1.2 Operating modes

The functions of the Galileo computer

can be grouped into three categories,

each corresponding to a speciﬁ c 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 after 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 brieﬂ y 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 home page 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 ﬁ rst 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

heart rate (see section 2.9.5), the current

temperature, the altitude class (in form of a

stylized mountain, see section 3.6) 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-ﬂ y 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-ﬂ y time (NO FLY) is the time during

which an exposure to the reduced pressure
