possible and change the gas No. again.
After changing, you can press

Note that after 2 to 3 minutes on the gas switch screen, the dive
computer returns to the normal Dive Mode screen, keeping the
currently selected gas.
* The allowable dive depth is set to an oxygen partial pressure
of within 1.6 bar, but if it becomes 1.4 bar or more on the gas
switch screen, “PO

Regardless of multiple gases settings or single gas settings, after
diving with Nitrox settings, the settings are kept until the date

GAS2-GAS4 to OFF as default, so be sure to confirm the gas
settings before diving in Dive Plan Mode.
