Operation Manual

Managing Decompression Stops

You should stay slightly deeper than the required Deco Stop Depth indicated until the next

shallower Stop Depth appears. Then, you can slowly ascend to, but not shallower than,

that indicated Stop Depth. The amount of decompression credit time that you receive

while at a decompression stop is dependent on depth, with slightly less credit given the

deeper you are below the stop depth indicated.

Once all required decompression has been completed, the PDC will switch to the No

Decompression Dive Mode, as indicated by Total Ascent Time = 0:00 (min), and the TLBG

receding into the No Decompression zone.

DTR then appears, displaying NDC, or OTR, or ATR, whichever applies depending on the

conﬁguration of your PDC.

VIOLATION MODES

When you exceed certain limits, Oceanic PDCs alert you with visual and/or audible warn-

ings and operate in special Violation modes.

WARNING: Displays and alarms associated with Violation Modes are

provided in the Operating Manual for your specic PDC. Read and

understand the Operating Manual prior to diving with your PDC.

Conditional Violation Mode (CV)

CV is entered during Deco if you ascend shallower than the Required Deco Stop Depth

displayed. If you descend below the Required Stop Depth before 5 minutes have elapsed,

the unit will continue to function in Decompression Mode.
