4 Functions during the dive
III UWATEC Aladin TEC 2G
4.1 Immersion
If the water contacts are deactivated (->47), 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, max 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 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.
4.3 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.
