Delayed Violation 2 (Dv 2); Delayed Violation 3 (Dv 3); Violation Gauge Mode During A Dive - Aqua Lung i750TC Owner's Manual

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.
• Up arrows flash if 3 m (10 ft) deeper than the required Stop Depth.
• Once within 3m (10 ft) of and below the required Stop Depth, the DECO STOP message and full stop graphic
(opposing arrows with stop bar) will be displayed solid.

DELAYED VIOLATION 3 (DV 3)

If you descend deeper than the maximum functional depth*, the audible alarm will sound. Also, the up arrows,
and GO UP TOO DEEP message will flash. Only dashes will display for Current Depth signifying that you are too
deep.
* The maximum functional depth (Dive/Gauge/Free = 100 m / 330 ft) is the depth at which the i750TC can properly perform calculations or
provide accurate display information.
Upon ascending above the maximum functional depth, current depth will be restored. However, the log for that
dive will display dashes for max depth.
VIOLATION GAUGE MODE (VGM) DURING A DIVE
During Dive mode dives, operation will enter VGM when Decompression requires a Stop Depth greater than 21
m (70 ft). It will also enter VGM if Deco is activated during a dive in Free mode, described later. Operation would
then continue in VGM during the remainder of that dive and for 24 hours after surfacing. VGM turns the i750TC
into a digital instrument without any decompression or oxygen related calculations or displays. Upon activation of
VGM, the audible alarm will sound. The message GO UP VIOLATION with up arrows will flash. After the audible
alarm becomes silent (10 seconds), the NO DECO (No Decompression) and N2 Bar Graph will not display for the
rest of the dive. GTR (Gas Time Remaining) will be moved to an ALT screen.
