With a range of 1 - 999 minutes, the alarm can be set to your planned
bottom time, for example.
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 (O
2
%) setting is 21% (air) and oxygen partial pressure
(PO
2
) setting 1.4 bar. After entering values for MIX1, you can enable/disable and set an
additional gas mix - MIX2.

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%.
5.8.4. 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.
