a) is configured with large segments.

• A Secondary Time display is located in the center/
right portion of the display (Fig. 4b).

• Both displays are identified by clock icons (Fig. 4c).

Time displays are shown in hour:minute format (i.e., 1:45 represents one hour and

VERSA

forty five minutes, not 145 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).

POWER SUPPLY

The Versa 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.

Low Battery Condition

Voltage level is checked upon activation and every 10 minutes during operation.

• If a Low Battery Condition exists when the unit is activated, it will perform a diagnos­tic check then the Battery icon will flash once per second for 5 seconds (Fig. 5) fol­lowed by shutdown of the unit.

• If the button is not pressed to activate the unit prior to a
dive, and a Low Battery Condition exists, the Low Battery
icon will appear flashing as a warning upon descent past
5 feet (1.5 m). No other information will be displayed.

• If the unit did not display the Low Battery icon 'prior to'
entering the Dive Mode, and a Low Battery Condition oc­curs during the dive, the Low Battery icon appears after
the dive when the unit enters Surface Mode. There will
be sufficient battery power to maintain unit operation for
the remainder of 'that dive'.

ACTIVATION and SETUP

11

ACTIVATION

To Activate the Versa press and release the Button.

Backup Activation (only if Water Activation is set ON)

As a backup, the Versa will also automatically activate by water contact. This is accom­plished by bridging the gap between contacts located on the Button stem and back of the
case. The graphic H2O that will be displayed as an indication is described later.

• Upon activation, the unit will enter Diagnostic Mode (Fig. 6), displaying all segments
of the LCD (as 8's), followed by dashes (- -), then a countdown from 9 to 0. Diagnos­tic Mode checks the display functions and battery voltage to ensure that everything is
within tolerance and functioning properly.

• 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 m) or higher, it will

recalibrate itself to measure depth in feet of fresh water
instead of feet of sea water.

WARNING: If the unit is activated at elevations higher
than 14,000 feet (4,267 meters), it will perform a diagnos­tic check followed by immediate shutdown.

If no dive is made within 2 hours after initial activation,
the unit will automatically deactivate. If the wet contacts
are still bridged, the unit will reactivate and display the

Fig. 6 - Diagnostic Mode

H2O graphic.

12

SURFACE SEQUENCE

Immediately after completing its' Diagnostic check, the Versa
will automatically scroll through the following Sequence --

• Time of Day (displayed for 3 seconds), then -

• Surface Mode (displayed for 3 seconds), then -

• Time to Fly (displayed for 3 seconds only after a dive is

made, see page 31), then -

• Pre Dive Planning Sequence (each depth/time is dis-

played for 3 seconds), then -

• The Surface Sequence repeats for 2 hours, or until a dive

is made.

• Log and Set Modes can be accessed during the Surface

Sequence with the Control Button. This is described later.

Time of Day and Surface Mode (F i g. 7 )

Displayed are -

• Dive Number ('0' if no dive made yet)

• Time of Day (for 3 seconds), then -

• Elapsed Surface Time (with flashing colon) and icon (for

3 seconds)

• Tissue Loading Bar Graph (only after a dive is made)

NOTE: If the wet contacts are bridged, the graphic
'H2O' will appear in place of the dive number '0' (Fig.

8). After the unit is rinsed and dried, '0' will replace
'H2O'.

Pre Dive Planning Sequence (PDPS) (Fig. 9)

The PDPS provides a sequence of theoretical dive times avail­able for depths ranging from 30 feet (9 meters) to 160 feet
(48 meters) in 10 foot (3 meter) increments.

No decompression times are only displayed for depths
where there is at least 3 minutes of theoretical dive time
available at the depth, taking into account a descent rate of
120 feet (36 meters) per minute.

The PDPS should be reviewed prior to every dive to help you
plan your dive as required to avoid exceeding no decom­pression limits. For repetitive dives, it indicates adjusted
dive times that are available for the next dive, based on re­sidual nitrogen following the last dive and surface interval.

