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 (O2%) setting is 21% (air) and oxygen partial pressure (PO2) 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.
