When checking the P.C.B.:
• Put a Cloth over the equipment. Put the P.C.B.s together with the heat sink upright on the Cloth and check them. (Fig. 6)
• Reconnect all cables (connectors) that have been disconnected.
• When connecting the flat cable, use care for the polarity.
• The P.C.B. removed from the chassis does not work because its grounding is loose. Be sure to connect the ground of
Rear Panel, MAIN (1) P.C.B. (G1001) and OPERATION (4) P.C.B. (G3001) to the chassis with a ground lead or the
like.
