(1) From the back side of the front panel assembly, remove the five screws P attaching the rear cover. (See Fig.12.) (2) Release the ten joints i attaching the rear cover to the front panel assembly. (See Fig.13.) (3) Take out the switch board while lifting the switch board from the front panel assembly little by little. (See Fig.14.) Reference: Remove the volume knob from the front side of the front panel assembly at the same time. Note: Do not lose the compression springs when removing the switch board. (See Fig.14.)
