SUUNTO D6I - Manual (Page 92)

6.2.4. Gas change and multiple breathing gas mixes
One of the special features in Suunto D6i is the possibility to set two additional nitrox
mixes to be used during a dive. This feature can be activated by setting the Mix2 and
Mix3 as a Primary (or Secondary) gas, and entering other parameters in the same
way as with the Mix1 gas. Mix2 and Mix3 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 maximum 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:
CHANGING GAS MIX.

2
% and PO

for the mixes are shown when
scrolling. If the set PO
2
limit is exceeded, it will be shown with
the PO
2
value blinking. The dive computer does not allow you
to change to a gas whose set PO
2
is exceeded. In such a
case, the mix is shown but cannot be selected.
