(14) AEL-H/AEL and MAN-H/MAN Circuit Boards
Note: Before replacing the MAN-H/MAN circuit board, always perform "4-9-2 EEPROM data backup and write". 1) Disconnect the two flat cables. 2) Disconnect the DRF-H/DRF circuit board (c) from MAN-H/MAN circuit board (b). 3) Remove three screws [G]. 4) Remove the AEL-H/AEL circuit board (a) that is assembled with MAN-H/MAN circuit board in the direction of the arrow: It may be difficult to remove these circuit boards, since the heat sink rubbers (e) on MAN-H/MAN circuit board may stick to the frame (d). 5) Remove the AEL-H/AEL circuit board from MAN-H/MAN circuit board in the direction of the arrow. Note: Do not scratch the surface of IC2009 or IC2010: The surfaces of IC2009 or IC2010 are silicon substrate (silicon wafer) that is semi-conducting. Scratching them could cause fault in operation. Procedure and caution for reassembly 1) Be sure to paste the two heat sink rubbers (e) on the MAN-H/MAN circuit board: Neglecting to paste the heat sink rubber could cause a fault. 2) Connect the MAN-H/MAN circuit board and AEL-H/AEL circuit board, and then attach them to the frame. If the MAN-H/MAN and AEL-H/AEL circuit boards are attached to the frame independently, a connection fault could result.
