CONDITIONAL VIOLATION (CV)
Upon ascent above the required Deco Stop Depth, operation will enter CV during which no off gassing credit will be given; with
remaining Deco Stop Time and TAT freezing.
The Audible will sound and the LED will flash. The full TLBG and Down Arrow icon will flash (Fig. 82) until the Audible is si-
lenced, then the TLBG will be solid.
• S (< 2 sec) - to silence Audible.
> The graphic ABOVE STOP will be displayed and the Down Arrow icon will flash until descent is made to below the
required Stop Depth (within Stop Zone), then full the Stop icon (Stop Bar with both Arrows) will be on solid.
• L (press) - to activate the Backlight.
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 decrease).
DELAYED VIOLATION 1 (DV1)
Once above the Deco Stop Depth for more than 5 minutes, operation will enter DV1 which is a continuation of CV**.
Again, the Audible will sound and the LED will flash. And, the full TLBG will flash (Fig. 83) until the Audible is silenced.
> Down Arrow icon continues to flash until descent to below required Stop Depth (within Stop Zone), then full Stop icon
(Stop Bar with both Arrows) will be on solid.
• L (press) - to activate the Backlight
When descent below the required Deco Stop Depth is made, operation will resume in Deco with off gassing credit given (Stop
Time and TAT decrease).
**The difference between CV and DV1 is that DV1 causes operation to enter Violation Gauge Mode 5 minutes after surfacing
from that dive.
