Figure 6–14: Removing the main board and switch flex-circuit assembly
4. To remove the switch flex-circuit assembly from the main board, follow
these steps:
a. With the main board laying flat from the previous step, raise the switch
flex-circuit assembly to an upright position.
b. While holding the flex-circuit assembly upright, use both thumbs and
forefingers to grasp the left and right sides of the connector.
c. Carefully, alternate pulling on the left and right sides of the connector to
work it out of its socket. Do not pull one side out much farther than the
other or bent pins may result.
5. To remove the inverter board cable from the main board, unplug it.
NOTE. The BNC connectors and banana jacks are an integral part of the chassis.
If any of these connectors are defective, the chassis must be replaced.
