is not used, it is in the sleep-mode.
The display does not show any information. The computer is briefly activated
once every minute to measure atmospheric pressure. The display remains
switched off. If a change in altitude is recognized, Aladin
®

mode. The increasing of the pressure from descending, automatically activates
the dive-mode.
Ready-mode:
Activation: By touching contacts B and E from sleep-mode.

After activation the Aladin
®
Air Z O

switches into ready-mode. Once in ready-
mode, the display is switched on and the set portion of oxygen is shown. In cer-
tain circumstances altitude sections are also displayed. If the pressure transmit-
ter or Oxy2 is switched on and located within transmitting distance, either the
tank-pressure or the oxygen fraction is displayed, otherwise <---> will be dis-
played.

will display its remaining battery life by percentage. Three minutes after activa-
ting the ready-mode, Aladin
