DIVE
program.
Cressi-sub computer supplies two DIVE computing pro-
grams: for Air dives (DIVE program) and for Nitrox or EAN
(Enriched Air Nitrox) dives.
NOTE: Cressi-sub computer is preset on DIVE ,
program, that is with a mixture value of 21% O2 (air) and
PO2 of 1.4. By varying the value of FO2 ’s DIVE Nitrox
computing program will start.
3.1. - AIR DIVE (
DIVE
program)
computer starts automatically "
DIVE
" program at depths
superior to 5 ft. During a no decompression dive the display will
show following information (picture 11):
1 current depth value, in meters (m) or feet (ft)
2 diving time, shown by the "DIVE T" icon
3 maximum depth reached during the dive displayed in
meters (m) or feet (ft), shown by “MAX” icon
4 still available no decompression time shown by “NDL” -
(No Decompression Limit) icon
5 indicator of segmented ascent rate
6 graph of nitrogen amount absorbed during the dive
7 graph representing CNS 02 toxicity level (see chapter
3.3.3.)
8 automatic indicator of altitude level
9 Icon of maximum depth alarm (if switched ON – see 2.7.1)
10 indicator of Nitrox mixture dive
Further important information are obtained by keeping button
A ( ) depressed by diving: they show (picture 12):
1 current PO2;
2 oxygen percentage of the selected mixture (Air if
FO2 = 21%);
3 maximum depth reached during the dive, in meters (m) or
feet (ft);
4 current temperature, in °C or °F
The display shows (
DATA
).
If you keep button C ( ) depressed, current time
will be displayed (picture 1) as follows:
1) Hours; 2) Minutes; 3) Seconds
NOTE: if the computer is used for air dives, no modifica-
tion or setting of FO2 needs to be carried out before the
subsequent dive.
At any moment of your dive, should light conditions do not
allow you an easy reading of the display, it is possible to swit-
ch on the back-illumination, by depressing button B (
). The display back-illumination will last about 5 seconds and
may be repeated any time you want. The battery consump-
tion is minimal.
