6.2.4. Gas change and multiple breathing gas mixes

One of the special features in Suunto D6i is the possibility to set an additional nitrox mix to be used during a dive. This feature can be activated by setting the Mix2 as a Primary (or Secondary) gas, and entering other parameters in the same way as with the Mix1 gas. Mix2 settings are held until you change them (they will not return to default settings automatically). A dive is always started with Mix1. During the dive, the Suunto D6i enables you change to another enabled mix, which is within the set max- imum oxygen partial pressure. The tissue calculation during the dive is based on the mixes you have selected as Primary gases.

The Suunto D6i allows gas changes to enabled gas mixes during the dive. Gas changes are made by following the procedure below:
