3.1 Setting the gas mixture and ppO

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.

For dives with two gas mixtures please read page 37 for further reference.

To set the gas mixture, Aladin must be in user mode (

time of day display).
