is set to 21% oxygen (air) from the factory. If you wish to change this or any other setting, you
need to do so using the SmartTRAK software and the infrared interface. Chapter III describes the most
common settings. On the next page you will find an overview with all possible Aladin

settings and page
references.
3.1 Setting the gas mixture
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
®
ONE
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.
The setting of the gas mixture can be changed only via SmartTRAK.
• After changing the gas mixture with SmartTRAK you have to click in the top row on
the "write" icon, otherwise the setting will not be written to the Aladin
®

.
• The time to reset the O

% mix to air can be set with SmartTRAK between 1
and 48 hours or to "no reset" (default).
