VIOLATION MODES
The Violation Modes that the DataTrans Plus can enter, depending on the
situation, are termed Conditional, Delayed, and Immediate. Gauge Mode and
Permanent Violation Mode are continuations of these Violation Modes. It is
important to understand each different Violation Mode and how to carry out
emergency procedures in the event you enter one.
CONDITIONAL VIOLATION MODE
The DataTrans Plus will alert you to the possibility of losing decompression
management abilities by entering the Conditional Violation Mode. If properly
handled, the Conditional Violation Mode can assist you in getting back to the
surface and allow continued use of the DataTrans Plus. The situation that will
force the DataTrans Plus to enter a Conditional Violation Mode is: Ascent to
a Depth Shallower than the Required Decompression Ceiling (Fig. 93).
A momentary rise above the ceiling, such as with a surge or swell, could cause
this to happen. Therefore you should stay slightly deeper than the exact ceil-
ing stop depth, watching the DataTrans Plus closely when managing decom-
pression. The audible alarm will beep once per second and the Message Box
will alternately flash CEILING and VIOLATION until you descend below the
required decompression ceiling stop depth.
