DIVE OPERATION
© Aqua Lung International, Inc. (2015)
CONDITIONAL VIOLATION (CV)
Upon ascent above the required Decompression (deco) Stop depth, operation will enter Conditional Violation dur-
ing which time no off gassing credit will be given.
The Audible alarm will sound and the alarm LED will flash. The full N2 Bar Graph, down arrows, and DOWN mes -
sage will flash until the audible alarm is silenced, then the N2 Bar Graph will be solid.
• The down arrows continues to flash until descending below the required Stop Depth (within stop zone), then the
full stop graphic (opposed arrows with stop bar) will be on solid.
• If you descend deeper than the required Decompression Stop before 5 minutes elapse, Decompression opera-
tion will continue with no off gassing credit given for time above the Stop. Instead, for each minute above the
Stop 1½ minutes of penalty time will be added to the required Stop Time.
• The added penalty (decompression) time will have to be worked off before obtaining off gassing credit.
• Once the penalty time is worked off, and off gassing credit begins, required Decompression Stop Depths and
Time will decrease toward zero. The N2 Bar Graph will recede into the No Decompression zone, and operation
will revert to No Decompression mode.

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 full N2 Bar
Graph will flash until it is silenced. ALT screens are accessed and appear similar to Deco ALT screens.
*The difference is that 5 minutes after surfacing from the dive, operation will now enter Violation Gauge Mode.
• Down arrow and DOWN message continues 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 i450T will enter DV1 Surface mode for 5 minutes upon surfacing from the dive.
Down arrows and Deco Stop depth/time will alternate with SURF TIME. After 5 minutes on the surface in DV1
mode, the unit will enter VGM (Violation Gauge Mode).
