DEFAULT NITROX SETTINGS
In the NITROX Mode, when set to standard air (21% O
2
), the instrument can be used
as an air dive computer. It remains in this air mode until the O
2
% setting is adjusted
to any other percentage of oxygen (22% - 50%).

Manually entered values for oxygen percentage are retained for about two hours after
the setting if a dive series has not started. In case a dive series is started, the set
value is retained until a new dive series is started or a new value is entered manually.
