Gases will not turn off automatically
Selecting a new gas will turn that gas on if it is off, but gases
will never turn off automatically.
It is important to turn off all gases you are not carrying and
or do not plan to use on the dive in the Define Gas menu to
ensure you receive accurate decompression information.
