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.
b
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 acknowledge the Audible Alarm.
The Front button is referred to as Advance (Fig. 1a) and the Side button as Select (Fig. 1b).

BAR GRAPHS
Tissue 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 Decompression (normal) zone, a yellow Caution zone (also No Decompression), and a red Decompression (danger) zone.
While you cannot provide a guarantee against the occurrence of decompression sickness, you may choose your own personal zone of caution based upon age, physique, excessive weight, etc., to reduce the statistical risk.
NOTE: Displays associated with oxygen and the O2
Bar Graph will only appear if FO2 has been set at a value other than 'Air' (e.g., a numerical value).

Oxygen 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.
Variable Ascent Rate 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 depths greater than 60 feet (18 meters), ascent rates should not exceed 60 feet per minute (18 meters per minute). At depths of 60 feet
(18 meters) and shallower, ascent rates should not exceed 30 feet per minute (9 meters per minute).
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.
Depth 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. 5 - Time Displays a b
Time and Date 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.
12
Fig. 6 - Date Display
Temperature 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: The Informational Displays are described in detail as the various operating modes they appear in are presented 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).
a
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 the Alarm, if it is turned ON (a user setting), include -
• 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 (Conditional 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 the following situations, the 30 second continuous tone will be followed by a
5 second steady beep that will not turn off when acknowledged, even if it was user
Set OFF -
• Ascending above a required Decompression stop depth for more than 5 minutes (Delayed 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 single short beep (which cannot be disabled) is emitted for the 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.
14
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 seconds, 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.
Battery Indicator
A Battery Indicator provides an indication of battery condition.
When power is sufficient for normal unit operation, the Indicator will be displayed during Surface Mode (Fig. 8a). The
Indicator will not be displayed during Dive Mode(s).
a
Fig. 8 - Battery Indicator
15
Low Battery 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) 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 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 maintain 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.
16
Fig. 9 -Low Battery Condition
FO2 MODE
After Activation, the Versa Pro will operate as an Air computer without displaying information associated with oxygen calculations, 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.
Setting FO2 is described on Page 23.
Fig. 10 - FO2 set for Air
Fig. 11 - FO2 set for 21%
17
Fig. 12 - FO2 Default ON
FO2 50% Default
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 automatically revert to 50% 10 minutes after that dive. The Maximum 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 the unit is activated at elevations higher than 14,000 feet (4,267 meters), it will perform a diagnostic check and immediately 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.

Fig. 15 - Serial Number
Backup Activation (only if Water Activation is set ON)
As a backup, the Versa Pro will also automatically activate by water contact. This is accomplished by bridging the gap between contacts located on the Button stems and back of the case. The graphic H2O that will be displayed as an indication is described later.
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 H2O graphic.
SURFACE MODE
Surface Mode (Fig. 16A), identified by the Surface Time icon, follows Diagnostic Mode after Activation. Information includes
Dive Number '0' (no dive made yet), Temperature (and icon),
Time of Day (with icon), the Battery Consumption Indicator, and Surface Time (with flashing colon).
If the wet contacts are bridged, the graphic 'H2O' will appear in place of the dive number '0' (Fig. 16B). After the unit is rinsed and dried, '0' will replace 'H2O'.

No Decompression Limits for an Air Dive
(no dive made yet)
PRE DIVE PLANNING SEQUENCE TM
Oceanic strongly recommends that you review the
Pre Dive Planning Sequence (PDPS) prior to every dive to help you plan your dive as required to avoid exceeding no decompression or oxygen exposure limits.
This is especially important for repetitive dives when the PDPS indicates adjusted dive times that are available for the next dive, based on residual nitrogen or oxygen accumulation
(whichever is in control) following the last dive and surface interval.
The PDPS provides a sequence of theoretical dive times available for depths ranging from 30 feet (9 meters) to 190 feet (57 meters) in 10 foot (3 meter) increments.
During the sequence, no decompression times are only displayed for depths where there is at least 1 minute of theoretical dive time available at the depth, taking into account a descent rate of 60 feet (18 meters) per minute.
To access the Pre Dive Planning Sequence
(while in the Surface mode) -
• Press the Advance (Front) button 1 time
• Press and release the Select (Side) button to advance through the depths/times, one screen at a time.
• Press the Advance (Front) button to access Fly Mode.
• The unit will revert to Surface Mode after 2 minutes if no button is pressed.
• With each depth displayed by the Pre Dive Planning
Sequence, you will see either predicted no decompression limits (NDLs) based upon your previous dive profiles (if calculated to be nitrogen controlled), or predicted oxygen tolerance limits (OTLs) based upon either a single dive exposure or your 24 hour accumulation of oxygen (if calculated to be oxygen controlled).
• The Maximum Depth allowed for PO2 of 1.6 (ATA) for the
FO2 setting will also be displayed.
• Depths greater than the maximum depth that can be achieved with a PO2 of 1.60 ATA will not be displayed.
• If the Tissue Loading Bar Graph is displayed (Fig. 40), that next dive is calculated to be controlled by nitrogen loading.
• If the O2BG and O2 symbol are displayed (Fig. 41), it is calculated to be controlled by oxygen loading.
Fig. 40 - Nitrogen Control

