Oxygen Limit Warning; Out-Of-Range Warning - Apeks Quantum Owner's Manual

Oxygen Limit Warning

When the next to last segment appears, the Quantum
sounds an audible alarm for 3 seconds and flashes the bar
graph for 10 seconds. When the last segment appears, the
audible alarm will sound for three seconds, but the entire
bar graph will flash until you ascend to a shallower depth
and the bar graph reduces to seven segments.

Out-of-Range Warning

The out-of-range warning only occurs when you take the
Quantum to extreme depths and/or time limits. To acti-
vate the out-of-range warning, you must exceed one of the following limits:
1. Maximum depth limit of 100m/328 ft.
2. Dive time limit of 599 minutes.
3. Deepest decompression stop of 27m/90 ft.
4. Decompression stop time of 99 minutes.
5. Total ascent time of 999 minutes.
In the extremely unlikely event that you exceed one of the limits listed above, the com-
puter will sound an alarm, replace the depth display with dashes, and flash the entire
display. The computer cannot be used for 48 hours after an out-of-range warning.
