in increments of '.01' BAR. When PO2 reaches 1.60 BAR, the large red bar graph

segment, the PO2 value, and PO2 symbol will flash continuously as a warning

(Fig. 70) until the level of PO2 decreases below 1.60 BAR.

In the event that you enter High PO2 Dive Mode, you must immediately focus

on reducing the partial pressure of O2 by slowly ascending to a shallower depth

at a safe rate in accordance with your nitrox training.

UNEXPECTED LOSS OF DISPLAYED INFORMATION

While No Decompression diving, if you find that any major piece of

equipment is not functioning correctly, you must abort the dive imme-

diately and surface slowly in a controlled manner. If your DataPlus stops

working for any reason, it is important that you have anticipated this possibility

and are prepared for it. This is an important reason to avoid pushing the

no decompression and oxygen tolerance limits, and a critical reason to

avoid entering decompression. Regardless of your diving habits, Oceanic

advises you to dive with additional backup instrumentation that can provide the

data necessary to properly surface if and when your primary instruments fail.

As with any other piece of equipment, unforeseen things can happen. By prepar-

ing ahead of time, you can spare yourself a great deal of frustration and disap-

pointment. If you dive in situations where your trip would be ruined or