44
Fig. 42 - Tissue Loading Bar
Graph
NOTE: The Versa Pro will store oxygen accumulation calculations for up to 10 dives conducted during a 24 hour period. If the maximum limit for oxygen loading has been exceeded for that day (24 hour period), all of the segments of the O2 bar graph will be displayed flashing .
Depth/Time values will not appear until the O2 bar graph recedes into the green (normal) zone (i.e., your daily oxygen dosage decreases an amount equivalent to the amount accumulated during the latest dive completed).
TISSUE LOADING BAR GRAPH (Fig. 42a)
As your Depth and Elapsed Dive Time increase, the Tissue
Loading Bar Graph (TLBG) will add segments (green toward red) to represent the absorption of nitrogen.
While ascending to shallower depths, the number of segments displayed will begin to recede, offering a graphic representation of your multilevel diving capability.
OXYGEN ACCUMULATION BAR GRAPH (Fig. 43a)
If FO2 was set for a numerical value (nitrox), the Oxygen
Accumulation (O2) Bar Graph will add segments (green toward red) to represent oxygen accumulation for that dive, or
24 hour period, whichever amount is greater.
VARIABLE ASCENT RATE INDICATOR (Fig. 44a)
The Variable Ascent Rate Indicator (VARI) shows how fast you are ascending. When you exceed the maximum recommended ascent rate for the depth you are at (see below), it will enter the red (Too Fast) zone and you will be alerted by the graphic TOO FAST, all segments of the bar graph flashing, an Audible alarm and the red LED Warning Indicator (unless set OFF). The warnings will stop when your ascent rate is slowed.
• At depths greater than 60 feet (18 meters), maximum recommended rate is 60 feet/minute (18 meters/minute).
• At depths of 60 feet (18 meters) and shallower, maximum recommended rate is 30 feet/minute (9 meters/minute).
NOTE: Refer to page 10 for additional information pertaining to the Variable Ascent Rate Indicator.

CONTROL OF DISPLAYS
During No Decompression conditions, various displays of information (up to 4) are available. Each provides Depth, Dive Time Remaining, and additional information. The intent of this feature is to provide the diver control of how much information is on display at any given time during the dive. The diver can change from one display to another as often as desired by pressing the Advance (Front) button, otherwise it does not change.
During conditions in which cautionary type information is displayed (e.g., Decompression,
High PO2, 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.
To activate the Backlight, during a dive press the Select (Side) button.
• The displays will be illuminated as long as the button is depressed, plus it will remain illuminated for the Backlight Duration time that has been set (0, 3, or 7 seconds).
• The Backlight will not activate during a Low Battery condition.
NO DECOMPRESSION DIVE MODE
The Versa Pro will enter the No Decompression Dive Mode when you descend deeper than
4 feet (1.2 meters).

DECOMPRESSION DIVE MODE
The Versa Pro is designed to help you by providing a representation of how close you are to entering decompression. Decompression Dive Mode (Fig. 50) activates when theoretical
No Decompression time/depth limits are exceeded.
Upon entering Decompression Mode, the Audible Alarm will sound and the red LED Warning Indicator (and icon) will flash for 30 seconds (unless set OFF), or until acknowledged.
• Press and hold the Advance (Front) button for 2 seconds to acknowledge/silence the Audible Alarm (unless set OFF).
• The UP Arrow and Deco Bar will flash if you are greater than 10 feet (3 m) deeper than the Required Stop Depth.
• Once you are within 10 feet (3 m) of, and below, the Stop
Depth, both Arrows and the Bar appear solid.
Total Ascent Time
Total Ascent Time (Fig. 50a) includes Stop Times required at all required decompression ceilings and vertical Ascent Time calculated at 60 feet (18 meters) per minute for depths deeper than 60 feet (18 meters), and 30 feet (9 meters) per minute for depths of 60 feet (18 meters) and shallower.

