Be sure to heed these cautions and the c
4、au-tions indicated in the handling instructions.Caution concerning electric shock!(1) An AC voltage is impressed on this set, so touching inter-nal metal parts when the set is energized could causeelectric shock. Take care to avoid electric shock, by for ex-ample using an isolating transformer and g

Handle with extra carewhen the set is energized.Caution concerning disassembly and assembly!Though great care is taken when manufacturing parts fromsheet metal,
6、there may in some rare cases be burrs on theedges of parts which could cause injury if fingers are movedacross them. Use gloves to protect your hands.Only use designated parts!The sets parts have specific safety properties (fire resis-tance, voltage resistance, etc.). For replacement parts, besure t

Care is also taken with thepositions of the wires inside and clamps are used to keepwires away from heating and high voltage parts, so be sure toset everything back as it was originally.Inspect for
9、safety after servicing!Check that all screws, parts and wires removed or discon-nected for servicing have been put back in their original posi-tions, inspect that no parts around the area that has beenserviced have been negatively affected, conduct an insulationcheck on the external metal connectors
10、 and between theblades of the power plug, and otherwise check that safety isensured.(Insulation check procedure)Unplug the power cord from the power outlet, disconnect theantenna, plugs, etc., and turn the power switch on. Using a500V insulation resistance tester, check that the insulation re-sistan
