Be careful when disassembling and servicing.
Some chassis components may have sharp edges.

1. This section describes the disassembly procedures for all the major printed circuit boards and main components.
2. Before the disassembly process was carried out, do take special note that all safety precautions are to be carried out.

(Ensure that no AC power supply is connected during disassembling.)

3. For assembly after operation checks or replacement, reverse the respective procedures.

Special reassembly procedures are described only when required.

4. Do take note of the locators on each printed circuit board during reassembling procedures.
5. The Switch Regulator IC may have high temperature after prolonged use.
6. Use caution when removing the top cabinet and avoid touching heat sinks located in the unit.
