1 Before Repairs

1.Turn off the power supply. Using a 10 Q. 10 W resistor,
connect both ends of power supply capacitors (C730,
C750) in order to discharge the voltage.

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 50/60 Hz in NO SIGNAL mode should be shown
below withrespect to supply voltage 220/230/240 V.

2 Protection Circuitry

The protection circuitry may have operated if either of the
following conditions is noticed:

o No sound is heard when the power is switched ON.
. 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 procedures 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.
