SET F (GAS MIX)
Within this submenu you can change the two 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.
Pressing the SEL button while viewing the Set Gas Lead-in screen accesses the Set Air/EAN (Enriched Air Nitrox) screen. Within this screen you can
select whether to use Air or Nitrox gas mixes. If Air is selected, the Veo 4.0 will return you to the Set Gas Lead-in screen in the menu. If EAN is
selected, the Veo 4.0 will allow you to choose a gas FO2 (%O2) between 21-100%, PO2 Alarm settings, and whether to use 1, 2, or 3 gases. Ad
-
ditionally, the Veo 4.0 allows for each gas to have individual PO2 alarm settings. Within the Set Gas PO2 Alarm 1, 2, and 3 screens the the current
PO2 Alarm setting and corresponding MOD (Maximum Operating Depth) are displayed.
NOTE: Once a gas is set for nitrox, the other gases that are 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.
