DANGER: Do not use this instrument to dive beyond
the no decompression limits! Cressi-sub discourages the
use of this instrument for decompression dives.
In the event that you have exceeded the no decompression
limits, your Archimedes
II computer will assist with specific
information related to surfacing and related decompression
information. Upon violating the no decompression limits, the
computer will sound an alarm lasting several seconds, and
the display changes as in picture 20 , giving the diver the fol-
lowing information:
1 ( ) replaces “NDL” icon on the UFDS display, sho-
wing that no decompression has been violated and
decompression stops must be taken.
2 Depth of first decompression stage (the deepest), given
in meters (m) or feet (ft.). It may vary from a maximum of
98 ft. to a minimum of 10 ft., by decreases in increments
of 10 ft..
3 Time in minutes for first decompression stage (the deepest).
4 ( TOTAL ) icon informs the total surfacing time which inclu-
ded all decompression stops and proper ascent rates
between stops and from the last stop to the surface.
5 “DIVE. T” icon giving the total time spent while diving.
6 Graph showing the nitrogen absorbed during the dive: in
this case it is fully lit up until next “DECO” icon.

DANGER: DO NOT surface above a decompression
depth.
To avoid ascending to a depth above the decompression
depth, you should ascend to a depth slightly deeper than
the stage decompression depth requirement.
You should consider the amount of gas needed to succes-
sfully complete all decompression requirements.
During rough sea conditions, it may be difficult to comply
with the decompression stage requirements without
exceeding them. Cressi-sub recommends that shallowest
depth (nearest the surface) be at depth of about 13–16 ft.,
even though decompression will take slightly longer.
Archimedes
II will automatically calculate this.
