B. If the test gives the maintenance message PRAM or PRAM(10RX): - Replace the RPDR-ANNOUNCE/MUSIC (10RX) (PRAM) (Ref. AMM TASK 23-32-34000-001) and (Ref. AMM TASK 23-32-34-400-001). ____ NOTE : The upper display ON ANNOUNCE on the audio panel (123RH) of the Forward Attendant Panel (FAP) (120RH) shows a fault code. Write down the fault code and keep it with the replaced PRAM. (1) If the fault continues: - do a check for 115VAC at the PRAM (10RX) connector AC/2.

(a) If there is no 115VAC: - do a check and repair as necessary the wiring between: the PRAM (10RX) connector AC/2 and the CB 2RX, CAB COM SYSTEMS/PRAM on the panel 2000VU (Ref. ASM 23-32/01). (b) If there is 115VAC: - do a check and repair as necessary the wiring between: the PRAM (10RX) connector AC/3 and the GND (Ref. ASM 23-32/01). _ 1 If there is no ground signal: - do a check and repair as necessary the wiring between: the PRAM (10RX) connector AC/3 and the GND (AC GND), the PRAM (10RX) connector AC/4 and the GND (CHASSIS GND) (Ref. ASM 23-32/01).
C. Do the test given in Para. 3.B.
