of times.
The safety stop timer can be activated under the following conditions: depth < 6.5m (21ft), no-stop
display 99 minutes.
Activate the safety stop timer by pressing
. The timer begins to count backwards and a bookmark
will be created in the dive profile. If you press again, the timer will start again from the full value.
The safety stop timer will switch off automatically if the depth exceeds 6.5m (21ft) or the no-stop phase
is shorter than 99 minutes.
4.5 Functions at the surface
4.5.1 End of a dive
After reaching the surface (<0.8m/3ft) Aladin TEC 3H remains in dive
mode for 5 minutes. The delay allows for surfacing for a short period for
orientation.
After 5 minutes the dive is closed and it is entered into the logbook. The time
of day is then displayed for 3 minutes, after which the computer turns off.
WARNING
For the calculations of the desaturation and no-fly time it is assumed
that the diver breathes air while on the surface.
4.5.2 Residual nitrogen bar graph
The segments in the residual nitrogen bar graph will gradually turn off as Aladin TEC 3H follows the
offgassing of your tissues during your surface interval. There is a 1:1 equivalence in the meaning of the
segments between diving and surface. Thus, on a repetitive dive the bar will resume from its status on
the surface just prior to the dive. There are two exceptions however:
• the uppermost segment will stay lit until the desaturation time is completely extinguished. This is
done to show that there is desaturation time left and that a dive started at this point will be logged
as a repetitive dive. If the remaining desaturation time is very short, this segment could however at
first disappear during the dive;
• during the 24 hours of an SOS-lock, all segments will stay on.
4.5.3 Desaturation time, No-fly time and No-dive warning
5 minutes after a dive Aladin TEC 3H shows the time of day, the "do not fly
time", the no-dive warning (if applicable), the current altitude range and the
prohibited altitude range (->31).
No-fly time is the time in hours that should pass before a flight and is
displayed and adjusted until the value becomes 0 hours.
WARNING
Flying while Aladin TEC 3H displays "do not fly" may lead to serious
injury or death from decompression sickness.
