PRE DIVE PLANNING SEQUENCE ™ (PDPS)
Prior to every dive, Oceanic strongly recommends that you view the
PDPS to review the no decompression limits that will help you plan
your dive as required to avoid decompression or oxygen toxicity. This
is especially important for repetitive dives, when the PDPS (Fig. 35) will indicate
for you the adjusted no decompression bottom times that are available to you on
your next dive, based on any residual nitrogen or oxygen accumulation (which-
ever is in control) following your last dive and surface interval.
WARNING: The PDPS predicts only no decompression times for
subsequent dives. Depending on cylinder size, breathing gas
consumption, and oxygen accumulation, you may have less time
available than shown in the PDPS because of breathing gas
quantity or other limitations.
As you will recall from page 5, after activation and diagnostics, the unit will
enter the Surface Mode for several seconds, then display FO2, then the maxi-
mum depth that can be achieved with a PO2 of 1.60 BAR, then automatically
commence the PDPS, identified by the PDPS icon (Fig. 35a). At that time and
once each minute afterward, the PDPS will sequentially show depths from 30
feet (9 m) to 160 feet (48 m) in 10 foot (3 m) increments, which takes about 42
seconds.
