GALILEO 2 (G2) USER MANUAL
Switching back to a gas mixture with
lower oxygen concentration
There may be situations in which you
have to switch back to a tank with lower
oxygen concentration. This can happen,
for instance, if you want to descend again
below the MOD of the higher oxygen
concentration gas (T2), or if you have run
out of T2 gas during the decompression. At
this point you can manually initiate the gas
switch by pressing and holding the BOOK
button.
The G2 will display the message SWITCH
TO GAS T1 . At this point press the SAVE
button to confirm the switch and the
ARROW button to select another gas.
The G2 will display the text SWITCH
TO GAS T1 SUCCESSFUL 4 seconds
and adapt the decompression schedule
accordingly.
Gas switch not carried out at the
planned depth
If you fail to confirm the gas change within
the 30 seconds of when the G2 suggests it,
the gas is excluded from the decompression
calculation and the decompression
schedule is adapted accordingly, basically
reflecting the fact that you will finish the dive
without using the excluded gas.
Delayed gas switch
You can catch up on a planned gas mixture
switch at any time by selecting the gas
manually. Press-and-hold the BOOK
button to start the gas switch procedure.
The G2 will show the message
SWITCH
TO GAS T2 on the display. This helps you
verify that you are performing a switch to
a safe gas. At this point you would press
the SAVE button to confirm the switch. The
G2 will display the message
SWITCH TO
GAS T2 SUCCESSFUL and adapt the
decompression schedule accordingly.
Submerging below the MOD after a
gas switch
If after having switched to gas 2 you
inadvertently drop again below the MOD
for that mixture, the MOD alarm will
immediately be activated. In this case,
you would either switch back to gas 1 or
ascend above the MOD for gas 2.
