4 About the Protection Circuitry

The protection circuitry may have operated if either of the following conditions is noticed:
*No sound is heard when the power is supplied.
*Sound stops during a performance.
The functions of this circuitry is to prevent circuitry damage, 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 thisunit are used.
If this occurs, follow the procedure outlined below:
Press the STANDBY
/ON button, switch to STANDBY mode.
Determine the cause of the problem and correct it.
/ON button once again, supply the power.
Note:
When the protection circuitry functions, the unit will not operate unless the STANDBY
/ON button is first switched STANDBY and then ON again.
