(5)Voltage values

:All DC voltage values
Since the voltage values of signal circuit vary to some extent according to adjustments, use them as reference values.
4.NOTE FOR REPAIRING SERVICE
This model's power circuit is partly different in the GND. The difference of the GND is shown by the LIVE side GND and the ISOLATED(NEUTRAL) side GND.Therefore, care must be taken for the following points. (1)Do not touch the LIVE side GND or the LIVE side GND and the ISOLATED(NEUTRAL) side GND simultaneously. If the above caution is not respected, an electric shock may be caused. Therefore, make sure that the power cord is surely removed from the receptacle when, for example, the chassis is pulled out. (2)Do not short between the LIVE side GND and ISOLATED(NEUTRAL) side GND or never measure with a measuring apparatus measure with a measuring apparatus ( oscilloscope, etc.) the LIVE side GND and ISOLATED(NEUTRAL) side GND at the same time. If the above precaution is not respected , a fuse or any parts will be broken. Since the circuit diagram is a standard one, the circuit and circuit constants may be subject to change for improvement without any notice. NOTE Due improvement in performance, some part numbers show in the circuit diagram may not agree with those indicated in the part list. When ordering parts, please use the numbers that appear in the Parts List.
3.INDICATIONS ON THE CIRCUIT DIAGRAM
(1)Resistors Resistance value No unit K M Type No indication OMR MFR MPR UNFR FR (2)Capacitors Capacitance value 1 or higher less than 1 :[pF] :[F] :Carbon resistor :Oxide metal film resistor :Metal film resistor :Metal plate resistor :Uninflammable resistor :Fusible resistor :[ ] :[K ] :[M ]
Composition resistor 1/2 [W] is specified as 1/2S or Comp.
