MB level L1-L5
3.2.2 Alarms
Alarms are given to the diver visually by

3.3.1 Setting the gas mixture and
ppO max
2
WARNING
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 2G 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.
For dives with two gas mixtures please
read page 48 for further reference.
To set the gas mixture, Aladin 2G must be
in user mode (time of day display).
