7.2 DISASSEMBLY

- Removing the the Amp Unit

Some silicone glue has been applied

between the Heat Sink and the Sub Heat

Sink. therefore, to remove the Amp Unit

from the Heat Sink.

1. Remove ten screws C.

4. Use 2 pcs. of screw C and insert them into

the two holes marked with an arrow.

5. Alternately tighten them little by little until

the Sub Heat Sink(Sub) separates from the

Heat Sink.

Fig. 8

- Removing the Case and the Panel Units

1. Remove eight screws A and nine screws B.

2. Remove Case and Panel Units.
