The following chapter deals with the characteristics of diving with 2 or 3 gases. In case of using 2
gas mixtures (gas 1 and d), just ignore the parts describing the gas 2.
When diving with multiple gas mixtures, the tank pressure at TEC 3H display remains always the
one where it is connected by the hose.
Aladin TEC 3H enables you to use up to 3 different Nitrox mixtures during the same dive. Tank 1
contains the bottom mix (gas 1), tank 2 the travel mix and tank d contains the deco mix (gas d).
Switching the deco gas option on and off
In order to enable two- or three gas diving you must turn on the deco gas option in the SET 1 menu
