Suunto D9 Watch User Manual


 
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 oxygenpercentage (O
2
%) setting is21% (air) andoxygen partialpressure
(PO
2
) setting 1.4 bar. After entering values for MIX1, you can enable/disable and set
additional gas mixes - MIX2. and MIX3.
