A. Installation of the Cabin Assignment Module (CAM)

Cabin Assignment Module (115RH) - Removal/Installation ** ON A/C NOT FOR ALL

(1) Clean the component interfaces and the adjacent area.
(2) Do an inspection of the component interfaces and the adjacent area.
(3) Push the CAM (4) carefully into the respective slot, the CAM slot (5), until it locks in position.

NOTE: The I-PRAM, CAM and OBRM slot has the same dimensions. Thus it is mandatory to push the Compact Flashcard into the correct slot.

(4) Make sure that the work area is clean and clear of tools and other items.
(5) Close the cover (2) and the quick-release fastener (1).
