Cressi-sub reminds you that sport dives must always be kept
within the safety limits and at maximum 131 ft depth, which is
the standard maximum depth for recreational diving: if you
exceed these limits, you significantly increase your DCS risk.
1.3. - Introduction.
The Archimede Cressi-sub dive computer is a multifunctional
computer for recreational diving, providing you with informa-
tion on depth, dive times, the need for decompression, if any,
as well as on nitrogen absorption and elimination during all
dive phases, including ascent, surface interval times, and
subsequent dives.
All this information is displayed on the large UFDS (acronym
for User Friendly Display System) display, allowing for a simple
and direct 'dialogue' between the diver and the computer,
and ensuring a clear understanding of what is being done
and easy reading of displayed information.
The dive computer features a calendar clock, a versatile
memory of past dives, as well as a powerful dive simulator.
A mathematical model is also included, for use with air and
Nitrox. In this latter case, you can set all parameters required
for a Nitrox dive, from FO2 oxygen percentage, to the maxi-
mum allowable PO2 value (from 1.0 bar to 1.6 bar).
The dive computer can also be set by the user by adjusting
the unit of measure with either metric (m -°C) or Imperial sys-
tem (ft -°F).
Also, the Archimede Cressi-sub dive computer can be con-
nected with a compatible personal computer through the
Cressi-sub Interface (optional) and related software (optional).
It is extremely important that you carefully read and under-
stand this User's Manual. Otherwise,decompression sick-
ness or death may occur. Therefore, the goal is to guide you
to fully understand all the computer functions before you dive
with it.
The time and date function of the Archimede Cressi-sub dive
computer (fig. 1) is always on, with very little battery con-
sumption.
All the various functions are easily turned on with the M
(Mode), A and B buttons. As we will see below, they also turn
on when the contacts get wet during a dive. The dive pro-
gram is turned on at a depth greater than 5ft. All the functions
are clearly illustrated by the figures on the large display.
This User's Manual has been divided into 5 main topics, for a
better understanding of all dive computer functions and their
meaning:
• 1) - Introduction and Safety Rules;
• 2) - Before Dive;
• 3) - During Dive;
• 4) - On surface, after Dive;
• 5) - Care and Maintenance.
They deal with all the different dive stages. You will also find
out how easy it is to use and interpret Archimede: each dis-
play screen displays only the data your are interested in,
which refers to that particular situation.
