DANGER: when you ascend too fast, the risk of acci-
dent increases! Cressi-sub recommends to have a 3-5
min. safety stop at 10ft-20ft, at the end of every dive, which
will be assisted by your dive computer (see chapter 3.1.3.)
IMPORTANT: Never dive after a surface interval time
during which the (
) word was displayed! Computation
for the following dive may be invalidated by excessive
ascent rate during the previous dive.

3.1.3. - Safety Stop (
Archimede is programmed to automatically warn the diver
about the need for a safety stop, whenever diving below 30ft,
as also recommended by the most recent studies on diving
physiology. This stop shall be made at a depth from 20 to 10ft,
for the time indicated by the dive computer.
NOTA: Cressi-sub recommends to have a 3-5 min. safe-
ty stop at 10-20 ft at every dive.
The safety stop is indicated on the UFDS display with the
(
) icon (fig. 12). The display here clearly indicates the time
required for the stop in minutes and the depth expressed
either in m or in ft.
Although not compulsory, safety stops are strongly recom-
mended, especially when the maximum ascent rate has
been repeatedly violated. At this point, Archimede requires a
particularly long safety stop, which Cressi-sub advises you to
fully comply with, in order to avoid safety risks.

3.2. - Decompression Warning Alarm.
Whenever the no decompression limit indicated on the dis-
play by the NDL icon reaches 3 minutes (fig. 13), Archimede
will warn you with an audible alarm while the display will be
blinking for 6 seconds (three of which with flashing light). This
is to warn you that you have exceeded the safety curve and
that you are entering a decompression dive.

DANGER: Never use this dive computer for dives out-
side the safety limit! Cressi-sub advises you not to use this
dive computer for decompression dives.
Should you exceed the safety limits during your dive, your
Archimede Cressi-sub dive computer can give you all
decompression information required for a correct ascent and
related decompression stops. If you exceed the safety curve,
an audible alarm will be released for 3 seconds, and the
screen on the display will change to look as indicated in
Figure 14. The following information will be provided to the
diver:
1 The (
) icon on the UFDS display will be replacing the
"NDL" one, which advises that you have exceeded the
safety limits and you now have to stop for decompression;
