Central Nervous System (CNS) oxygen toxicity danger
If your COSMIQ
+
calculates a CNS oxygen toxicity level of 80%, the letters CNS will

shallower depth. The alarm will increase in frequency if you fail to do so and as the
toxicity level reaches 85%. In case of a CNS alarm, conduct a safety stop and end the
dive immediately.
Maximum Operating Depth (MOD) exceeded
If you have exceeded your MOD during a dive, your COSMIQ
+
will sound an alarm and
the letters PO2willashonscreenalongwithanarrowindicatorinstructingyouto
ascend to a shallower depth. The alarm will continue to sound until you ascend above
the MOD. In case of an MOD alarm, ascend to a shallower depth and consider ending
the dive.
Safe ascent rate exceeded
Your COSMIQ
+
considers an ascent rate slower than 12 m (40 ft) per minute to be
safe. If you exceed this rate, the alarm will sound until you slow your ascent. The
ascent rate bar operates according to the table below.
Bar Indicator Ascent Rate
No bars Slower than 4 m (13 ft) per minute
1 bar 4–6 m (13–20 ft) per minute
2 bars 6–8 m (20–26 ft) per minute
3 bars 8–10 m (26–33 ft) per minute
4 bars 10–12 m (33–40 ft) per minute
5 bars Faster than 12 m (40 ft) per minute
5.3 Diving in Bottom Timer Mode
No decompression calculations are done in Bottom Timer Mode; only depth, time
and temperature are measured. Use this mode when you use your COSMIQ
+
as a
secondary dive computer or as a depth gauge and timer only.
5.3.1 Entering the water
Just like diving in Scuba Mode, there are two ways to start a dive in Bottom Timer
