5.8.3. Setting the nitrox values

If set to the NITROX mode, the correct oxygen percentage of the gas in your cylinder (and additional gases) 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.

Settings for an additional mix (MIX2) are made similarly, but with the additional selection of “ON” or “OFF”.

In order to minimize the risk of error during a dive, it is highly recommended that the mixes are set in the proper order. This means that as the mix number rises, so does oxygen content, and this is the order they are usually used during the dive. Before a dive, only set to “ON” the mixes you actually have available and remember to check the set values to make sure they are correct.

The default oxygen percentage (O2%) setting is 21% (air) and oxygen partial pressure (PO2) setting 1.4 bar.

After entering values for MIX1, you can enable/disable and set an additional gas mix - MIX2.

NOTE	If MIX2 is set ON, settings for all mixes are stored until changed. If
	MIX2 has an oxygen content of 22% or greater, settings for all mixes
	are stored until changed.

5.8.4. 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.
