4. Procedure
Subtask 23-73-12-420-057-A ** ON A/C NOT FOR ALL

A. Installation of the Flight Attendant Panel (FAP)
(1) Clean the component interfaces and the adjacent area.
(2) Do an inspection of the component interfaces and the adjacent area.
(3) Put the FAP (3) in position on the holder (7) and install the screws (6) and the washers (5).
(4) Adjust the FAP (3) to the middle of the cover-cutting.
(5) Tighten the screws (6).
(6) Remove the CAP-BLANKING from each electrical connector and receptacle.
(7) Make sure that all the electrical connections are clean and in the correct condition.
(8) Connect the electrical connectors (4).
(9) Make sure that the work area is clean and clear of tools and other items.
(10) Make sure that you push the CAM, the OBRM and the optional I-PRAM into the correct slots and not into one of the other slots. All slots have the same dimensions.

NOTE: The inscription THIS SIDE UP on the CAM, on the OBRM and on the optional I-PRAM must point up when they are installed.

(11) Install the Cabin Assignment Module (CAM) 115RH.
(Ref. AMM TASK 23-73-19-400-002)
(12) Install the On-Board Replaceable Module (OBRM) 116RH.
(Ref. AMM TASK 23-73-21-400-001)
(13) If an Integrated PRAM Flashcard (I-PRAM) 117RH was removed during the FAP 120RH removal procedure, install the I-PRAM again (Ref. AMM TASK 23-32-36-400-001).
(14) Close the cover (2) with the quick-release fastener (1).
