Chapter 3 Maintenance & Disassembly
3.1.03 Maintenance Precautions
- Do not disassemble the unit if it is operating normally.
- Before starting disassembly and assembly, always power OFF the unit and detach
the AC power cord.
- Detach the interface cable, if installed.
- Do not remove parts unnecessarily. Try to keep disassembly to a minimum.
- Use the recommended maintenance tools.
- When disassembling, follow the listed sequence. Failure to follow the correct sequence may
result in damaged parts.
- Since screws, collars and other small parts are easily lost, they should be temporarily attached
to the original positions.
- When handling circuit boards use extreme care. Integrated circuits (microprocessors, ROM, and
RAM) can be destroyed by static electricity.
- Do not place printed circuit boards directly on conductive surfaces.
- Follow the recommended procedures when replacing assemblies and units.
