To interrupt the switch process at any point, press so many times until the original gas is again
active; or do not confirm the gas change process.
No change of gas mixture:
If a diver fails to confirm the change of gas mixture or interrupts the switching procedure by pressing
, Subgear XP-3G displays “GAS 1” / “GAS 2”, the MOD and the oxygen fraction for 5 seconds.
