SUUNTO D6 - Manual (Page 70)

6.2.4. Gas change and multiple breathing gas mixes
One of Suunto D6’s special features is the possibility to set an additional nitrox mix to
be used during a dive. This feature can be activated by setting the MIX2 to ON and
entering other parameters in the same way as with the primary gas. Mix 2 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 D6 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 mix you have selected.
The Suunto D6 allows gas changes to enabled gas mixes during the dive. Gas changes
are made by following the procedure below:
CHANGING GAS MIX. SCROLL
THROUGH ENABLED MIXES BY
PRESSING THE UP OR DOWN
BUTTONS. SELECT NEW MIX BY
PRESSING THE SELECT BUTTON.
NOTE Mix number, O
2
%, and PO
2
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.
