5.1 End of a dive
After reaching the surface, Aladin
®
Air Z switches into wait-mode automatically
for five minutes. This is the time span necessary to recognize the end of the
dive.
The delay allows for coming to the surface for orientation and the resumption
of the dive afterwards.
When the dive is closed after 5 minutes in wait-mode, it is entered into the
logbook and Aladin
®
Air Z switches into surface-mode.
In surface-mode, Aladin
®
Air Z shows desaturation time and no fly time.
5.2 Desaturation time
Aladin
®
Air Z is in surface-mode. The arrow DESATURATION appears; beside
it desaturation time in hours and minutes is displayed. Desaturation time is
continually indicated until the next dive or until it reaches zero. The display is
switched off to save energy 3 minutes after the last manipulation (surface-
sleep-mode). Desaturation calculations continue to be made in the background.
– In some cases, desaturation times of Aladin
®
Air Z are considerably longer than
those of other models, because the calculation model assumes reduced physi-
cal activity at the surface and calculates with shorter half-time periods.
– If desaturation time reaches the value 0, all tissues are desaturated. Aladin
®
Air Z switches into sleep-mode.
