2.3.2 - Dive planning ( ).
While on the surface it is possible to go to the Plan function
( ) in order to visualize the remaining time available at dif-
ferent depths, without having to make decompression stops
(curve time), only by primary mixture MIX1.
The values are given both for the first of a (possible) series of
dives and during the surface interval between two or more
subsequent dives; in such case, Archimedes
II takes into
account the residual nitrogen, therefore reducing the curve
times.
When the computer is set on program, by depressing
button B (Mode) twice, you view to the function ( ), as
shown by the alphanumeric display. The display will show (pic-
ture 5, air; picture 5.1., Nitrox) no decompression depths times
between 30 – 157 ft., in depth increments of 10 ft. This is obtai-
ned by depressing C ( ), or by manual depth decreases, each
of ft. 10, by depressing button A ( ).
Depress button B (Mode) for several seconds in order to get
back to the normal display (picture 1).
NOTE: PLAN function will be switched off in program
and in this case the computer shows Error.

The INFO ( ) icon on Archimedes II Cressi-sub computer
UFDS display allows you to visualize, while on the surface,
every set parameter for your dive in a quick and easy manner
(picture 6), when the computer is set on program.
By depressing button A ( ), the computer will display the set
PO2 and the relating maximum depth MAX (given in m or ft.);
the possible setting of a safety factor (SF0/1/2); the possible
oxygen percentage of the primary Nitrox (Mix 1) and the rela-
ting icon ( ), or the icon ( ) in case of an air dive. By
keeping the button depressed, the computer will display the
second mixture’s parameters (if set) in alternative sequel, and
then return to those of the primary.

The Archimedes II computer is equipped with a third program
( program or depth meter/timer) that may be used for
both apnea (free divers) divers and for the use in technical
dives with helium-based binary and ternary mixtures. In this
case, the instrument gives only the dive’s basic depth and dive
time parameters. It does not make tissue saturation and de-
saturation computation, which must be programmed and
computed by means of proper software and/or tables.
Cressi-sub reminds you that sport dives must be carried out
within the no-decompression guidelines, and at the maximum
depth of 132 ft. This is the limit of sport diving. To exceed these
limits remarkably increases the risk of decompression sickness.
