5.7.3. 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 maximum operating depth (MOD),
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 enable the mixes you actually have available, and remember to check the
set values to ensure they are correct.
