Set Fo2 - Aeris Manta Operating Manual

aximum Operating Depths affected by the PO2 limit set will
not be displayed when FO2 is set for AIR.
Internally, the anta keeps track of the oxygen loading so that
if FO2 is subsequently set for a numerical value, the oxygen
accumulation for previous AIR dives will be accounted for in
the next Nitrox dive (during that dive period and series of
repetitive dives).
Once FO2 is set for a numerical value (21 to 50%) and a dive
is made, the AIR option is disabled until 24 hours elapse after
the last dive. The AIR option will not be displayed in Set FO2
selections until a full 24 hour Surface Interval has elapsed.
If FO2 is set for 21%, it will remain set for 21% for that series
of dives until set for a higher numerical value.
