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.
