2 RESET/TEST control slide
The crewmember presses the slide, and pushes it in the direction of the
arrow to test : the operation of the blinker, the regulator supply, system
sealing downstream of the valve ; and the regulator sealing and system
operation. Pressing the RESET control slide, after the oxygen mask has
been used, cuts off the oxygen, and the mask microphone.
3 OXY ON flag
As soon as the left flap door opens, the mask is supplied with oxygen and,
once it closes (mask still supplied with oxygen), the "OXY ON" flag appears.

1 Red grips
Squeezing the right-hand side grip unlocks the two-flap door, and enables
the harness to inflate.
2 EMERGENCY pressure selector
Use of this selector creates an overpressure, which eliminates condensation
and prevents smoke, smell or ashes from entering the mask.
-- Pressing this knob generates an overpressure for a few seconds.
-- Turning the knob, in the direction of the arrow, generates a permanent
overpressure.
Note: Overpressure supply automatically is started, when cabin altitude
exceeds 30,000 feet.

3 N/100 % SEL
Pushing up the button from underneath releases it, and it pops up to the N
(normal) position. Pressing it again returns it to 100 %.
100 % : The mask delivers 100% oxygen.
N : The mask delivers a mixture of air and oxygen, the content
of which varies depending on the cabin altitude. When cabin
altitude goes above 35,000 feet, the air inlet closes and the
user breathes 100 % oxygen.

Green : When pressure is ≥ 400 psi
Amber : When pressure is < 400 psi
An amber half frame appears, when oxygen pressure is <
1500 psi.
In this case, the flight crew must check that the remaining
quantity is not below the minimum.

psi).
3 CKPT OXY indication
It is normally white.
It becomes amber, when :
-- Pressure goes below 400 psi.
-- Low oxygen pressure is detected.
-- The overhead panel’s OXYGEN CREW SUPPLY push-button is OFF.
