dive computers
4.1 Immersion
If the water contacts are deactivated (->41): Switch on Aladin
®
before immersion.
If you have chosen the option "Water contacts off" ("set 1" or SmartTRAK),
Aladin
®
will turn on with a delay of up to 1 minute into the dive. This will
affect functioning of the computer. Make sure that the computer is on befo-
re starting the dive.
After immersion, starting at a depth of about 0.8 m (3 ft), all diving functions are monitored, i.e. depth
and dive time displayed, maximum depth stored, saturation of tissues calculated, no-stop time or decom-
pression prognosis determined, ascent rate controlled and displayed and the correctness of the decom-
pression procedure supervised.
4.2 TEC Setting bookmarks
During the dive you can create bookmarks in your dive profile by pressing . The logbook icon
appears for 4 seconds and an audible signal confirms the creation of the bookmark. These bookmarks will
be graphically displayed in the dive profile of SmartTRAK.
To visualize the bookmarks on the dive profile, the box "Generate bookmarks"
under "Program options" in SmartTRAK must be selected.
4.3 Dive time
The whole time spent below a depth of 0.8m (3 feet) is displayed as dive time
in minutes. The time above 0.8m (3 feet) is counted as dive time only if the
diver descends again below 0.8m (3 feet) within 5 minutes.
While the dive time is running, the colons on the right of the figures are flas-
hing in one second intervals. Maximum dive time displayed is 199 minutes.
If a dive lasts longer than 199 minutes the dive time display starts
again at 0 minutes.
4.4 Current depth / O
2
% mix
Current depth is given in 10 cm increments (1 foot).
At a diving depth of less than 0.8 m (3 ft) the display shows
<– – –>.
The O
2
% mix is diplayed as long as CNS O
2
% = 0 and no ascent speed is
indicated.
Nitrogen loading bar
TEC Half time alarm (turn around alarm)
If half of the set maximum dive time (->39) has elapsed, an audible signal
goes off and flashes for 1 minute.
TEC Set dive time has elapsed
An audible signal goes off and the dive time starts flashing.
