Upon entering Decompression Mode, you should begin a safe
controlled ascent to a depth slightly deeper than, or equal to, the
Required Ceiling Stop Depth indicated (Fig. 25a) and decom-
press for the Stop Time indicated (Fig. 25b).
• The UP Arrow and Deco Bar will flash if you are more than
10 feet (3 meters) deeper than the Required Ceiling Depth.

Ceiling Depth, both Arrows and the Bar appear solid.

The amount of decompression
Credit time
that you receive is
dependent on Depth, with slightly less Credit given the deeper
you are. 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 ceiling Stop Depth.
Main Display information includes - Current Depth, Required
Ceiling Stop Depth/Time, Total Ascent Time (and Mode icon),
