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): , for air dives

( ) or Nitrox, mixture(s), or if you want to use

the depth meter /timer program.

NOTE: Archimedes II computer is preset on pro-

gram.

2.3.1. - DIVE program parameters setting.

NOTE: Archimedes II computer is preset on pro-

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 ( ), which allows you to select, in the following

order, the dive’s parameters relating to:

PO2 Mix 1 -> FO2 Mix 1 -> PO2 Mix 2 -> FO2 Mix 2

-> Safety Factor -> Max Depth -> OFF/ON -> DIVE

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

between 1.0 bar (included) and 1.6 bar (included), by varia-

tions 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

(default) of 1.4 bar, both for air dives and for Nitrox mixture

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

memorized in the computer until the diver chooses another

setting.