Managing Decompression Stops
To fulfill your decompression obligation, you should make a safe controlled ascent to a depth slightly deeper than, or equal to, the Required Ceiling Stop Depth indicated (Fig. 51a) and decompress for the Stop Time indicated (Fig. 51b).
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 (Fig. 51c) 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.
• While in Decompression Mode, the Versa Pro will automatically revert to the Main Display after 3 seconds unless the Advance (Front) button is pressed to view another display of information.

VIOLATION MODES
While in Violation Modes the Alternate Displays previously described can be accessed using the Advance (Front) button, and the Backlight can be activated using the Select (Side) button.
• The Versa Pro will automatically revert to the Main
Display after 3 seconds unless the Advance (Front) button is pressed to view another display of information.
NOTE: Upon entry into Violation Modes, the
Audible Alarm will emit a 30 second continuous tone followed by a 5 second steady beep. The
Alarm will sound even if it is user Set OFF. It also cannot be turned off (acknowledged) by pressing the Advance (Front) button.
Conditional Violation Mode
If you ascend shallower (Fig. 55a) than a Required
Decompression Ceiling Stop Depth displayed (Fig. 55b), the Down Arrow, Deco Bar, and Total Ascent Time will flash until you descend below the Required Stop Depth. Also displayed will be Current Depth and applicable bar graphs.
Unless set OFF (a user setting), the Audible Alarm will emit a continuous tone for 30 seconds or until acknowledged by pressing the Advance (Front) button.
If you descend below the required decompression ceiling before 5 minutes have elapsed, the Versa Pro will continue to function in Decompression Dive Mode. In this case, no offgassing credit will be given, and for each minute above the ceiling 1 1 /
2 minutes of Penalty Time will be added to
Required Stop Time.
The added Penalty (decompression) Time will 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 Pro will revert to the No Decompression Dive Mode.
NOTE: Upon entry into Delayed Violation Modes, the red LED warning light will light and the Audible
Alarm will sound, even if it is user Set OFF. It cannot be turned off (acknowledged) by pressing the Advance (Front) button.

Delayed Violation Mode #1 (Fig. 56)
If you remain above the Required Ceiling Stop
Depth for 'more than 5 minutes', the Tissue Loading Bar
Graph and Total Ascent Time will flash until you descend below the Required Stop Depth. This is a continuation of a
Conditional Violation.
Delayed Violation Mode #2 (Fig. 57)
The Versa Pro cannot calculate decompression times for Stop
Depths much greater than 60 feet (18 meters) 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.
Fig. 57 - Delayed Violation #2
54
Delayed Violation Mode #3 (Fig. 58)
If you descend deeper than 330 feet (99.9 meters),
the Tissue Loading Bar Graph segments will flash, and the
Current Depth and Max Depth displays will only indicate 3 dashes ( - - -).
Upon ascending above 330 feet (99.9 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 display 3 dashes as the Max Depth achieved.
Immediate Violation Mode and Gauge Mode
During a Dive, if a ceiling much greater than 60 feet (18 meters) is required, an Immediate Violation Mode will be entered. This situation would be preceded by entering Delayed
Violation Mode #2. The Versa Pro 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 Pro 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. 59). The Tissue Loading Bar
Graph and O2 Bar Graph will both flash as a warning of this condition.

• Press the Advance (Front) button to view Temperature and
Time of Day.
• Press the Select (Side) button to activate the Backlight.
The Versa Pro 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,
Temperature, Time of Day, and Surface Interval (Fig. 60). It does not provide the FO2, PDPS, or Time to Fly and
Desaturate features.
The countdown timer that appears when you try to access Time to Fly does not represent 'Time to Fly'. It is only provided to inform you of the time remaining before normal Versa Pro operation can resume with full features and functions.
This condition is 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.
HIGH PO2 DIVE MODE
When partial pressure of oxygen (PO2) becomes equal to, or greater than, 1.40 ATA, or 0.2 ATA less than the PO2
Alarm set point (a user setting); the red LED warning will flash, the Audible Alarm will sound (unless set OFF), and the current PO2 value, PO2 symbol, O2 segment of the O2
Bar Graph, and UP Arrow will appear on the Main Display as a warning until PO2 decreases. Current Depth and Dive Time
Remaining will also be displayed (Fig. 61).
If PO2 continues to increase, the value displayed will increase toward a maximum value of 5.00 ATA in increments of .01
ATA. When it reaches a value of 1.60 ATA, or the PO2
Alarm set point (a user setting), the Audible Alarm will sound (unless set OFF) and the current PO2 value, PO2 symbol, O2 segment of the O2 Bar Graph, and UP Arrow will flash as a warning until PO2 decreases (Fig. 62).
• Press the Advance (Front) button to view the Alternate
Displays.
• The unit will revert to the Main Display after 3 seconds.
• Press the Select (Side) button to activate the Backlight.

