Operation Manual

PLAN MODE

Oceanic strongly recommends that you access the Plan Mode prior to

every dive to review the Pre Dive Planning Sequence (PDPS) that

will help you plan your dive as required to avoid exceeding no de-

compression, or oxygen exposure limits. This is especially important for

repetitive dives, when the Pre Dive Planning Sequence will indicate for you

the adjusted no decompression bottom times that are available to you for your

next dive, based on any residual nitrogen or oxygen accumulation (whichever

is in control) following your last dive and surface interval.

WARNING: The Pre Dive Planning Sequence predicts only no

decompression times for subsequent dives. Depending on cyl-

inder size, breathing gas consumption, and oxygen accumula-

tion, you may have less time available than indicated because

of breathing gas quantity or other limitations.

To access the Plan Mode, press the Advance/Left button twice beginning in the

Surface Mode. MODE:PLAN will appear, with PLAN flashing (Fig. 58). Press

the Select/Right button once to enter the Plan Mode.

If FO2 was set for 'Air', the PO2 screen will not appear and the DataTrans

Plus will begin to scroll through the Pre Dive Planning Sequence.
