In the case of an MOD alarm, you must obey the alarm warnings and ascend to a shallower depth.
Consider ending the dive.
WARNING: DO NOT EXCEED THE MAXIMUM OPERATING DEPTH (MOD). Exceeding the MOD
greatly increases the risk of oxygen toxicity, which may cause convulsions and drowning.
WARNING: ONLY DIVERS WHO HAVE RECEIVED SPECIALIZED TRAINING FROM A RECOGNIZED
AGENCY SHOULD DIVE WITH NITROX. Diving with Nitrox poses risks that are different from those
associated with using Standard Air, and therefore require specialized training in order to understand and
avoid. Nitrox diving without proper training may result in errors that can lead to death or serious injury.
5.2.8 Ascent Rate
COSMIQ
+
monitors your ascent rate at all times throughout a dive. Your ascent rate is represented
by a graphic bar on the left-hand side of COSMIQ
+
’s display screen. COSMIQ
+
’s algorithm considers
an ascent rate slower than 12 meters/40 feet per minute to be a safe ascent rate. If the safe ascent
rate is exceeded, the alarm will sound and will continue to beep until you slow your ascent rate. The
ascent rate bar operates according to the table below:
Ascent Rate Ascent Speed
No bars Slower than 4 meters/13 feet per minute
1 bar 4–6 meters per minute
13–20 feet per minute
2 bars 6–8 meters per minute
20–26 feet per minute
3 bars 8–10 meters per minute
26–33 feet per minute
4 bars 10–12 meters per minute
33–40 feet per minute
5 bars Faster than 12 meters per minute
Faster than 40 feet per minute
WARNING: NEVER ASCEND FASTER THAN THE SAFE ASCENT RATE OF 12 METERS/40
FEET PER MINUTE. Faster ascents may increase the chance of decompression illness.
