III

The decompression alarm is activated if the

decompression stop is ignored. The arrow ,

the decompression stop duration and decompres-

sion stop

depth begin to flash and an audible alarm

goes off.

Due to the formation of microbubbles decompression can increase massive-

ly if a decompression stop is ignored. When the surface is reached during

the decompression alarm, the arrow

, the decompression

stop

durati-

on and decompression stop depth

continue flashing, in order to point to

the risk of a decompression accident. The SOS mode is activated 3 minutes

after the dive if corrective action is not taken (->14).

If the total (cumulative) duration of the decompression alarm is longer than

a minute, it is entered in the logbook.

Descend to the prescribed decompression stop depth immediately!

Total time of ascent

As soon as decompression stops are necessary

Aladin

shows the total time of

ascent. This includes the ascent time from the current depth to the surface and all

decompression stop obligations.

The total time of ascent is calculated on the basis of the prescribed

ascent rate. Total time of ascent can be subject to change if the ascent

rate is not ideal (100%).

Ascent time greater than 99 minutes is displayed as <– –>.

On all dives with Aladin

, make a safety stop for at

least three minutes at a depth of 5 m (15 feet).

4.11 Safety stop timer

The safety stop timer displays the time span a diver should spend at the safety

stop depth at the end of the dive. The timer is activated by the diver and counts

back from 3 minutes (default) to zero. It can be restarted any number of times.

TEC The duration of the timer can be set between 1 and 5 minutes.

The safety stop timer can be activated under the following conditions:

Depth

< 6.5 m

(21 ft)

, no-stop display 99 min., gauge mode is switched off.

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 6.5 m

(21 ft) or the no-stop phase is shorter than

minutes.

WARNING

5 Functions at the surface

5.1 End of a dive

After reaching the surface (<0.8 m/3 ft) Aladin

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.

For the calculations of the desaturation and no-fly

time it is assumed that the diver breathes air while

on the surface.
