On entering the decompression phase, "NO STOP" disappears, the
symbol appears and an attention beep goes off. The nitrogen loading
bar stops flashing and the 6th segment lights up (red area). The deepest
decompression stage in metres (feet) is displayed and the decompression
stop duration of the displayed stage appears in minutes. The display "7:
3m (10ft)" means that a decompression stop of 7 minutes at a depth of 3m
(10ft) has to be made.
When a decompression stop has been completed, the next (shallower)
decompression stop is displayed. When all decompression stops have
been completed, the
time reappear.
Deco stop depths deeper than 27m (90ft) are displayed as " – – : – – ".
The decompression alarm is activated if the decompression stop
is ignored. The arrow
decompression stop depth begin to flash and an audible alarm
goes off. Due to the formation of microbubbles, decompression can
increase massively if a decompression stop is ignored. When the
surface is reached during the decompression alarm, the arrow
decompression stop duration 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 (->17).
If the total (cumulative) duration of the decompression alarm is longer
than one minute, it is entered in the logbook.
Descend to the prescribed decompression stop depth immediately!
As soon as decompression stops are necessary Aladin TEC 3H shows the
total time of ascent. This includes the ascent time from the current depth to
the surface and all decompression stop obligations.
F
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 TEC 3H, make a safety stop for at least three
minutes at a depth of 5m (15ft).

4.4.12 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 to zero. It can be restarted any number
