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
