WARNING: should the display show the symbol of a bat-
tery (picture 4 a-b), the computer must NOT be used.
Should it appear during a dive, the diver must immediately
surface.
2.4. - PARAMETERS SETTING.
To set your dive’s parameters, just depress button A
( ) in sequence until the icon of the program you
want to use appears (picture 5): DIVE, for air dive, (DIVE ) or
nitrox dives; by depressing buttons C ( ) and D
( ), in sequence, you will switch on respectively GAGE pro-
gram for a depth gauge/timer dive or FAEE program for an
apnoea dive.
NOTE: computer is preset on DIVE program.

2.4.1. - DIVE program parameters setting.
NOTE: computer is preset on DIVE program.
This is the basic program with which is preset. It is pos-
sible to modify its parameters by repeatedly depressing but-
ton A ( ) until the DIVE icon appears on the bottom.
Depress button C ( ), the DIVE icon will flash and
allow to select, in sequence, the dive parameters related to:
PO2 -> FO2 -> Safety Factor -> Max Depth -> OFF/ON -> DIVE
that is:
• PO2 is the maximum partial oxygen pressure, which may be
set by the user on values between 1.0 bar (included) and 1.6
bar (included), by variations of 0.1 bar, obtained at each
depression of button D ( );
WARNING: PO2 is preset on a basic value (default) of 1.4
bar, for both air dives and Nitrox dives. In such way, the
diver is safeguarded since he is following the most conser-
vative values recommended for sport diving. Although,
other PO2 values may be set, as shown in chapter 3.3. The
set value will be memorized in the computer until the diver
chooses a different setting.
• FO2 is the oxygen percentage of the Nitrox mixture. The
diver may vary it on values between FO2=Air (21%) – basic
setting - and FO2=50 % (included), by variations of 1%,
obtained at each depression of button D ( );
NOTE: during the phase of parameters setting, by
depressing button D ( ), the computer will automati-
cally stop on standard Nitrox 1 mixture (EAN 32), with an
oxygen percentage of 32%. By keeping button D ( ),
depressed, it will stop again on (Air) setting. This is to
quicken the setting process. Of course, you may set any
other FO2 value, by variations of 1% at each depression of
button D ( ), or by quicker increments by keeping the
button depressed.
NOTE: by varying the mixture’s oxygen percentage, the
computer indicates as well the maximum depth (MAX)
which may be reached with that mixture – it depends also
on the set PO2 value (picture 5).
• A Safety Factor may be set by the divers on three values
(SF0/SF1/SF2), obtained at each depression of button D