WARNING: The available dive times provided by the
PDPS are only predictions. Depending on cylinder
size and breathing gas consumption you may have
less time available than indicated because of breath­ing gas quantity or other limitations.

DIVE MODE BAR GRAPHS

As your depth and elapsed dive time increase, the Tissue
Loading Bar Graph (TLBG) will fill with segments (green

toward red) to represent the absorption of nitrogen (Fig.
15a). While ascending to shallower depths, the segments
that have filled the TLBG will begin to recede, offering a
graphic representation of your multilevel diving capability.

fast you are ascending (Fig. 15b). When you exceed an as­cent rate of 60 fpm (18 mpm) if deeper than 60 feet (18m),
or 30 fpm (9 mpm) if shallower than 60 feet (18m), it will en­ter the red (Too Fast) zone and all segments plus the graphic
TOO FAST will flash (Fig. 16) until your ascent rate is
slowed.

CONTROL OF DISPLAYS

During dive modes, 3 displays of information are available.
The diver can change from one display to another as often as
desired by pressing and releasing the Button.

During No Decompression conditions, the diver can choose
how much information is displayed at a given time. The dis­play chosen will remain until the diver presses the Button to
change it.

During conditions in which cautionary type information is dis­played (e.g., Decompression, etc.), there is a Main Display
of important information relevant to the specific condition.
The diver can access another display, but it will automati­cally revert to the Main Display after 3 seconds.

NO DECOMPRESSION DIVE MODE

The Versa will enter the No Decompression Dive Mode when
you descend deeper than 5 feet (1.5 meters).

No Decompression Dive Mode - Display #1 (Fig. 17)

Information includes Current Depth, Dive Time Remaining
(and Mode icon), and the Bar Graphs.

DECOMPRESSION DIVE MODE

The Versa is designed to help you by providing a representa­tion of how close you are to entering decompression. De­compression Dive Mode activates when theoretical No De­compression time/depth limits are exceeded.

Upon entering Decompression Mode, you should begin a
safe controlled ascent to a depth slightly deeper than, or
equal to, the Required Ceiling Stop Depth indicated (Fig.
20a) and decompress for the Stop Time indicated (Fig. 20b).

b

• The UP Arrow and Deco Bar will flash if you are more
than 10 feet (3 meters) deeper than the Required Ceiling
Depth.

• Once within 10 feet (3 meters) of, and below, the Re­quired Ceiling Depth, both Arrows and the Bar appear
solid.

Decompression Dive Mode - Main Display #1 (Fig. 21)

The amount of decompression credit time that you receive
is dependent on Depth, with slightly less credit given the
deeper you are. You should stay slightly deeper than the Re­quired Stop Depth indicated until the next shallower Stop
Depth appears. Then, you can slowly ascend to, but not
shallower than that indicated ceiling Stop Depth.

VERSA

Information includes -

• Current Depth.

• Required Ceiling Stop Depth/Time.

• Total Ascent Time (Fig. 21a) - which includes Stop Times
required at all ceilings and vertical Ascent Time calcu­lated at 60 feet (18 meters) per minute at depths greater
than 60 feet (18 meters) and 30 feet (9 meters) per
minute at depths of 60 feet (18 meters) and shallower.

• Applicable Bar Graphs.

• While within 10 feet (3 meters) of, and below, the Stop
Depth, both Arrows and the Bar appear solid.

• Press the Button to view Display #2.

NOTE: While in Decompression Mode, the Versa
will automatically revert to the Main Display (#1) after
3 seconds unless the Button is pressed to view an­other display of information.

VIOLATION MODES

Violation Modes that the Versa can enter are termed - Condi­tional, Delayed, and Immediate. Permanent Violation Mode
and Gauge Mode are continuations of these.

• While in Violation Modes, the Alternate Displays previ­ously described can be accessed using the Button.

