GALILEO 2 (G2) USER MANUAL
You can set a different ppO
2
setting for
decompression gases.
The maximum ppO
2
limit can be modified
at menu 2.4. ppO
2
max .
2 .1 .3 Trimix
If trimix is enabled the O
2
setting will appear
as follows. See chapter: Trimix to learn
how to enable this feature.
In trimix mode the oxygen fraction can be
selected from 8% to 100%.
F
NOTE: To ensure an adequate supply
of oxygen to the body, the gas used at
the beginning of the dive must contain
enough oxygen (you can use a travel
mix or one of the decompression
gases). Since the dive always starts
with tank T1, the minimum O
2
setting
for tank T1 is 18%.
WARNING
The Absolute Minimum Depth (AMD) depends
on ppO
2
min value. If the alarm depth is
shallower than 0.8m/3ft which is the dive start
depth for the G2, the alarm will not activate
before a 0.8m/3ft depth is reached! This
situation is dangerous and may lead to death
by drowning.
WARNING
Engaging in heavy work while at the surface or
at shallow depths while breathing less than a
21% oxygen (hypoxic mix) fraction may cause
a loss of consciousness and lead to drowning.
2 .1 .4 CCR
If the CCR mode is enabled the diluent tank
will appear as follows. Other tanks (T1 to
T8) can be configured as with PMG mode.
See chapter:
CCR
to learn how to enable
this feature.
Setpoint 1 can be selected from 0.2 to
0.95bar which defines the MOD.
Setpoint 2 can be selected from 1.0 to
1.6bar. Since higher values cannot be
reached at the surface, an AMD will be
calculated for the setting.
