SUUNTO DX - Manual (Page 92)

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.
NOTE
If no button is pressed in 15 seconds, the dive computer will go
back to the dive display without changing the gas mix. Upon as-
cent, the computer prompts you to change gas when the PO
2
level you have set for the next mix allows a gas change. The
prompt is a low priority alarm followed by the "Change gas" beep,
sounded once. The Gas mix (O
2
%:He) value blinks.
6.2.4. Set point and diluent/gas mix change in CCR mode
The Suunto DX allows both set point as well as diluent and gas mix changes to enabled
gas mixes during the dive. Enter the selection menu during the dive by long pressing
UP.
