Datamax Pro Plus
Once a dive is made with the Pro Plus set as a nitrox computer (FO2 set for a
numerical value), it cannot be set for 'Air' until 24 hours after the last nitrox
dive. However, you can set FO2 for 21% for use with air.
PRE DIVE PLANNING SEQUENCE™
Oceanic strongly recommends that you review the Pre Dive Planning
Sequence (PDPS) prior to every dive to help you plan your dive as re-
quired to avoid exceeding no decompression or oxygen exposure lim-
its. This is especially important for repetitive dives, when the Pre Dive Plan-
ning Sequence (Fig. 34) will indicate for you the no decompression dive times
that are available to you on your next dive, based on any residual nitrogen or
oxygen accumulation (whichever is in control) following your last dive and sur-
face interval.
To access the Pre Dive Planning Sequence while in the Surface Mode:
• press the Advance (Left) button 3 times
• press repeatedly, or press and hold, the Select (Right) button
• a sequence of depths from 30 to 160 feet (9 to 48 meters) in 10 foot (3
meter) increments will be displayed
The unit reverts to Surface Mode 10 seconds after the Select (Right) button is
released, unless the Advance (Left) button is pressed to access the Log Mode.
