I Before Repair

(1)Tum off the power supply. Using a 10 Q, 10 W resistor, connect both ends oi power supply capacitors (C701, C702, C703 and C704) in order to -
discharge the voltage. V

(2') Before turning the power supply on, after completion of repair. slowly apply the primary voltage by using a power supply voltage controller to make
sure that the consumed current at 50 Hz in NO SIGNAL mode should be shown below with respect to supply voltage 230 V or 240 V.

Power supply voltage AC 230 V AC 240 V
Consumed current 50 Hz 140 ~ 400 mA 140 ~ 400 mA . .

I Protection Circuitry

The protection circuitry may have operated if either of the following conditions is noticed:
a No sound is heard when the power is switched ON.
>t< Sound stops during a performance.
The functions of this circuitry is to prevent circuitry damage if for example, the positive and negative speaker connection wires are shorted", or if
speaker systems with an impedance less than the indicated rated impedance of this unit are used. '
if this occurs, follow the procedure outlined below: .
1. Switch OFF the power.
2. Determine the cause of the problem and correct it.
3. Switch ON the power once again.

Note:
When the protection circuitry functions, the unit will not operate unless the power is first switched OFF and then ON again.
