WARNING
- Diving with Nitrox may only be
attempted by experienced divers after
proper training from an internationally
recognized agency.
- Before every dive and after changing
the tank, you must make sure that the
set oxygen concentration in Quad Air
corresponds to the oxygen concentration
in the tank. Setting the wrong oxygen
concentration can lead to serious injury
or death.

2.2.1.1. LGHt (BACKLIGHT)
Quad Air has a backlight which can be
activated in case of low ambient light. The
backlight is activated by pressing and holding
either of the upper buttons. During a dive, the
backlight will stay on for the duration defined
in this menu. You can choose between 1 and 10
seconds.
NOTE
- The backlight consumes battery energy:
the longer the backlight stays on, the
less your battery will last.
- If the low battery warning is activated,
the backlight will be disabled.
In surface mode, the backlight can be activated
by pressing and holding either of the upper
buttons. The backlight will stay on for 6
seconds, unless you go into any menu, in which
case it will stay on until you return to the pre-
dive display or after one minute of no button
operation (at which point Quad Air turns off).
2.2.1.2. P FACt (P FACTOR)
Quad Air allows you to set an additional
personal safety factor for those circumstances
in which you want to be especially cautious,
such as after a long period of inactivity or

menu you can choose between the standard
algorithm (P0), a more conservative version
(P2) or an intermediate one (P1). On the pre-
