1.2 Operating modes
The functions of the Galileo computer
can be grouped into three categories,
each corresponding to a specific mode of
operation:
-
surface mode: the computer is on the
surface. In this mode you can change
settings, review your logbook, use the
dive planner, see remaining desaturation
after a dive, download to PC and much
more;
- dive mode: the computer is at a
depth of 0.8m/3ft or more. In this
mode, Galileo monitors depth,
time, temperature and performs all
decompression calculations;
- sleep mode: the computer is on the
surface for more than 3 minutes without
operation. Though the computer
appears to be turned off completely, it
is still active. Galileo checks the ambient
pressure once every 60 seconds
for uninterrupted monitoring of the
environment.
1.3 Turning on Galileo and
time of day display
To start the computer, press and hold the
right button. The screen will briefly show
the Galileo logo and then switch to the
time of day
display. If you
press
the right
button, you will skip the start-up picture
and go straight to the
time of day display.
Think of this as the homepage of your new
dive computer. This is where it all starts.
The type of information displayed in surface
mode is different depending on whether
Galileo has remaining saturation from a
recent dive or is completely desaturated.
In case of no remaining saturation, the
display looks as depicted below. The
buttons are marked, from left to right, with
“
MENU
”, “
LOG
” and “
LIGHT
”. The top of
the display shows as default the Galileo
logo, which can be replaced by the first two
lines of the owner information data (refer to
section 2.9.6 on owner information). The
time of day is shown in the middle of the
display. Underneath it, Galileo displays
various information: on the top row the
date, the current temperature, the altitude
class (in form of a stylized mountain, see
section 3.7) and the battery capacity; on
the lower row, the tank pressure, the set
oxygen concentration, the corresponding
MOD and the active MB level setting (see
section 2.3.1).
If the computer has remaining desaturation
from a recent dive, the upper portion of
the screen is replaced with the following
information: desaturation time, no-fly time,
surface interval and CNS O
2
(if applicable).
The remaining desaturation time (DESAT)
is calculated by the decompression model
in the computer. Any dive started while
there is remaining desaturation on your
computer is considered a repetitive dive,
meaning that Galileo accounts for the pre-
existing nitrogen load in your body.
The no-fly time (NO FLY) is the time
during which an exposure to the reduced
