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
