3 Protection Circuitry
The protection circuitry may have operated if either of the following conditions is noticed:
l
No sound is heard when the power is switched ON.
l
Sound stops during a performance.
The function 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 outlines 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.
