Parameters Setting; Dive Program Parameters Setting - Cressi Archimede II Manual De Instrucciones

IIt is recommended that before diving at altitude, wait at least
three hours after arriving at your diving destination. This will
allow a partial release of the residual nitrogen from the body.
The atmospheric pressure at higher altitudes is lower than at
sea level. Therefore, the diver has additional nitrogen in his
body than at the lower altitudes. The excess is gradually
released and the balance re-established within a couple of
days. At this point it is important to check:
The low battery indicator. It should not be on or flashing (pic-
ture 2 a-b).
The computer display is operating. All liquid crystal segments
should be displaying.
WARNING: Should the display show the symbol of a low
battery (picture 2 a-b), the computer must NOT be used.
Additionally, should it display during a dive, the diver must
immediately surface. A battery replacement is required as
outlined in chapter 5.

2.3. - PARAMETERS SETTING.

In order to set the dive's parameters, you must depress the
central button B (Mode), and the icon relating to the program
you want to use will be shown (picture.3):

the depth meter /timer program.
NOTE: Archimedes II computer is preset on

2.3.1. - DIVE program parameters setting.

NOTE: Archimedes II computer is preset on
gram.
This is the basic program with which the Archimedes II is set.
It is possible to modify its parameters by repeatedly depres-
sing button A (
order, the dive's parameters relating to:
that is:
• PO2 Mix 1 is the partial pressure of the former of the two
Nitrox mixtures, so that Archimedes II can make its decom-
pression computations. The diver can set it on values bet-
ween 1.0 bar (included) and 1.6 bar (included), by variations
of 0.1 bar, obtained at each pressure of button C (
NOTE: By varying of max PO2 setting (picture 3), the com-
puter also indicates the maximum depth (MAX) that may be
reached with that mixture.
WARNING: Both mixtures' PO2 factory set on a basic value
, for air dives
(default) of 1.4 bar, both for air dives and for Nitrox mixture
if you want to use
dives. The diver is then following the most conservative
values recommended for sport dives. Different PO2 values
may be set as shown in chapter 3.3. The set value will be
pro-
memorized in the computer until the diver chooses another
setting.