NOTE: While in Violation Modes, the Versa will auto­matically revert to the Main Display after 3 seconds
unless the Button is pressed to view another display.

Fig. 23 - Deco #3

Conditional Violation Mode

The Versa will enter the Conditional Violation Mode if you
ascend to a depth shallower (Fig. 23a) than the
Required Decompression Ceiling Stop Depth displayed

(Fig. 24b).

The Down Arrow, Deco Bar, and the Total Ascent Time dis­play will flash until you descend below the Required Stop
Depth. Also displayed will be Current Depth and applicable
Bar Graphs.

If you descend below the required decompression ceiling be­fore 5 minutes have elapsed, the Versa will continue to func­tion in Decompression Dive Mode. In this case, no off-gas­sing credit will be given, and for each minute above the ceil­ing 11/2 minutes of Penalty Time will be added to Required
Stop Time.

The added Penalty (decompression) Time will then have to be
worked off first, before obtaining off-gassing credit.

Once the Penalty Time is worked-off, and off-gassing credit
begins, required decompression Stop Depths and Time will
decrease toward zero, then the Tissue Loading Bar Graph
will recede into the yellow Caution Zone and the Versa will
revert to the No Decompression Dive Mode.

Delayed Violation Mode #1 (Fig. 25)

If you remain above the Required Ceiling Stop
Depth for 'more than 5 minutes', the Tissue Loading

Bar Graph and Total Ascent Time display will flash until you
descend below the Required Stop Depth. This is a continua­tion of a Conditional Violation.

Delayed Violation Mode #2 (Fig. 26)

The Versa cannot calculate decompression times for Stop
Depths much greater than 60FT (18M) and offers no indica­tion of how much time spent underwater would result in the
need for a greater Stop Depth.

If your Decompression obligation requires a Ceil­ing Stop Depth 'between' 60 feet (18 meters) and
70 feet (21 meters), the Tissue Loading Bar Graph will

flash. Total Ascent Time will still be displayed.

You must ascend to just deeper than, and stay as close as
possible to, 60 feet (18 meters) without causing the Total As­cent Time display to flash. When the Required Stop Depth in­dicates 50 FT/ 15 M, etc., you can ascend to those depths
and continue decompressing.

Delayed Violation Mode #3 (Fig. 27)

If you descend deeper than 330 feet (99.5
meters), the Tissue Loading Bar Graph will flash, and the

Current Depth and Max Depth displays will only indicate 3
dashes ( - - -).

Upon ascending above 330 feet (99.5 meters), the Current
Depth display will be restored, however Max Depth will only
display 3 dashes (- - -) for the remainder of that dive. The
Log for that dive will also only indicate 3 dashes (- - -) as the
Max Depth achieved.

Immediate Violation Mode and Gauge Mode

During a Dive, if a ceiling much greater than 60FT (18M) is
required, an Immediate Violation Mode will be entered.
This situation would be preceded by entering Delayed Viola­tion Mode #2, previously described. The Versa would then
operate with limited functions in Gauge Mode during the
remainder of that dive and for 24 hours after surfacing.

Gauge Mode turns the Versa into a digital instrument with­out any decompression or oxygen monitoring functions.
Only Current Depth, Max Depth, Elapsed Dive Time, and
the Variable Ascent Rate Indicator will be displayed (Fig. 28).
The full Tissue Loading Bar Graph will flash as a warning of
this condition.

• Alternate displays are not available while in Gauge
Mode.

The Versa will also enter an Immediate Violation Mode
5 minutes after reaching the surface from a dive in which a
Delayed Violation occurred.

On the surface, Gauge Mode displays the Dive Number,
Surface Interval, and the full Tissue Loading Bar Graph flash­ing (Fig. 29). It does not provide the Pre Dive Planning Se­quence or the Time to Fly feature.

The countdown timer that appears with a single dash dur­ing the Surface Sequence is only provided to inform you of
the time remaining before normal Versa operation can re­sume with full features and functions.

