inside the cabin of an airplane could cause
decompression sickness, as calculated by
the decompression model in the computer.

WARNING
Flying while Galileo displays NO FLY can
result in serious injury or death.
The surface interval (SURF INT) is
displayed from the moment the dive is
closed (5 minutes after surfacing), for as
long as there is remaining desaturation on
the computer.
In addition, the bar graphs at the sides
of the screen show the CNS O
2
(left bar)
and the residual nitrogen loading (right
bar). Depending on the amount of residual
nitrogen, Galileo shows the prohibited
altitude classes via grey lines inside the
stylized mountain (see section 3.6 for more
information).
1.4 Altitude alarm after
a dive
Going to altitude is in a way similar to starting
an ascent from a dive: you expose your
body to a lower partial pressure of nitrogen
and consequently you start offgassing. After
a dive, given the higher nitrogen loading
in your body, even reaching an otherwise
negligible altitude can potentially cause
decompression sickness. Consequently,
when in surface or sleep mode, Galileo
constantly monitors the ambient pressure
and uses it to evaluate your nitrogen loading
and offgassing. If Galileo notices a drop in
ambient pressure not compatible with your
current nitrogen loading, it will activate
the alarm to alert you of the potentially
dangerous situation.
1.5 No-dive warning after
a dive
If Galileo detects a situation of increased
risk (due to the potential of microbubble
accumulation from previous dives or a
CNS O
2
level above 40%), the symbol
will appear on the display together with a
suggested surface interval. This minimum
surface interval is what Galileo predicts
being necessary to reduce the number of
microbubbles and/or to reduce the CNS O
2
level below 40%.
You should not undertake a dive as long
as the no-dive warning is displayed on
the computer screen. If the warning is
prompted by microbubble accumulation
(as opposed to CNS O
2
over 40%) and
you dive anyway, you will have shorter no-
stop times or longer decompression times.
Moreover, the duration of the microbubble
warning at the end of the dive can increase
considerably.
1.6 SOS
If you stay above a depth of 0.8m/3ft for
more than 3 minutes without observing
a prescribed decompression stop, the
computer will switch into
SOS mode. Once
in SOS mode the computer will lock up
and will be inoperable as a dive computer
for 24 hours. If Galileo is used for diving
within the 24 hours of an
SOS lock, it will
automatically switch to gauge mode and
provide no decompression information.
