AUDIBLE ALARM
Most warning situations that activate the Audible Alarm while operating in NORM or
GAUG Mode cause the ATOM to emit 1 beep per second for 10 seconds, or until the
situation is corrected, or it is acknowledged by momentarily pressing and releasing the S
button (less than 2 seconds). After being acknowledged and the situation corrected, the
Alarm will sound again upon reentry into the warning situation, or entry into another type
of warning situation.
FREE Dive Mode has its own set of Alarms which emit 3 short beeps either 1 or 3 times
which cannot be acknowledged or set Off.
A red LED Warning Light, located on the left side of the housing, is synchronized with the
Audible Alarm. It will flash as the Audible Alarm sounds. It will turn Off when the Alarm is
acknowledged or the situation is corrected. The Audible and LED will not be active if the
Alarm is Set OFF (a group A setting).
Situations that will activate the NORM/GAUG 10 second Alarm include -
Air Time Remaining (ATR) at 5 minutes, then again at 0 minutes.
ATR becomes less than No Deco and O2 Time Remaining for 1 minute.
Turn Pressure at the Set Point selected (Transmitter 1).
End Pressure at the Set Point selected (active Transmitter).

Dive Time Remaining at the Set Point selected.
