5.1 End of a dive
After reaching the surface, Aladin
®
Air Z O

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 surfacing for a
short period for orientation or for a change of tank. During the five
minutes waiting time the percentage of oxygen display alternates
with maximum depth display. When the dive is closed after 5 minu-
tes in wait-mode, it is entered into the logbook and Aladin
®
Air Z O

switches into surface-mode. In surface-mode, Aladin
®
Air Z O

shows desaturation time, no fly time and CNS O

%.
If the tank is changed in this phase, you must make sure that the mixture is
exactly the same as the one previously used. If you don`t make the next dive
with an Oxy2 and you want to dive with another mixture, you must wait at
the surface for 5 minutes to allow the Aladin
®
Air Z O

to close the dive. Then
the setting of the mixture must be adjusted to the new mixture. Disregarding
this rule causes the Aladin
®

to calculate with wrong mixture data.
This can lead to injury or death.