This condition is considered a Permanent Viola­tion, and in the event that a dive is made during
the 24 hour period, a full 24 hour surface interval
must then be served before all functions are re­stored.

The first 10 minutes is, in affect, a Transition Period during
which time the following information is displayed (Fig. 30):

Fig. 30 - Transition Period

Fig. 31 - Log Mode

30

• 'Number' of that dive (during that activation period)

• Surface Interval time (colon flashing) and icon (flashing)

• Tissue Loading Bar Graph ( indicating current nitrogen
loading)

During the Transition Period, Log Mode can be accessed.
No other modes (e.g., Fly, Plan, Set) are accessible.

To view that dive's Log

Refer to page 33 for a description of the Log Mode displays.

• Press the Button to view the first display (Fig. 31).

• Press the Button again to view the Nitrogen data screen

• Press the Button again to return to Surface Mode.

• The unit will revert to Surface Mode after 2 minutes if the
button is not pressed.

Log Data will not be stored in the unit's memory until the 10
minute Transition Period on the surface is completed.

Once 10 minutes have elapsed, the Surface Mode icon and
Surface Interval time display colon stop flashing indicating
that the Dive and Transition Period are completed, and a
subsequent descent will be considered a new dive.

If you descend during the 10 minute Transition Period, time
underwater will be considered a continuation of that dive.
The time at the surface (if less than 10 minutes) will not be
added as Dive Time.

AFTER THE TRANSITION PERIOD (THE FIRST 2 HOURS)

For the remainder of the first 2 hours after surfacing,
information will continue to be displayed as the Surface Se­quence, scrolling through Time of Day/Surface Mode/Time
to Fly/Pre Dive Planning Sequence. You will have full access
to Log Mode and Set Mode.

Time to Fly

The Time to Fly Countdown Timer begins counting down 10
minutes after surfacing from a dive (after the Transition Pe­riod) displaying the word 'FLY' and a countdown that begins
at 23:50 (Fig. 32) and counts down to 0:00 (hr:min).

32

• If a violation occurred during the dive a single dash ( - )
will appear instead of the letters FLY (Fig. 33).

The Time to Fly counter is provided to assist you with decid­ing when enough surface time has elapsed to fly (or travel to
higher elevations).

• After a surface interval of 12 hours, you may choose to
fly (or travel to higher elevations), provided that your dive
profile(s) did not enter decompression. If your diving in­volved decompression or a repetitive, multi day profile, it
is strongly recommended that you wait a full 24 hours af­ter your last dive to add a greater degree of protection.

Pre Dive Planning Sequence (PDPS)

After a dive, the PDPS provides 'adjusted' No Decompres­sion Limits (Fig. 34) based on residual nitrogen calculated to
be remaining from the previous dives.

Log Mode

Information from up to 9 dives is stored in the Log for view­ing. Each subsequent dive will then overwrite the oldest dive
stored in the Log. It is therefore suggested that you transfer
the Log's data to your log book at the end of each day of div­ing. The first dive conducted after each Activation will be
#1, therefore there may be multiple #1 dives in the Log.

Dives are displayed in a reverse sequence that starts with the
dive most recently recorded, back to the oldest of the dives
stored. The most recent dive will always be the first shown in
the sequence. Each dive has 2 Log screens - Dive Number/
Time of Day started and Dive Data. Log data will not be lost
when the battery is removed/replaced, however, factory ser­vice and calibration will delete the data.

To access Log Mode (Fig. 35) -

• Press the Button momentarily while the unit is scrolling
through the Surface Sequence.

• The first screen of the most recent dive conducted will ap­pear displaying -

• Log Mode icon

• Dive Number (for that activation period)

• Time of Day (that the dive started)

• Press the Button momentarily to view the Second Screen.

• To return to the Surface Sequence at any time while in
Log Mode, press the Button for 4 seconds, releasing it
when the current Time of Day appears.

