:All DC voltage values

Since the voltage values of signal circuit vary to some extent according to adjustments, use them as reference values.

3.INDICATION OF PARTS SYMBOL [EXAMPLE]
In the PW board :R1209 R209 (7)Ground symbol :LIVE side ground :ISOLATED(NEUTRAL) side ground :[ ] :[ k ] :[M ] :EARTH ground :DIGITAL ground :Receptacle

4.INDICATIONS ON THE CIRCUIT DIAGRAM
(1)Resistors Resistance value No unit K M

Rated allowable power No indication :1/ 16 [W] Others Type No indication OMR MFR MPR UNFR FR (2)Capacitors Capacitance value 1 or higher less than 1 Withstand voltage No indication Others :[pF] :[µF] :DC50[V] :DC withstand voltage [V] :Carbon resistor :Oxide metal film resistor :Metal film resistor :Metal plate resistor :Uninflammable resistor :Fusible resistor :As specified

5.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.

Composition resistor 1/2 [W] is specified as 1/2S or Comp.

AC indicated :AC withstand voltage [V] Electrolytic Capacitors 47/50[Example]:Capacitance value [µF]/withstand voltage[V]
