Diving with 2 or 3 gas mixtures
NOTE:
If after the decompression calculation has readjusted itself to reect the failed switch the diver
goes again below the switch depth (MOD of gas 2 / gas d), Subgear XP-3G will revert to the
decompression calculation that considers gas 2 / gas d also, since upon ascending again the diver
will have a renewed opportunity to perform the switch once the switch depth is reached.

Belated or manually change of gas mixture:
A diver can catch up on a required change to gas 2 / gas d until he reaches the surface.
1. Initiate the switching process by pressing . Subgear XP-3G displays “GAS 2” / “GAS d” , MOD
and the oxygen fraction of gas 2 / gas d blinking for 30 seconds.
By pressing you can select “GAS 2”, “GAS d” or “GAS 1”.
2. Switch to the regulator with the selected gas mixture and start breathing.
3. Confirm the change by pressing . “GAS 2”,“GAS d” or “GAS 1” and its oxygen fraction is
displayed for 5 seconds without blinking. The decompression calculation will readjust accordingly.
Submerging again after a change to gas 2 / gas d:
If after a change to gas 2 / gas d the Maximum Operating Depth (MOD) of gas 2 / gas d is exceeded, the
ppO
2
max warning will appear ->30.
Change back to from gas 2 to gas 1 (respectively from deco gas to gas 2), which is suited for this depth,
or rise to the Maximum Operating Depth of gas 2 / gas d. Failure to do so can result in oxygen poisoning.
1. Initiate the switching process by pressing . Subgear XP-3G displays “GAS 1” / “GAS 2”, MOD
and the oxygen fraction of gas 1 / gas 2 for 30 seconds.
By pressing you can select “GAS 2”, “GAS 1” or “GAS d”.
2. Switch to the regulator with the selected gas and start breathing.
3. Confirm the change by pressing . “GAS 1” / “GAS 2” / “GAS d” and its oxygen fraction is
displayed for 5 seconds without blinking. Afterwards the decompression calculation will readjust
accordingly.
