  • Page 3: Safety Precautions

    1 Safety Precautions 1.1. General Guidelines 1. IMPORTANT SAFETY NOTICE There are special components used in this equipment which are important for safety. These parts are marked by in the Schematic Diagrams, Circuit Board Layout, Exploded Views and Replacement Parts List. It is essential that these critical parts should be replaced with manufacturer’s specified parts to prevent X-RADIATION, shock, fire, or other hazards.

  • Page 4: Protection Circuitry

    1.3. Protection Circuitry The protection circuitry may have operated if either of the following conditions are noticed: • No sound is heard when the power is turned on. • 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 the amplifier are used.
