3.1 Setting the gas mixture and ppO
2
max
Before every dive and after changing the tank, make sure that the settings
for the gas mixture correspond with the current mixture used. An incorrect
setting causes Aladin to miscalculate this particular dive. If the fraction of
oxygen is set too low this can lead to oxygen poisoning without warning. If
the value is set too high decompression sickness may occur. Inaccuracies in
the calculations are carried over to repetitive dives.
To set the gas mixture, Aladin must be in user mode (time of day display).
1. Push or until the symbol for the setting of the O
2
mixture
appears.
2. Confirm that you wish to change the displayed oxygen fraction by pushing
.
3. Change the oxygen fraction in increments of 1% by pushing or .
Aladin will display the current fraction of oxygen, the maximum partial pressure
limit (ppO
2
max) and the MOD.
4. Confirm the selected percentage with .
5. By pushing or you can change the
ppO
2
max for the chosen fraction of oxygen
down to 1.0bar. Aladin will now display the
corresponding MOD for the new ppO
2
max.
6. Confirm your ppO
2
max settings with .
• Without confirmation the display will disappear after 3 minutes and your
entries will not be accepted.
• Automatic reset of the O
2
% mix to 21% can be set with "set 1" ->31 or Smart-
TRAK between 1 and 48 hours or to "no reset" (default).
3.2 Preparation for the dive and function check
Switch on Aladin by pushing and check the test display: Are all elements
of the display activated? Do not use Aladin if the display does not show all ele-
ments. When switching on Aladin with , the test display will not appear.
Check the battery capacity before each dive ->15.
