1. SAFETY INFORMATION

This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer.
Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair
complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty.
If you are not qualified to perform the repair of this product properly and safely; you should not risk trying to do so
and refer the repair to a qualified service technician.

- Service Precautions

1. During disassembly, be sure to turn the power off
since an internal IC might be destroyed when a
connector is plugged or unplugged.

2. Whenever the amplifier may be put into operation, a
heat sink should be mounted. ICs and transistors
may be damaged if the amplifier should be put into
operation without mounting any heat sink.

3. When operating with large output power, the heat
sink becomes very hot. Be careful not to touch it.
