Messages:
The decompression alarm is activated if the decom-
pression stop is ignored. The arrow
begins flashing and an acoustic alarm is initiated.
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
continues
flashing, in order to point to the risk of a decom-
pression accident. The SOS-mode is activated 3
minutes after the dive if corrective action is not
taken.
If the total (cumulative) duration of the decompression
alarm is longer than a minute, it is entered in the log-
book.
Response:
Descend to the prescribed decompression depth
immediately!
Total time of ascent
As soon as decompression stops are necessary, Aladin
®
Pro Ultra shows the
total time of ascent. The time of ascent to the first decompression stage and all
decompression stops are included.
The 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%).
On all dives with the Aladin
®
Pro Ultra, make a safety stop for at
least one to three minutes within the 10 to 15 feet zone.
