NORM/TECH CONDITIONAL VIOLATION (CV)
Upon ascent above the required Deco Stop Depth, operation will enter CV during which no off gassing credit will be given,
meaning Deco Stop Time and TAT will not decrease.
The Audible will sound during which the alarm LED will flash. A Down Arrow will also flash (Fig. 76) until descent is made to
below the required Stop Depth, then it is removed.
• S (< 2 sec) to silence Audible.
> Other button operations and displays are similar to Deco.
If descent below the required Deco Stop Depth is made within 5 minutes, operation will resume in Deco with off gassing credit
given (Stop Time and TAT will decrease).
