Aladin
®
Air Z measures the atmospheric pressure even while in sleep-mode. If
the computer detects a higher altitude, it switches into surface-mode automa-
tically. Desaturation time indicated at this moment refers to adaptation time at
this altitude. If diving starts within this adaptation time, Aladin
®
Air Z 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 ft is not indicated. In the following, you can see the approxi-
mate altitude ranges of the four sections:
