(2) If the test does not confirm the fault:
- remove the jumper wire between the pins B and C of the connector (7WN2-A)
- connect the connector of the handle proximity switch (7WN2)
- adjust the handle proximity switch (7WN2) with the doors checking tool (Ref. AMM TASK 52-71-00-820-002) or with the ECAM system (Ref. AMM TASK 52-71-00-820-002).
(a) If the fault continues:

B. Test
(1) On the ECAM control panel:
- push the DOOR key to get the DOOR/OXY page.
(2) Make sure that the SLIDE indication is shown on the DOOR/OXY page when the R aft escape-slide handle is in the SLIDE ARMED position.
5. Close-up
________
A. Put the aircraft back to its initial configuration.
(1) On the ECAM control panel, set the LOWER DISPLAY and the UPPER DISPLAY potentiometers to OFF.
(2) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