• The unit will automatically revert to the Surface Sequence
after 2 minutes if the Button is not pressed to view an­other Log Screen.

AFTER THE FIRST 2 HOURS

Two hours after the last dive the Surface Sequence will no
longer be displayed. The Time to Fly countdown (Fig. 37)
will be displayed continuously until it counts down to 0:00
(hr:min) or another dive is made.

To access other modes or enter settings -

• Press the Button to reactivate the Surface Sequence.

• The unit will again revert to the Time to Fly countdown af­ter 2 hours, if the Button is not pressed.

VERSA

WARNING: Prior to diving with the Versa, you
must also read and understand the Oceanic Dive
Computer Safety and Reference Manual which pro­vides Important Warnings and Safety Recommen­dations as well as general product information.
____________________________________________

DO NOT attempt to change the Battery during the
first 10 minutes after surfacing from a dive. Doing
so will result in loss of calculated data for repetitive
dives.

GENERAL

35

WET CONTACTS

If the graphic H2O appears during the Fly Mode countdown
(Fig. 38), it is an indication that the water activation contacts
are bridged (still wet) and the unit must be rinsed in fresh wa­ter and thoroughly dried.

• Once the unit is dry, the graphic H2O will disappear
from the display (Fig. 39).

Fig. 38 - Activation Contacts Wet

Fig. 39 - Activation Contacts Dried

36

• If the unit is not cleaned and dried prior to the count­down reaching 0:00 (hr:min), or making another dive, it
will shut off then automatically reactivate. The graphic
H2O would then appear in place of Dive Number when
Surface Mode is displayed during the scrolling Surface
Sequence. If no dive is made, the unit would shut off af­ter 2 hours, then automatically reactivate again, repeat­ing the action until cleaned and dried.

CARE AND CLEANING

Protect your Versa from shock, excessive temperatures such
as the trunk of a car during a hot day, chemical attack, and
tampering. Protect the lens against scratches with a transpar­ent Instrument Lens Protector. Small scratches will naturally
disappear underwater.

Soak and rinse the Versa in fresh water at the end of each
day of diving, and check to ensure that the areas around the
low pressure (depth) sensor (Fig. 40a) and button are free of
debris or obstructions. To dissolve salt crystals, use luke­warm water or a slightly acidic white vinegar/water bath.
After removal from the bath, place the unit under gently run­ning water and towel dry before storing. Transport your unit
cool, dry, and protected.

INSPECTIONS AND SERVICE

Your Versa should be inspected annually by an Autho­rized Oceanic Dealer who will perform a factory prescribed
function check and inspection for damage or wear. To keep
the 2 year limited warranty in effect, this inspection must be
completed one year after purchase (+/- 30 days).

Oceanic recommends that you continue to have this inspec­tion performed every year to ensure it is working properly.
The costs of annual inspections are not covered under the
terms of the 2 year limited warranty.

It is possible to damage the depth sensor of the Versa if it is
not pressure tested properly. Ensure that your Versa is never
pressure tested unless completely immersed in water.

BATTERY REPLACEMENT

The battery compartment should only be opened in a dry and
clean environment with extreme care taken to prevent the
entrance of moisture or dust.

As an additional precautionary measure to prevent formation
of moisture in the battery compartment, it is recommended
that the battery be changed in an environment equivalent to
the local outdoor temperature and humidity (e.g., do not
change the battery in an air conditioned environment then
take it outside during a hot sunny day).

Module Removal from Boot

• DO NOT use tools or lubricants. Doing so could dam­age the module or boot.

• Use care not to drop the module when it dislodges from
the boot.

• Turn the unit over so the back is facing you.

• Using the fingers of your left hand, lift and pull the top
(upper/front portion) of the Boot back toward you while
simultaneously pressing the top (upper/right portion) of
the module away with your right thumb (Fig. 41).

• Press firmly until the upper/right tab of the module slides
of the retaining lip inside the boot.
