Section 2: Diving with the Monitor 3 Air
31
Summary of Attention Messages and
Alarms
The Monitor 3 Air draws your attention to certain situa-
tions and warns you of unsafe diving practices. Attention
messages and alarms are always visual and acoustical
while underwater; they are only optical at the surface
except for the decompression alarm.
Attention Messages
Attention messages are given by symbols, letters, or
flashing figures. In addition, two short beeps can be heard,
in intervals of 4 seconds, in two different frequencies.
Attention messages appear in the following situations:
Altitude dive
During a change to a higher
altitude, the Monitor 3 Air
displays an altitude sector icon
and the corresponding adapta-
tion time.
End of no-stop time
To avoid making a decompression dive,
a "0" flashes during the last minute of
no-stop time to alert you to ascend to
a shallower depth. Also, two beeps are
sounded.
Air Time Remaining is less than 3
minutes
To avoid a potential out-of air
situation, immediately begin your
ascent.
