3. Diving with Galileo
!
WARNING
- If Galileo receives no signal from the
transmitter for 30 seconds, an audible
sequence goes off and the message
NO
PRESSURE SIGNAL
appears on the display
for 12 seconds.
- If after another 40 seconds Galileo still has
not received any signal from the transmitter,
another audible sequence goes off and the
message
PRESSURE SIGNAL LOST
appears
for 12 seconds, after which the RBT is not
displayed any longer and the tank pressure
is replaced with – – – . Check the position
of Galileo with respect to the transmitter.
Start ascending if you don’t get a tank
pressure reading.
- If you set
PRESSURE SIGNAL
to
OFF
as described in section 2.6.8, you will not
get these warnings. In such case it is very
important that you constantly monitor the
tank pressure to avoid a low-gas supply
situation.
- If the tank pressure reaches 14bar/200psi,
the transmitter will turn off and Galileo will
not show tank pressure any longer.
Buddy tank pressure:
if your dive buddy
also uses an UWATEC Smart transmitter,
you can pair its signal to the
BUDDY
tank
designation in your Galileo. Then, as long
as you are within 1.5m/5ft of your buddy’s
transmitter, you can see the corresponding
tank pressure on the screen of your Galileo.
Oxygen bar graph:
This is the bar graph
on the left side of the display (
CLASSIC
and
FULL
configurations) and it represents
oxygen toxicity. The bar graph is made
of ten segments. The first segment lights
up at a CNS O
2
value of 5%, all other
segments light up in 10% increments
thereafter. At eight segments the CNS O
2
value corresponds to 75%, for which a
warning can be triggered (see section
2.6.2). At 95% all segments are lit. At 100%
the CNS O
2
alarm is triggered.

Nitrogen bar graph:
This is the bar graph
on the right side of the display (
CLASSIC
,
LIGHT
and
FULL
configurations). It
represents nitrogen saturation in the
leading tissue compartment. The bar
graph is made of ten segments. The first
nine segments represent gradually more
loading but still within no-stop diving; the
tenth segment represents the need for a
mandatory decompression stop.
1-6 segments: You are safely within the no-
stop zone.
7-9 segments: You are approaching
decompression.
10 segments: You have a mandatory
decompression obligation.
During a surface interval, the segments will
gradually turn off as Galileo tracks the off-
gassing of your tissues.
Tank pressure bar graph
: In
CLASSIC
and
FULL
configurations, you can choose
to replace the oxygen bar graph with a tank
pressure bar graph as described in section
2.8.2. Each segment of the graph will then
represent one tenth of the set maximum
tank pressure. In the default setting, each
segment represents 20bar/300psi.
Decompression information
:
deepest
stop
,
time at deepest stop, total ascent
time:
when Galileo calculates the need for
a mandatory decompression stop, it shows
you
AT
what depth you need to stop first
(deepest stop) and
FOR
how long (time at
deepest stop). It also gives you the total
ascent time (
TAT
). Total ascent times longer
than 199 minutes are shown as “- -”.
To emphasize the change from a
NO STOP
dive to a
DECOMPRESSION
dive, this
information is inverted in color, i.e. white
numbers over a black background.
