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 XP10 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.
