WARNING:
FOR CONTINUED SAFETY THE FOLLOWING PRECAUTIONS SHOULD BE FOLLOWED
DURING SERVICING.
1.MAKE SURE POWER CORD IS DISCONNECTED BEFORE REPLACING ANY PARTS.
2.REPLACE THE PRODUCT'S TYPE AND CRITICAL PARTS AS SHOWN IN THIS DIAGRAM.
3.THE FOLLOWING TEST MUST BE IMPLEMENTED AFTER EACH REPAIR BEFORE
RETURNING IT TO CUSTOMER. USE AN OHM-METER TO MEASURE THE F.C.
RESISTANCE FROM BOTH A.C. CONDUCTORS TO ANY EXPOSED METALLIC PART
SUCH AS A SCREW HEAD. METAL INLAYS ETC. THE RESISTANCE SHOULD
BE MEASURED 10 MEGAOHMS MINIMUM.
