 A. Do a visual inspection of the oxygen pressure regulator/transmitter
 (1)
 Make sure that the line end-fittings are serviceable.

 (2)
 Do a check of the oxygen pressure values on:

 -
the DOOR/OXY page on the lower ECAM display unit,

 -
the cylinder pressure gauge.

 

 (3)
 Replace the oxygen pressure regulator/transmitter (Ref. TASK 35-13-15-000-001) (Ref. TASK 35-13-15-400-001):

 -if the pressure values are not the same,
 - or if it was not replaced during the last ten months.
