Only turn-on gases you are carrying
Only turn on the gases you are actually carrying on the dive� With radio station gases,
the computer has a full picture of the OC and CC gases you are carrying and can make
informed predictions about decompression times� There is no need to turn gases off
and on when you switch from CC to OC, because the computer already knows what the
gas sets are� You should have the CC and OC gases you are actually carrying turned
on�
If you often use other gases, but not on this dive, you can enter the gas and turn it off�
You can turn gases on and off during a dive and you can also add or remove a gas dur-
ing the dive if needed�
