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 Subgear XP-3G 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 2 or 3 gas mixtures please read page 59 for further reference.
For CCR dives please read page 66 for further reference.
