DECOMPRESSION MODE
Decompression mode activates when theoretical No Decompression time and depth limits are exceeded.
Upon Entry into Deco, the Audible will sound and the LED will flash. The full TLBG and graphic UP with Up Arrow icons will flash
(Fig. 80) until the Audible is silenced by pressing S or 10 seconds elapse.
• S (< 2 sec) - to silence the Audible.
> The TLBG stops flashing when the Audible is silenced.
> The graphic UP with Up Arrow icons continue to flash until within 10 FT (3 M) of and below the required Stop Depth (within
the stop zone), then they are removed.
Managing Deco Stops
To fulfill your decompression obligation, you should make a safe controlled ascent to a depth slightly deeper than, or equal to, the
required Stop Depth indicated and decompress for the Stop Time indicated.
The amount of decompression credit time that you receive is dependent on Depth, with slightly less credit given the deeper you
are below the Stop Depth indicated.
You should stay slightly deeper than the required Stop Depth indicated until the next shallower Stop Depth appears. Then, you
can slowly ascend to, but not shallower than that indicated Stop Depth.
