To set the gas mixture, the Aladin H must
be in the dive display (showing time of day,
temperature and gas percentage):
1. Press-and-hold the right button to get
to the GAS screen, then press-and-
hold the right button again to get to the
GAS 1 O
2. Confirm that you wish to change the
oxygen fraction of gas 1 with a press-
and-hold of the right button.
3. By pressing either the left or right button
you can change the oxygen fraction
in increments of 1%. The Aladin H will
display the current fraction of oxygen,
the maximum partial pressure limit (ppO
max) and the MOD.
4. Confirm your selected percentage with
a press-and-hold of the right button.
5. Next, by pushing the left or right button
you can change the ppO
chosen fraction of oxygen down to
1.0bar. The Aladin H will now display the

21% can be set between 1 and 48
hours or to "no reset" (default).
Before every dive and after changing the tank,
make sure that the settings for the gas mixture
correspond to the current mixture being used.
An incorrect setting will cause the Aladin H
to miscalculate the dive. If the fraction of
oxygen is set too low, oxygen poisoning can
occur without warning. If the value is set too
high, decompression sickness may occur.
Inaccuracies in the calculations are carried
over to repetitive dives.
