5.8.4. Setting the nitrox values
If set to the NITROX mode, the correct oxygen percentage of the gas in your cylinder
must always be entered into the computer to ensure correct nitrogen and oxygen
calculations. In addition, the oxygen partial pressure limit must be set. When in the
NITROX setting mode, the equivalent allowed maximum depth, based on the chosen
setting, will also be displayed.
The default oxygen percentage (O
2
%) setting is 21% (air) and oxygen partial pressure
(PO
2
) setting 1.4 bar.
NOTE
If the oxygen content of a mix is set to 22% or above, the setting
will remain stored until changed; it does not automatically revert
back to 21%.
5.8.5. Setting the personal/altitude adjustments
The current Altitude and Personal Adjustment settings are displayed in the startup
screen when entering the DIVE mode. If the mode does not match the altitude or
personal conditions (see Section 5.9.4. Diving at altitude and Section 5.9.5. Personal
adjustments), it is imperative that you enter the correct selection before diving. Use
Altitude Adjustment to select the correct altitude and use Personal Adjustment to add
an extra level of conservatism.
