    1.1 GENERAL GUIDELINES TOP PREVIOUS NEXT 1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. 2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed.
  • Page 6 1.1.1 LEAKAGE CURRENT COLD CHECK TOP PREVIOUS NEXT 1. Unplug the AC cord and connect a jumper between the two prongs on the plug. 2. Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on the equipment such as screwheads, connectors, control shafts, etc.
  • Page 7 1.1.2 LEAKAGE CURRENT HOT CHECK TOP PREVIOUS NEXT 1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check. 2. Connect a 1.5kΩ, 10 watts resistor, in parallel with a 0.15μF capacitors, between each exposed metallic part on the set and a good earth ground such as a water pipe.
