SETTING FO2 FOR NITROX DIVES

For each value of FO2, the MOD (Max Operating Depth) that can be achieved for the

PO2 Alarm limit previously set will be displayed.

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

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

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

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

FO2 for Gas 1 continues to reset to the FO2 50% Default after subsequent repetitive dives

until 24 hours elapse after the last dive, or the FO2 50% Default is turned Off.

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

for the remainder of that series of repetitive dives.

The default FO2 for Gas 1 each new dive period is AIR.

When FO2 for Gas 1 is set for AIR, the calculations are the same as when it is set to an

FO2 of 21%. When FO2 for Gas 1 is set to AIR, it remains set for AIR until it is set for a

numerical FO2 value (21 to 50%).

When FO2 is set only to AIR, the O2BG and PO2 values and/or warnings will not be

displayed during the dive.

MODs affected by the PO2 limit set will not be displayed when FO2 for Gas 1 is set to

AIR.
