- 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.
