WARNING: Prior to diving with the Pro Plus 2, 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.
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.
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.
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.
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.
ALPHA / NUMERIC DISPLAYS Cylinder Pressure Display 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). b N2 FEET 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).
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/middle portion of the display (Fig. 7a) and a second time display (Fig. 7b) is located in the center/right.
NOTE: 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. The Informational Displays are described in detail as the various operating modes they appear in are presented throughout this manual.
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).
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. a N2 O2 ATR Fig. 8 - Battery Indicator 16 NOTE: Extensive use of the Backlight reduces estimated Battery life.
Low Battery Condition • 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 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.
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.
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 prior to each nitrox dive. Setting FO2 for a nitrox dive is described on page 25. O ATR Fig.
WARNING: Prior to diving with the Pro Plus 2, 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.
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.
SURFACE MODE Surface Mode (Fig. 15), 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). NOTE: If the wet contacts are bridged, the graphic 'H2O' will appear in place of the dive number '0' (Fig. 16). After the unit is rinsed and dried, '0' will replace 'H2O'. N2 O2 PSI ATR Fig.

DECOMPRESSION DIVE MODE The Pro Plus 2 is designed to help you by providing a representation of how close you are to entering Decompression. Decompression Dive Mode (Fig. 55) activates when theoretical No Decompression time/depth limits are exceeded. Upon entering Decompression Mode, the Audible Alarm will sound and the red LED Warning Light will flash for 10 seconds (unless set OFF), or until acknowledged.
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. 56a) and decompress for the Stop Time indicated (Fig. 56b). 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.
N2 DECO FEET MAX Decompression Dive Mode - Display #2 (Fig. 57) Information includes - Current Depth, Maximum Depth for that dive (and icon), Elapsed Dive Time (and icon), Total Ascent Time (and Mode icon), both Arrows and the Deco Bar, and the applicable bar graphs. • Press and release the Left (Advance) button again to view Display #3.

VIOLATION MODES While in Violation Modes the Alternate Displays previously described can be accessed using the Left (Advance) button, and the Backlight can be activated using the Right (Select) button. • The Pro Plus 2 will automatically revert to the Main Display after 3 seconds unless the Left (Advance) button is pressed to view another display of information. Conditional Violation Mode (Fig. 60) If you ascend shallower (Fig. 60a) than a Required Decompression Ceiling Stop Depth displayed (Fig.
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. The Tissue Loading Bar Graph will recede into the yellow Caution Zone and the Pro Plus 2 will revert to the No Decompression Dive Mode.
Delayed Violation Mode #2 (Fig. 62) N2 DECO FEET The Pro Plus 2 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 the 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.
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 Pro Plus 2 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. 65). 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'.

DI RESP O VER Be a RESPONSIBLE DIVER at all times.
WARNING: Prior to diving with the Pro Plus 2, 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.
CARE AND CLEANING Protect your Pro Plus 2 from shock, excessive temperatures, 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 Pro Plus 2 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. 95a), Download Interface Port (Fig. 95b), and Buttons are free of debris or obstructions.
O DI RESP To return your Pro Plus 2 to Oceanic: • Record all dive data in the Log and/or download the data in memory. All data will be erased when it receives factory service. • Package it using a protective cushioning material. • Include a legible note stating specific reason for return, your name, address, daytime phone number, serial number, and a copy of your original sales receipt and Warranty Registration Card.
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.
Battery Removal Examine the Case Back to locate the Battery Hatch (Fig. 96a): • Remove the 4 screws that secure the Battery Hatch to the Housing by turning counter clockwise. • Lift the Hatch up and away from the Housing. • Lift the Battery, positive (+) end first, out of the Battery Compartment. • Remove the Battery Hatch O-ring and inspect it for any signs of deterioration or deformity. DO NOT use tools to remove the O-ring. • O-ring replacement is highly recommended to ensure proper sealing.
Moisture in the Battery Compartment • If moisture is found, it is best to have the unit inspected and cleaned by an Authorized Oceanic Dealer. • 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'). • Closely check all of the sealing surfaces for any signs of damage that might impair proper sealing.
Battery Hatch Installation • Ensure that the Battery is properly oriented and the Hatch O-ring is evenly seated. • Carefully place the Battery Hatch into position so that it seats on top of the O-ring, and while holding it in place, secure it with the 4 screws by turning them clockwise. DO NOT attempt to use any other screws. • Carefully tighten the screws by alternately turning them each one turn at a time (Fig. 99).
