1.3. – Introduction.
The Cressi-sub computer is a multifunctional instrument
for sport diving. It will supply any wanted information on depth,
dive times, decompression status, ascent rate and surface
interval times between dives. Nitrogen absorption and release is
continuously processed by its sophisticated software, taking
into account the quantity of inert in the different utilized mixtures.
Such information is displayed on the instrument’s
(
User Friendly Display System ) display, allowing an easy
and direct “dialogue” between the diver and the computer,
ensuring a clear understanding of all the data needed at any
given time and a perfect readability in any situation. In addition
is equipped with a versatile dive memory (logbook).
mathematical model can make saturation and de-
saturation computations of dives carried out both with air and
with Nitrox, whose parameters can all be checked: from the
maximum allowed PO2 value (between 1.0 bar and 1.6 bar),
to the mixture’s oxygen percentage (FO2) between 21% and
50% of O2.
computer is also equipped with distinct
GAGE and FAEE
programs, which are respectively utilized in table planned dives
and apnoea dives. In both programs, the instrument supply any
needed information in a clear and extremely easy way.
Besides being a full multifunction underwater computer,
is, at the same time, a sport watch including the func-
tions of calendar, alarm, time zone etc.
Additionally, the computer may be set by the user for either
metric (m-°C) or feet system (ft-°F).
Cressi-sub underwater computer may be connected
to a compatible IBM personal computer, by means of a
Cressi-sub interface (accessory) and the related Cressi PC
Logbook software (accessory).
Please note that it is very important to read and clearly under-
stand this user’s manual; on the contrary, serious damages to
your health might occur. The present manual will lead the
user to understand all the computer’s functions before using
it while diving.
Cressi-sub computer’s watch and calendar function
are always on (see picture 1), and the related battery con-
sumption is unnoticeable.
Operational functions are easily visible either by depressing
buttons A ( ), B ( ), C ( ), D (),
which will be referred to with the letters A, B, C, D or,
underwater, when the contact E gets wet (the dive program
turns on at depths greater than 4 ft.): they are clearly illustra-
ted by the figures on the display.
NOTE: keep the contact E always clean, remove dirt or
oxide, that might cause its bad functioning, since the set
program would not automatically start. It is recommen-
ded to clean the contact. E from time to time, by rinsing it
in fresh water using a soft brush. Dry the instrument, using
a soft cloth.
