19、ing the set to the customer, be sure to carry out either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 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 te
20、st for leakage current with the AC plug in both polarities, in addition, when the sets power is in each state (on, off and standby mode), if applicable.CAUTION Please heed the following cautions and instructions during servicing and inspection. Heed the cautions!Cautions which are delicate in partic
21、ular 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 instructions. Cautions concerning electric shock!(1) An AC voltage is impressed on this set, so if you touch internal metal parts when the set is
22、energized, you may get an electric shock. Avoid getting an electric shock, by using an isolating transformer and wearing gloves when servicing while the set is energized, or by unplugging the power cord when replacing parts, for example.(2) There are high voltage parts inside. Handle with extra care
23、 when the set is energized. Caution concerning disassembly and assembly!Through great care is taken when parts were manufactured from sheet metal, there may be burrs on the edges of parts. The burrs could cause injury if fingers are moved across them in some rare cases. Wear gloves to protect your h
24、ands. Use only designated parts!The sets parts have specific safety properties (fire resistance, voltage resistance, etc.). Be sure to use parts which have the same properties for replacement. The burrs have the same properties. In particular, for the important safety parts that are indicated by the
25、 z mark on schematic diagrams and parts lists, be sure to use the designated parts. Be sure to mount parts and arrange the wires as they were originally placed!For safety seasons, some parts use tapes, tubes or other insulating materials, and some parts are mounted away from the surface of printed c
