• FO2 Mix 1 is the oxygen percentage of the primary Nitrox
mixture (MIX1) set on Archimedes
II . The diver may vary it on
values between FO2=Air (21%) – basic setting - and FO2=50
% (included), by variations of 1% O2, obtained at each
depression of button C ( );
WARNING: Archimedes II is factory set with the primary
Nitrox mixture on Air (FO2=21%) and the second additional
mixture on Off (FO2= - -%)
NOTE: During the phase of parameters’ setting, by depres-
sing button C ( ), the computer will automatically stop on
standard Nitrox 1 mixture (EAN 32), with an oxygen percen-
tage of 32%. By keeping button C ( ) depressed, it will stop
on (Air) setting. This is to allow the FO2 operations setting to
be set quicker. Additionally, it is possible to set other FO2
values for the mixture (in increments of 1%) each time you
depress button C ( ). The constant depressing of button C
will increase the increments rapidly.
NOTE: By varying of the mixture’s oxygen percentage, the
computer indicates the maximum depth (MAX) which may
be reached with that mixture, since it depends on the PO2
value set.
• PO2 Mix 2 is the partial pressure of the latter of the two
Nitrox mixtures (MIX2) that can be set on Archimedes
II
computer. It is factory set on the value of PO2=1.4, but it may
be changed by the diver on values between 1.0 bar (included)
and 1.6 bar (included), by increments of 0.1 bar, following
each other at each depression of button C ( );
• FO2 Mix 2 is the oxygen percentage of the second Nitrox
mixture (MIX2) set on Archimedes
II computer. It is factory
set on Off (FO2= - -%) and it may be switched on only by the
diver, by depressing button C ( ), on values between FO2=Air
(21%) and FO2=99% (pure oxygen), by variations of 1%, follo-
wing each other at each pressure of button C ( )
• A Safety Factor may be set by the diver at one of three
values (SF0/SF1/SF2). It is factory set at SFO.
WARNING: In order to dive more conservatively, please
change your safety factor any time you feel that you are at
risk of decompression sickness.
• The maximum depth alarm is set on ft. 132 and OFF by the
factory (picture 4 a); it can be switched On and be modified
as well as the depth at which it will start (picture 4b), by
depressing button C ( ).
At the end of the setting, depress button B (Mode) for seve-
ral seconds; this will allow you to return to the normal display
(picture 1).