HIGH OXYGEN ACCUMULATION
The O2 Bar Graph displays either oxygen accumulated during that nitrox dive, or during the repetitive nitrox dives you conduct during that 24 hour period, whichever of the two is greater at that time.
The yellow Caution Zone of the O2 Bar Graph offers you a convenient way to consistently monitor how close you are coming to the limits of oxygen exposure. Use it as a visual
reference to place a wider margin of protection between you and the Limits.
If the theoretical amount of oxygen accumulated equals, or exceeds, the limit for a single exposure, or the exposure limit for a 24 hour period, Oxygen Dive Time Remaining becomes zero (0:00) and the O2 Bar Graph will enter the red O2
(Danger) Zone (Fig. 63). The red LED warning will flash, the Audible Alarm will sound (unless set OFF), and the UP
Arrow and the full O2 Bar Graph will flash as a warning until the level of oxygen decreases below the limit.
• Press the Advance (Front) button to view the Alternate
Displays.
• The unit will revert to the Main Display after 3 seconds.
• Press the Select (Side) button to activate the Backlight.
USER SET DIGITAL GAUGE MODE
When Digital Gauge Mode is set for ON, the Versa Pro will operate as a Digital Depth Gauge/Timer without performing nitrogen and oxygen calculations (Fig. 64).
While in this mode, the range of the Current and Maximum
Depth displays are extended to 399 feet (120 meters) to accommodate activities involving diving with advanced breathing gas mixtures or free diving beyond the normal depth limit of the unit. Time of Day and Elapsed Dive Time will also be displayed.
UNEXPECTED LOSS OF DISPLAYED INFORMATION
If your Versa Pro stops working for any reason, it is important that you have anticipated this possibility and are prepared for it. This is an important reason for not pushing the
no decompression and oxygen accumulation limits, and a critical reason to avoid entering decompression.
If you dive in situations where your trip would be ruined or your safety would be jeopardized by losing the use of your
Versa Pro, a backup instrument system is highly recommended.

LOG MODE
Information from your latest 24 dives is stored in the Log for viewing. The first dive of a new Activation Period will be #1, then #2, etc. After 24 dives are accumulated, each subsequent dive will overwrite the oldest dive in the Log (i.e., the most recent dive deletes the oldest). Log information will not be lost when the battery is removed, but factory service will delete data.
Dives are displayed in a reverse sequence that starts with the dive most recently recorded back to the oldest of the 24 dives stored. Thus, your most recent dive will always be the first shown in the sequence. Each dive has three log screens - Date/Time started, Nitrogen data, and Oxygen data (not displayed if the dive included a Violation). Dives are identified by the Date/Time started and 'number' that day.
Button Control in Log Mode -
• The Advance (Front) button is used to access a specific dive's Log.
• HINT: To bypass a dive's Log and search for another in the sequence, press the Advance (Front) button repeatedly. Do not press the Select (Side) button until you find the dive Log you wish to view.

NOTE: The procedures that follow must be closely adhered to. Damage due to improper battery replacement is not covered by the unit's 2 year warranty.
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).
Inspect the Button, Lens, and Housing to ensure they are not cracked or damaged. If there is any sign of moisture in the module, DO NOT use the Versa Pro until it receives proper service by an Authorized Oceanic Dealer, or the Oceanic factory.
Hot Swap
If the new battery can be inserted within 10 seconds after the old one is removed (Hot Swap), settings and nitrogen and oxygen calculations for repetitive dives will be retained.
Battery Hatch Removal
• Locate the Battery Compartment on the back of the unit.
• While applying steady inward pressure on the clear
Battery Hatch, rotate the Hatch Ring clockwise 10 degrees by pressing on the upper/right arm of the Ring with a small blade screwdriver (Fig. 90).
NOTE: If available, an adjustable face spanner tool or a pair of pointed pliers can be used instead of the screwdriver by inserting the tips of the tool in the small holes in the Ring (Fig. 91).
• Lift the Hatch Ring up and away from the Housing.
• Remove the clear Battery Hatch.
Battery Removal
• Remove the Retaining Bar located across the lower portion of the Battery (Fig. 92a).
• Remove the Hatch O-ring. DO NOT use tools
• Using care not to damage the Battery Contacts (Fig. 92 b/ c), slide the Battery up and out of the right side of the
Battery Compartment.
NOTE: DO NOT allow a metal object to short circuit the top of the Battery which is positive (+) to the negative ( - ) contact of the Battery Compartment.

