Remove the Left Front Heat Sink
1. Turn off the generator. Disconnect the power cord from the wall receptacle.
2. Remove the five screws that secure the cover to the chassis. Lift the cover off the
chassis. Save the cover and screws for reinstallation.
3. Remove the Control board.
a. Unlock the connector on the Control board and disconnect the Display board
ribbon cable from the Control board.
b. Carefully slide the Control board straight up through the slots on the heat sinks to
disconnect it from the Power Supply/RF board. Set the board aside in an antistatic
container for reinstallation.
4. Remove the three screws (one plastic and two metal) that secure the support bracket
to the heat sinks. Save the screws and bracket for reinstallation.

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.
Notice
Calibrate the generator after you install a new heat sink or replace components on the heat sink.
Component differences may affect output waveforms. Refer to Calibrating the Generator on
page 5-26, for instructions.
