4 Functions during the dive
III UWATEC Aladin PRIME
III
4.1 Immersion
If the water contacts are deactivated (->32), 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 before start-
ing the dive.
After immersion, starting at a depth of about 0.8m (3ft), all diving functions are monitored, i.e. depth and
dive time displayed, maximum depth stored, saturation of tissues calculated, no-stop time or decompression
prognosis determined, ascent rate controlled and displayed and the correctness of the decompression
procedure supervised.
4.2 Dive time
The whole time spent below a depth of 0.8m (3ft) is displayed as dive time
in minutes. The time above 0.8m (3ft) is counted as dive time only if the diver
descends again below 0.8m (3ft) within 5 minutes.
While the dive time is running, the colons on the right of the figures are flashing
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.
4.3 Current depth / O
2
% mix
Current depth is given in 10cm increments in metric setting and 1ft increments
in imperial setting.
At a diving depth of less than 0.8m (3ft) the display shows
" – ".
The O
2
% mix is diplayed as long as CNS O
2
% = 0 and no ascent speed is
indicated.
Depth measurement is based on salt water. Therefore, Aladin
shows a slightly (3%) shallower depth than actual when diving in
fresh water. No calculation however is affected.

4.4 Maximum depth / Temperature
Maximum depth is only displayed if it exceeds the current depth by more than
1m (3ft) (maximum indicator function). If maximum depth is not displayed,
Aladin shows the temperature.
