__________________________________________________________________________
NOTE: Information in this manual relating to nitrox and oxygen features
only applies if you are using a dive computer specifically set for dives using
nitrox as a breathing gas.
Throughout this manual and the operating manuals, reference is made to the term
'breathing gas'. The rational being that most AERIS dive computers can be used for 'air'
dives or 'nitrox' dives. For clarity these terms are defined as -
Breathing Gas - the gaseous mixture breathed during a dive.
Air
- a breathing gas that contains approximately 21% oxygen and 79% nitrogen
(nature's common nitrogen-oxygen mixture).
Nitrox - a nitrogen-oxygen breathing gas that contains a higher fraction of oxygen than
Air (22 to 99% O2).
