Procedure
To perform the inspection, follow this procedure:
1. Remove the three screws that secure the cover to the chassis. Lift the cover off
the chassis. Save the cover and screws for reinstallation.
2. Verify that all connectors are firmly seated.
3. Inspect each board for damaged components, loose or damaged wires, cracks,
or corrosion.
If you find evidence of damage on the control board, display board, high
voltage power supply board, smart board, low voltage power supply, or
footswitch board, replace the board. Refer to Chapter 8, Replacement
Procedures for the corresponding replacement instructions.
If you find evidence of damage on the RF board, replace the board only if the
damage is severe. Refer to Chapter 8, RF Board and Heat Sink for further
instructions.
4. To reinstall the cover, slide the cover onto the chassis from the rear of the unit.
Re-install the three screws that secure the cover to the chassis. Refer to
Chapter 8, Cover for further instructions.
Caution
The generator contains electrostatic-sensitive components. When repairing the
generator, work at a static-control workstation. Wear a grounding strap when
handling electrostatic-sensitive components, except when working on an
energized generator. Handle circuit boards by their nonconductive edges. Use an
antistatic container for transport of electrostatic-sensitive components and circuit
boards.
