1 Before Repair
1.Turn off the power supply. Using a 10 £2, 10 W resistor,
connect both ends of power supply capacitors ((3651) 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
2 Protection Circuitry
The protection circuitry may have operated if either of the
following conditions is noticed:
- 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 then the Indicated rated impedance of this unit are used.

2, Determine the cause of the problem and correct it.
3.Swltch ON the power once again.
Note:
When the protection circuitry functions, the unit will not
operate unless the power Is flrst switched OFF and ON
again.
