Delayed Violation 1 (Dv 1); Delayed Violation 2 (Dv 2) - Aqua Lung i770R Owner's Manual

DELAYED VIOLATION 1 (DV 1)

If you remain shallower than a Deco Stop Depth for more than 5 minutes, operation will enter DV1* which is a
continuation of CV with penalty time still being added. Again, the audible alarm will sound and the DOWN TO
STOP message will flash until the audible alarm is silenced
*The difference from Conditional Violation is that the i770R will now enter Violation Gauge Mode 5 minutes after surfacing regardless of clear-
ing the decompression stops before surfacing.
• Down arrows and DOWN TO STOP message continue to flash until descending below the required Stop Depth,
then the full stop graphic will be on solid.
• If the DV1 status is ignored, the i770R will enter DV1 Surface Mode for 5 minutes upon surfacing from the dive.
Down arrows and Deco Stop depth/time will flash. After 5 minutes on the surface in DV1 Mode, the unit will enter
VGM (Violation Gauge Mode).

DELAYED VIOLATION 2 (DV 2)

If the calculated Decompression obligation requires a Stop Depth between 18 m (60 ft) and 21 m (70 ft), opera-
tion will enter DV2. The audible alarm will sound. Additionally, the full N2 Bar Graph will flash until the audible is
silenced. The i770R will advance to Violation Gauge Mode (see below section) if the required decompression stop
depth exceeds 21 m (70 ft).
