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

especially before the first dive. All settings can be checked and
changed directly at Aladin
