measures the atmospheric pressure even while in sleep-mode.
If the computer detects a higher altitude, it switches into surface-mode auto-
matically. Desaturation time indicated at this moment refers to adaptation time
at this altitude. If diving starts within this adaptation time, Aladin

treats it as a repetitive dive, since the body still has a higher saturation.
The entire altitude range is divided into four sections which are influenced by
barometric pressure. That is why the defined altitude sections overlap on their
fringes. The altitude section is indicated at the surface, in the logbook and in
the dive planner by stylized mountains, if a mountain lake altitude is reached.
Sea level to an altitude of approximately 3000 feet is not indicated. In the fol-
lowing, you can see the approximate altitude ranges of the four sections:
