Bias Adjustment

1. Rotate fully the bias adjusting semi-fixed resistors (RV500,

RV600) to the MIN position (counterclockwise).

2. Connect a digital voltmeter to the CN500 and CN600.

3. Set the slidack to 0 V, and press the Ubutton (ON) on the

set.

4. Raise gradually the slidack voltage up to the rated voltage

(230 V).

5. At this time, confirm that the SP relay is turned on (it will

click), and at the same time, the LED on the Ubutton changes

from red to green.

6. Adjust the RV500 and RV600 so that a reading of digital volt-

meter is 10 mV ± 2 mV.

7. Return the slidack to 0 V, and press the Ubutton (OFF) on

the set.

(In addition to this, the necessary note is printed in each block.)

Note on Schematic Diagram:

• All capacitors are in µF unless otherwise noted. pF: µµF

50 WV or less are not indicated except for electrolytics

and tantalums.

• All resistors are in Ωand 1/4W or less unless otherwise

specified.

•2: nonflammable resistor.

•5: fusible resistor.

•C: panel designation.

Note on PrintedWiring Boards:

•X: parts extracted from the component side.

•b: Pattern from the side which enables seeing.

• Indication of transistor.

•U: B+ Line.

•V: B– Line.

•H: adjustment for repair.

• Voltages and waveforms are dc with respect to ground

under no-signal conditions.

no mark: POWER ON

• Voltagesare taken with aVOM(Inputimpedance10 MΩ).

Voltage variations may be noted due to normal produc-

tion tolerances.

• Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal produc-

tion tolerances.

• Circled numbers refer to waveforms.

• Signal path.
