Air Consumption and Depth are continuously monitored and Air
Time Remaining reflects any change in circumstances. For
example, when a buddy starts breathing from your Octopus or
you suddenly find yourself swimming against a strong current
and begin breathing more rapidly, the ATOM will recognize the
change and adjust the Air Time Remaining accordingly.
Air Time Remaining is the time you can remain at the present
Depth and still safely surface with the Tank Pressure Reserve that
you selected during setup (End Pressure Alarm Setting).
Air Time Remaining (Fig. 82a), identified by the symbols AIR
and TIME, can be viewed when the Alternate #1 Display is
accessed during dive modes. In the event that ATR becomes less
than No Deco and O2 Time, it will be displayed on the Main
Display as Dive Time Remaining until it becomes greater than
one or the other.
Air Time Remaining (ATR) Alarm
When Air Time Remaining (ATR) decreases to 5 minutes (0:05),
the Audible Alarm will sound and the LED will flash. If it de-
creases to 0:00, the Audible will sound again and the LED will
flash. The message LOW > AIR > TIME will scroll at the top of
the screen (Fig. 83) until Air Time Remaining becomes greater
than 5 minutes (0:05).
