Protection Circuitry
The protection circuitry may have operated if either of the foliow-
ing conditions ts noticed:
® No sound is heard when the power is switched ON.
(The current drive indicator of the operation
indicator is not
illuminated.)
* Sound stops during a performance.
The function of this circuitry is to prevent circultry damage if. for
