than the balanced condition he/she had at the original altitude.
This extra nitrogen is gradually eliminated and the balance
resumed after a couple of days.
At this point you need to carry out a general check to see
that:
• the low battery voltage indicator is not on or blinking (fig. 2);
• the dive computer works and all the LCD segments on the
display are visible.
IMPORTANT: if the battery symbol is displayed (fig. 2),
the computer MUST NOT be used. If you see the same
symbol while diving, you have to stop and ascend to the
surface. The battery must be changed by the user, as indi-
cated in the relevant chapter (Chapter 5.1.) .
2.3. - PARAMETER SETTING.
2.3.1. - Dive Parameter Setting (
In order to set the parameters of your dive, simply press the
central M (Mode) button repeatedly, until you see the (
icon on the UFDS display, as indicated in Figure 3 (max PO2
value setting is blinking). In order to change dive parameters
keep to the following procedure:
By pressing the button A (
lowing order, dive parameters for:

) button, you select, in the fol-
where :
• PO2 is the maximum partial oxygen pressure. It can be set
by the diver with values from 1.0 bar to 1.6 bar (both values
included), with changes of 0.1 bar, whenever you press the
B (
). button;
NOTE: When you change the max PO2 value setting (fig.
3), the computer tells you the maximum depth you can
reach with Nitrox (MAX).
IMPORTANT: PO2 default setting by the manufacturer is
1.4 bar for both dives with air and Nitrox. In this way, a safe
dive is ensured in compliance with most recently recom-
mended parameters for recreational dives. However, you
can also change the PO2 as indicated in Chapter 3.4.1.
The new setting will be kept until the next reset by the
diver.
• FO2 is the oxygen percentage present in your Nitrox sup-
ply.
NOTE: by keeping the B (
)
computer will automatically stop on the standard Nitrox 1
(EAN1 32) setting - which corresponds to 32% of O2 in the
Nitrox supply - or on the (
FO2 value from 21% to 50 % can also be set, with 1%
increases at a time.
NOTE: when changing the oxygen percentage in your
Nitrox supply, the dive computer also tells you the maxi-
mum depth that you can reach with that specific supply
(MAX).
