16、 5 SAFETY PRECAUTIONS The following items should be checked for continued protection of the customer and the service technician. leakage current check Beforereturningthesettothecustomer,besuretocarryouteither(1)aleakagecurrentcheckor(2)alinetochassis resistance check. If the leakage current exceeds

17、0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the set is defective. Be sure to test for leakage current with the AC plug in both polarities, in addition, when the sets power is in each state (on,offandstandbymode),ifapplicable. CAUTION Plea

18、se heed the following cautions and instructions during servicing and inspection. Heed the cautions! Cautions which are delicate in particular for servicing are labeled on the cabinets, the parts and the chassis, etc. Be sure to heed these cautions and the cautions described in the handling instructi
