SET GAS
Within this submenu you can change the three available gas mixes from air to any nitrox mix between 21 - 100
FO
2
(% O
2
). Nitrox mixes are displayed with their corresponding MOD (Maximum Operating Depth) and the cur-
rent PO
2
Alarm setting for the selected gas. Default settings are FO
2
AIR with no PO
2
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 PO
2
alarm value will default to 1.40 until changed. Additionally, the i450T allows
for each gas (1 - 3) to have individual PO
2
alarm settings.
NOTE: Once any Gas is set for Nitrox, any other Gas set for AIR will automatically be set to 21%. The
AIR option will not be displayed as an FO
2
setting until 24 hours elapse after the last dive.
NOTE: When FO
2
is set for AIR, oxygen related data (such as PO
2
, % O
2
) 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.
