FIG. 13
If the tank pressure drops below the value set
during the dive, a constant audible alarm will
sound, the word DANGER will appear on the
screen (figure 14), and the tank pressure value
will flash. The alarms can be switched off by
pressing any button. When the tank pressure
drops below 30 bar (450 psi) the alarms will be
switched on again. The alarms can be switched
off again by pressing any button.
FIG. 14
Use the <+> and <-> buttons to change the
value in increments of 10 bar (145 psi).
Press the <CENTRAL> button to record the
new setting and move on to the next section.
VOL TANK CAPACITY
This section serves to set the tank capacity.
As a function of the units of measure set
previously, entering the VOLUME setting is
done as follows (figure 15):
• liters - bar: enter the tank capacity in liters
(from 0 to 39.9 liters)
FIG. 15
• cubic feet - psi: enter the tank capacity
in cubic feet (from 0 to 399 Cuft) and the
nominal reference pressure in psi (from 0 to
4999 psi) (figures 15-1 and 15-2).
FIG. 15-1
FIG. 15-2
 WARNING
In this case, the theoretical pressure
(in psi) must be set that gives the tank the
nominal capacity in cu.ft. Do not use the
real pressure reading on the instrument.
Example: tank from 80 cu.ft. to 3000 psi.
Even if charged to a pressure other than
3000 psi, set 3000 psi on Nemo Air.
The above settings take place as follows:
The units digit will flash. Use the <+> and <->
buttons to set the desired value, and press
the <CENTRAL> button to record the selection
made and move on to the next number.
The tens digit will flash. Use the <+> and <->

the <CENTRAL> button to record the selection
made and move on to the next number.
The hundreds digit will flash. Use the <+> and
<-> buttons to set the desired value, and press
the <CENTRAL> button to record the selection

and <-> buttons to set the desired value.
If the value entered is correct, press the
<CENTRAL> button to record your selection
and return to the SET TANK menu. If not,
repeat the operation using the <+> and <->
buttons.
