PATENT NOTICE

U.S. Patents have been issued, or applied for, to protect the following design features:

Dive Time Remaining (U.S. Patent no. 4,586,136), Data Sensing and Processing Device (U.S. Patent no. 4,882,678),

and Variable Ascent Rate Indicator (U.S. Patent no. 5,156,055). User Setable Display (U.S. Patent no. 5,845,235) is

owned by Suunto Oy (Finland).

DECOMPRESSION MODEL

The programs within the Versa simulate the absorption of nitrogen into the body by using a math-

ematical model. This model is merely a way to apply a limited set of data to a large range of experi-

ences. The Versa dive computer model is based upon the latest research and experiments in decom-

pression 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.

FEATURES and DISPLAYS

WARNING: Prior to diving with the Versa, yo

m st also read and nderstand the Oceanic Dive

Comp ter Safety and Reference Man al which pro-

vides Important Warnings and Safety Recommen-

dations as well as general prod ct information.

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 instruc-

tional guide is intended to help you become familiar with the functions and features avail-

able and show you examples of displays that you could expect to see in the various op-

erational 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 im-

portant. Technology is no substitute for common sense, and a dive computer only pro-

vides 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.

VERSA

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, seg-

ments 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 simul-

taneously 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 pos-

sible 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.

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).

Fig. 3 - Depth Displays

Fig. 4 - Time Displays

VERSA

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

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 diagnos-

tic check then the Battery icon will flash once per second for 5 seconds (Fig. 5) 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 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 oc-

curs 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'. Fig. 5 - Low Battery Condition
