SET GAS (MIX)
Within this submenu you can change the three available gas mixes from air to any nitrox mix between 21 - 100 FO2 (% O2), PO2 Alarm settings,
and whether to use 1, 2, or 3 gases. Nitrox mixes are displayed with their corresponding MOD (Maximum Operating Depth) and the current PO2
Alarm setting for the selected gas. Default settings are FO2 Air with no PO2 alarm value for Gas 1, and OFF for Gas 2 and 3. Settings revert to
the defaults when 24 hours elapse without conducting a dive. If you set a nitrox mix value for any gas the PO2 alarm value will default to 1.60 until
changed.
NOTE: Once any gas is set for nitrox, any other gas that is set for AIR will automatically be set to 21%. The AIR option
will not be displayed as an FO2 setting until 24 hours elapse after the last dive.
NOTE: When FO2 is set for AIR, oxygen related data (such as PO2, % O2) will not be displayed at any time during the
dive, on the surface, or in Plan Mode. Though these oxygen values will be tracked internally for use in any subsequent
nitrox dives.
NOTE: Gas 1 cannot be set to OFF.
