3、nfirm the specified insulation resistance between power cord plug prongs and externally exposed parts of the set is greater than 10 Mohms, but for equipment with external antenna terminals (tuner, receiver, etc.) and is intended for C or A, specified insulation resistance should be more than 2.2 Moh

4、ms (ground terminals, microphone jacks, headphone jacks. line-in-out jacks etc.) . PRECAUTIONS DURING SERVICING 1. 2. BO 008 SDS Parts identified by the A symbol parts are critical for safety. Replace only with parts number specified. In addition to safety, other parts and assemblies are specified f

5、or conformance with such regulations as those applying to spurious radiation. These must also be replaced only with specified replacements. Examples: RF -converters, tuner units, antenna selector switches, RF cables, noise blocking capacitors, noise blocking filters, etc. Use specified internal wiri

6、ng. Note especially: 1) Wires covered with PVC tubing 2) Double insulated wires 3) High voltage leads Use specified insulating materials for hazardous live parts. Note especially: 1) Insulation Tape 2) PVC tubing 3) Spacers (Insulating Barriers) 4) Insulation sheets for transistors 5) Plastic screws

7、 for fixing microswitch (especially in turntable) When replacing AC primary side components (transformers, power cords, noise blocking capacitors, etc.), wrap ends of wires securely about the terminals before soldering. o c Observe that wires do not contact heat producing parts (heatsinks, oxide met

8、al film resistors, fusible resistors, etc.). Check that replaced wires do not contact sharp edged or pointed parts. Also check areas surrounding repaired locations. Use care that foreign objects (screws, solder droplets, etc.) do not remain inside the set. VOLTAGE CONVERSION Each machine is preset a

9、t factory according to its destination, but some machines can be set to 110V/120V or 220V/240V as required. If your machines voltage can be converted: Before connecting the power cord or assembling the platter turn the Voltage Selector located on the top of the cabinet with a screwdriver until the c

10、orrect voltage is indicated. Models for USA, Canada, Europe, UK and Australia are not equipped with this facility. NOTE: Cycle conversion is unnecessary since AP-M50 use a DC motors.
