There is a valve for emergency door opening
above to the service door, turning the knob
cuts off the compressed air supply to the door
and can be opened manually.
After turning the valve knob and hence
cutting off the compressed air supply, a
warning lamp lights up and a buzzer sounds.
To return the compressed air system to normal
state, turn the knob back to initial position
and press the appropriate open door button on
the dashboard (see the following sections in
this manual: "Opening the bus from inside",
page 7).
