  • Page 8 It is extremely important that you read this Operating Manual in sequence and under- stand 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.
  • Page 9 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.
  • Page 10 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 addi- tional exposure is allowed for that dive and 24 hour period.
  • Page 11 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.;...
  • Page 12 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).
  • Page 13 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).
  • Page 14 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.

  • Page 48 FEET 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 seg- ments displayed will begin to recede, offering a graphic representation of your multilevel diving capability.
  • Page 49 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. The Variable Ascent Rate Indicator (VARI) shows how fast you are ascending.
  • Page 50 FEET 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 the display at any given time during the dive.
  • Page 51 During conditions in which Cautionary type information is displayed (e.g., No Decom- pression Safety Stop, Decompression, High PO2, etc.), there is a Main Display of impor- tant 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 Right (Select) button.
  • Page 52 FEET Information includes Current Depth, Max Depth for that dive and icon, Elapsed Dive Time and icon, Dive Time Remaining and icon, Tank Pressure, and the applicable bar graphs.

  • Page 54 The Pro Plus 2 is designed to help you by providing a repre- sentation of how close you are to entering Decompression. Decompression Dive Mode (Fig. 55) activates when theoreti- cal 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.
  • Page 55 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.
  • Page 56 DECO FEET 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.

  • Page 57 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.
  • Page 58 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.
  • Page 59 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.
  • Page 60 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. During a Dive, if a ceiling much greater than 60 feet (18 meters) is required, an Immediate Violation Mode will be entered.
  • Page 61 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.
  • Page 62 FEET 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.
  • Page 63 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.
  • Page 64 FEET When Digital Gauge Mode is set for ON, the Pro Plus 2 will operate as a Digital Depth Gauge/Timer without performing nitrogen and oxygen calculations (Fig. 69). Time of Day and Elapsed Dive Time will also be displayed. If your Pro Plus 2 stops working for any reason, it is impor- tant that you have anticipated this possibility and are pre- FEET pared for it.
  • Page 66 When you ascend to 3 feet (1 meter) or shallower, the Pro Plus 2 will enter Surface Mode and begin counting your surface interval. The first 10 minutes is, in affect, a Transition Period during which time the following information is displayed (Fig. 71): •...
