SET F MENU (NORM FO2) 

Sequence >> FO2 Gas 1 >> FO2 Gas 2 >> 50% Default

When the FO2 50% Default is set Off, FO2 will remain set at the last FO2 Gas 1 Set Point 

saved during that period of activation.

When the FO2 50% Default is set On and FO2 for Gas 1 is set for a numerical value, 10 

minutes on the surface after that dive the FO2 Gas 1 will be displayed as 50 and further 

dives will be calculated based on 50% O2 for oxygen calculations and 21% O2 for Nitro-

gen calculations (79% Nitrogen), unless FO2 Gas 1 is set before the dive.
