AUDIBLE ALARM
When warning situations activate the Alarm, the unit will emit a continuous tone for 30
seconds, or until the situation is corrected, or it is acknowledged by pressing the
Advance (Front) button for 2 seconds. If acknowledged by the user and the situation
corrected, the Alarm will sound again upon reentry into the warning situation, or entry
into another type of warning situation.
Warning situations that will sound the Alarm, if it is turned ON, include -
• Entry into Decompression Mode
• PO2 => than the Max PO2 Alarm (a user setting), or => 1.60 ATA.
• Descent deeper than the Max Depth Alarm (a user setting).
• Nitrogen Bar Graph Alarm (a user setting).
• Dive Time Remaining Alarm (a user setting).
• Elapsed Dive Time Alarm (a user setting).
• O2 Accumulation => allowable per dive limit, or limit for a 24 hour period.
• Ascending above a required Decompression stop depth for < 5min. (Cond.Violation).
• Asc. rate exceeds 60fpm (18mpm) if > 60ft (18m), or 30fpm (9mpm) if <= 60ft (18m).
During the following situations, the 30 second continuous tone will be fol-
lowed by a 5 second steady beep that will not turn off when acknowledged,
even if it was user Set OFF -
• Ascending above a required Decompression stop depth for more > 5 min. (Delayed
Violation).
• Decompression requires a ceiling stop depth => 70 FT (18 M).
• Being on the surface for 5 minutes after a Conditional Violation (Perm.Violation).
