corrosion.
• If you find evidence of damage on the Control board, Display
board, or Footswitch board, replace the board. Refer to Control
Board Replacement, Display Board Replacement, or Footswitch Board
Replacement in Section 7.

replace the board only if the damage is severe. Refer to Power
Supply/RF Board Replacement in Section 7.

down. Install the five screws that secure the cover to the chassis.
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.
