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
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.
