PATENTNOTICE
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), Air Time Remaining (U.S. Patent no. 4,586,136), 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).
DECOMPRESSIONMODEL
The programs within the Pro Plus 2 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 Pro Plus 2 dive computer model is based upon the latest research and experiments in decompression theory. Still, using the Pro Plus 2, 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 Pro Plus 2 !
It is extremely important that you read this Operating Manual in sequence and understand it completely before attempting to use the Pro Plus 2.
It is equally important that you read the Oceanic Dive Computer Safety and Reference Manual (Doc. No. 12-2262) provided with your Pro Plus 2. It contains information that you must become familiar with prior to diving with your Pro Plus 2.
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.

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 valueotherthan'Air'(e.g.,anumericalvalue).

OxygenAccumulationBarGraph(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.
VariableAscentRateIndicator(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 VARI represent two sets of speeds which change at a reference depth of 60 feet (18 meters). Refer to the chart (Fig. 4) for segment values.

Air Time Remaining Bar Graph (ATRBG)
The Air Time Remaining Bar Graph (Fig. 5a) provides a graphic representation of the time that you can remain at your present depth and then, following a safe ascent, surface with a predetermined reserve of breathing gas.
This calculation and display is based on your Breathing Gas Consumption Rate that is continuously monitored by the Pro Plus 2, and it takes into account the breathing gas required for a safe ascent including any required decompression stops.

DIVETIMEREMAINING
The Pro Plus 2 constantly monitors three critical pieces of information; no decompression status, oxygen accumulation, and breathing gas consumption rate. Refer to the Oceanic Dive Computer Safety and Reference Manual which describes Dive Time Remaining which is a display that indicates the time that is more critical for you at that particular moment (i.e.; whichever time is the least amount available of the three).
Displayed will be either Time Remaining before reaching the No Decompression limit (Fig. 5b), or Time Remaining before reaching the limit for Oxygen Accumulation, or Time Remaining before reaching the End Pressure Alarm set point.

ALPHA / NUMERIC DISPLAYS
CylinderPressureDisplay
Cylinder Pressure (Fig 6a) is displayed any time the Pro Plus 2 is connected to a pressurized cylinder and in an active operating mode.
Values of pressure are displayed numerically from 10 PSI (.5 BAR) up to 5000 PSI (352 BAR) in increments of 10 PSI (.5 BAR).
DepthDisplays
During a dive, the Current Depth display (Fig. 6b), indicates depths from 0 to 330 feet (99.9 meters) in 1 foot (.1 meter) increments.
By pressing the Left (Advance) button, the Maximum Depth reached during that dive will be displayed in the center/left portion of the display (Fig. 6c).
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 Left (Advance) button.
12
TimeandDate 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/middle portion of the display (Fig. 7a) and a second time display (Fig. 7b) is located in the center/right. Both displays are identified by clock icons.
• 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 only to identify dive data while it is viewed in the Log Mode (see page 70). 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.
TemperatureDisplay
Ambient Temperature is displayed in the center/left portion of the screen (Fig. 7c) while in the Surface Mode and Log Mode, and can be viewed as part of an Alternate Display when the Left (Advance) 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'.

AUDIBLEALARM
LEDWarningLight
A red LED Warning Light will light and a Speaker icon will appear when the Audible Alarm emits a tone. They will turn off when the Alarm is acknowledged, and will not activate if the Audible is Set OFF (a user setting).
When warning situations activate the Alarm, the unit will emit a continuous tone for 10 seconds, or until the situation is corrected, or it is acknowledged by the user pressing the Left (Advance) 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.
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
Situations that will sound the Alarm, if it is turned ON (a user setting), include -
•Entry into Decompression Mode.
•Air Time Remaining Bar Graph Alarm (a user setting).
•Air Time Remaining = 5 minutes.
•Air Time Remaining = 0 minutes.
•Turn Pressure Alarm (a user setting).
•End Pressure Alarm (a user setting).
•PO2 => than the Max PO2 Alarm (a user setting), or => 1.60 ATA.
•Descent deeper than the Max Depth Alarm (a user setting).
•Tissue Loading 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 ceiling stop depth for less than 5 minutes (referred to as a Conditional Violation).
•Ascent rate exceeds 60 feet/minute (18 meters per 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 10 second continuoustone willbefollowedby a5 second steady beep that will not turn off when acknowledged, even if it was user Set OFF -
•Ascending above a required Decompression ceiling stop depth for more than 5 minutes (referred to as a 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).

Fig.8-Battery Indicator
SMARTGLO® BACKLIGHT
To activate the Backlight - press the Right (Select) button.
•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 button depression time plus the user set additional Duration time (3 or 7 seconds).
•Press the button again to activate as desired.
NOTE: Extensive use of the Backlight reduces estimatedBatterylife. Also,theBacklightdoesnot operate during a Low Battery Condition or when downloading data to a PC.
POWER SUPPLY
The Pro Plus 2 utilizes one (1) 3 volt, CR2 Lithium Battery that should provide from 50 dive hours of operation, if you conduct 1 - one hour dive each time the unit is activated, to over 150 dive hours of operation, if you conduct 3 or more one dives each time the unit is activated.
Battery Indicator
A Battery Indicator (Fig. 8a) provides an indication of Battery condition. The Battery Indicator will be displayed during Surface Mode. It will not be displayed during Dive Mode(s).
16
LowBatteryCondition
•Voltage level is checked upon activation and every 10 minutes during operation.
•When 75 % of the Rated Power has been consumed, only the lower bar of the Indicator will be displayed and the full icon will flash (Fig. 9) 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 Battery Indicator will flash 5 times followed by shutdown of the unit.
•If a Low Battery Condition exists when the unit is manually activated (by pressing the button), the graphic bAT and the Battery Indicator will appear flashing for 5 seconds followed by shutdown of the unit.
•If the button is not pressed to activate the unit prior to a dive (e.g., the unit activated automatically by immersion in water), 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 and the unit will not enter Dive Mode.

•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 upon entry into Surface Mode.
•When the Battery is removed, settings and 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 must be reset.
FO2MODE
After Activation, the Pro Plus 2 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 Pro Plus 2 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).
18
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.
FO250%Default
If the Default function 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 function 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.
WARNING: When the unit shuts off, the FO2 set point will default to AIR regardless if the 50% Default is set ON or OFF. Always set, or verify, the FO2 set point priortoeachnitroxdive.
Setting FO2 for a nitrox dive is described on page 25.

ACTIVATION and SETUP
21
ACTIVATION
To Activate the Pro Plus 2, press and release the Left (Advance) 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.
Backup Activation (only if Water Activation is set ON)
As a backup, the Pro Plus 2 will also automatically activate by water contact. This is accomplished by bridging the gap between contacts located on the Button stems and case. The graphic H2O that will be displayed as an indication is described later.
