6.2.4. Gas change and multiple breathing gas mixes
The Suunto D9tx allows gas changes to enabled gas mixes during the dive. When the
maximum operating depth allows for a gas change, the dive computer prompts you
to change the gas. When PO
2
permits better decompression gas to be used, the dive
computer prompts it automatically if it is set as primary. Gas changes are made by
following the procedure below:
NOTE
Mix number, O
2
%, He% 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. If the PO
2
is less than 0.18 bar, the dive computer gives an alarm.
