never ascend shallower than your decompression ceiling. Doing so
will greatly increase your risk of decompression sickness, and place
the DataTrans Plus into a Conditional Violation Mode described later. When
coping with surge and swells, it may be difficult to stay at an exact depth.
You should stay slightly deeper (Fig. 92) than the required stop depth indi-
cated until the next shallower stop depth appears. Then, you can ascend to,
but not shallower than, that indicated ceiling stop depth.
Once you have performed the required decompression, the DataTrans Plus
will switch to the No Decompression Dive Mode, allowing additional time un-
derwater. Though more time is theoretically available, it is strongly recom-
mended that you spend the remainder of the dive continuing to decompress
at, or slightly deeper than, 10 feet (3 meters). This will let the Tissue Load-
ing Bar Graph recede further into the yellow caution (C.Z.) zone or green no
O 2
decompression (NO DECO) zone, helping you reduce your tissue nitrogen
loading as much as possible.
Warning: If you exceed certain limits, the DataTrans Plus will
not be able to tell you how to get safely back to the surface.

These situations will make the DataTrans Plus enter Violation
Modes and must be avoided at all costs. They exceed tested
limits and can result in loss of some DataTrans Plus functions
for 24 hours after the dive in which a violation occurred.
