III Uwatec ® Aladin ® Air Z O

4.10 Increased workload warning
Messages: In case of increased workload, the Aladin ® Air Z O
2
displays a
lung symbol in the lower display and an acoustic warning occurs.
Response: In order to prevent additional saturation, reduce exertion and
breathe more slowly. See page 78.
When used with Oxy2 the Aladin ® Air Z O
2
calculates the
divers workload using the measured oxygen fraction of the inha-
lation gas mix and an automatically measured oxygen fraction of
the premixed gas.
4.11 Interruption of transmission
If no data is received for 30 seconds the display of the Aladin ® Air Z O
2
shows
the interruption of transmission signal (broken antenna) and there is an audible
warning. Without a transmission of sensible data in the following 40 seconds
<---> appears.
If the transmission between an Oxy2 and the Air Z O
2
is interrupted, the par-
tial pressure and the oxygen fraction is no longer displayed (alarm signal). The
decompression and oxygen toxicity are calculated now on the basis of the
automatically determined premix.
When used with a pressure transmitter the tank pressure and the the RBT
(Remaining Bottom Time) is no longer displayed (alarm signal).
If the transmission is interrupted then either the Oxy2 or pressure
transmitter or dive computer are not working correctly, or the position of the
sender is wrong. As soon as data are transmitted again, the computer restarts
to display the data.
