ALADIN ALADIN AIR Z, Operating Manual, Page: 48 / 86

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 the diver to come to the surface for orientation and to resume
the dive afterwards.
When the dive is closed after 5 minutes in wait-mode, it is entered into the log-
book 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
When <DESATURATION> appears, the Aladin
®
Air Z is in surface-mode.
Desaturation time in hours and minutes is displayed next to that. Desaturation
time is continually indicated until the next dive or until it reaches zero. The dis-
play is switched off to save energy three minutes after the last manipulation is
made (surface-sleep-mode). Desaturation calculations continue to be made in
the background.
• In some cases, desaturation times with the Aladin
®
Air Z are longer than those
of other models. This is because the calculation model assumes reduced physi-
cal activity at the surface (therefore less nitrogen off gassing) and uses shorter
half-times.
• If desaturation time reaches zero, the “tissue“ models of the Aladin
®
Air Z are
desaturated and it switches into the sleep-mode.
