1. Apply 10 V AC power to the section between the point TP1 and the point TP2 . Shown in
Fig.1
2. Connect the DC+12 V to+15 V (more than 0.1 A) to the point TP5 , and the GND terminal to
the point TP4 using the DC power supply. Shown in Fig.1
3. Connect the DC -12 V to -15 V (more than 0.1 A) to the point TP3 , and the GND terminal to
the point TP4 using the DC power supply. Shown in Fig.1

● Indicated voltage values are the standard values for the unit measured by the DC electronic
circuit tester (high-impedance) with the chassis taken as standard. Therefore, there may exist
some errors in the voltage values, depending on theinternal impedance of the DC circuit tester.
No mark : Power ON
● Important safety notice:
Components identified by
mark have special characteristics important for safety.
Furthermore, special parts which have purposes of fire-retardant (resistors), high-quality
sound (capacitors), low-noise (resistors), etc. are used.
When replacing any of components, be sure to use only manufacturers specified parts shown
in the parts list.
● Caution!
IC and LSI are sensitive to static electricity.
Secondary trouble can be prevented by taking care during repair.
Cover the parts boxes made of plastics with aluminum foil.
Ground the soldering iron.
Put a conductive mat on the work table.
Do not touch the legs of IC or LSI with the fingers directly.
