WARNING
The following ascent rates correspond to the 100% value in Aladin

Optimal ascent rate varies depending on depth between 7 and 20 m/min (23
and 66 ft/min). It is displayed in the lower right corner as a percent of the
reference variable ascent rate.
WARNING
WARNING
The prescribed ascent rate must be observed at all times! Exceeding the pre-
scribed ascent rate can lead to microbubbles in the arterial circulation which
can lead to serious injury or death due to decompression sickness.
• In case of an improper ascent Aladin
even within the no-stop phase because of the danger of microbubble formation.
• The decompression duration necessary for the prevention of microbubbles can
increase massively if the ascent rate is exceeded.
• From great depth a slow ascent may cause heightened saturation of tissues
and an extension of both decompression duration and total ascent time.
At shallow depth, a slow ascent may shorten the decompression duration.
• Display of the ascent rate has the priority over "CNS O
• Excessive ascent rates for longer periods are entered in the logbook.

If the ascent rate is greater than 100% of the set
value, the black arrow "SLOW" appears.
Reduce ascent rate.
If the ascent rate exceeds 140%, the arrow "SLOW"
starts flashing.
Reduce ascent rate.
