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

%) setting is 21% (air) and oxygen partial pressure

(PO

) 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.
