NOTE!
It is not possible to change between Air, Nitrox and Gauge modes before the instru-
ment has counted down the no-fl ying time.
There is one exception to this: You can change from Air to Nitrox mode even during
the no-fl ying time. When planning both air and nitrox dives during the same dive se-
ries, you should set the instrument in Nitrox mode and modify the gas mix according-
ly.
In Gauge mode, the no-fl ying time is always 48 hours.