Inspection
• Closely check all of the sealing surfaces for any signs of damage that might impair proper sealing.
• Inspect the Buttons, Lens, and Housing to ensure they are not cracked or damaged.
• If it is necessary to clean the Battery Compartment, flush the it and all components with a solution of 50% white vinegar and 50% fresh water. Rinse with fresh water, and allow to dry overnight, or blow dry with a hair dryer (set at
'no heat').
WARNING: If damage, moisture, or corrosion is found, it is recommended that you return your
Versa Pro to an Authorized Oceanic Dealer, and DO
NOT attempt to use it until it has received factory prescribed service.
Battery Installation
• Slide a new 3 volt type CR2450 Lithium Battery, negative (-
) side down into the Battery Cavity. Slide it in from the right side and ensure that it slides under the contact clip on the left rim of the cavity.
• Orient the Retaining Bar across the lower portion of the
Battery and carefully push it down into position (Fig. 93).
Battery Hatch and Hatch Ring Installation
• Replace the Hatch O-ring with a new one. This O-ring must be a genuine Oceanic part that can be purchased from an Authorized Oceanic Dealer. Use of any other Oring will void the warranty.
• Lightly lubricate the new Hatch O-ring with silicone grease and place it on the inner rim of the Battery Hatch. Ensure that it is evenly seated.
• Slide the Hatch Ring, top portion first (small opening), onto your thumb (Fig. 94).
• Carefully place the clear Battery Hatch (with O-ring) into position on the rim of the Battery Compartment, then press it evenly and completely down into place with your same thumb.
• Maintain the Battery Hatch securely in place and, using your other hand, slide the Hatch Ring down off your thumb and into position around the Battery Compartment. The tabs on the Ring fit down into the slots located at the 2 and
9 o'clock positions (Fig. 95).
• Using your fingers, turn the Ring counter clockwise 5 degrees until the tabs engage, then tighten it 5 more degrees by turning it counter clockwise with the aide of a small blade screwdriver, pressing against the upper/left arm of the Ring (Fig. 96).

Inspection
• Activate the unit and watch carefully as it performs a full diagnostic and battery check, and enters Surface Mode.
Observe the LCD display to ensure it is consistently clear and sharp in contrast throughout the screen.
WARNING: If there are any portions of the display missing or appearing dim, or if a Low Battery condition is indicated, return your Versa Pro to an
Authorized Oceanic Dealer for a complete evaluation before attempting to use it.
ALTITUDE COMPENSATION
Atmospheric pressure decreases as Altitude increases above sea level. Weather systems and ambient temperature also affect barometric pressures. Consequently, depth reading instruments that do not compensate for the decrease in ambient pressure indicate depth readings shallower than the depth they are actually at.
The Versa Pro automatically compensates for decreased ambient pressures for Altitudes between 2,000 (610 meters) and 14,000 feet (4,267 meters). Its program contains a high altitude algorithm that reduces no decompression and oxygen exposure limits to add a larger zone of caution.
The Versa Pro senses ambient pressure when it is activated, every 15 minutes while it is activated, or every 30 minutes when it is not activated. At an Altitude of 2,000 feet (610 meters), it will automatically recalibrate itself to measure depth in feet of fresh water rather than feet of sea water. It will then readjust the no decompression and oxygen limits at additional intervals of 1,000 feet (305 meters). Therefore, when returning to lower Altitudes, diving should not be conducted until the unit automatically clears of any residual nitrogen and oxygen loading and resets to operate at the new lower Altitude.
WARNING: The Versa Pro will not sense ambient pressures or provide Altitude compensation when it is wet. DO NOT dive at any different Altitude until the unit shuts off and is reactivated at the new Altitude.
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.
