Maintenance 3-3
3. Carefully remove the transceiver board by rotating it out of the chassis:
Slowly lift the board on the front edge, the side with the connector that mates with the control
head, and pull gently toward the front of the radio.
CAUTION: The thermal grease can act as an adhesive and cause the leads of the
heat dissipating devises to be over stressed if the board is lifted too quickly.

3.1 Replace the Transceiver Board
1. Inspect and if necessary, reapply thermal grease to the heatsinking pads in the chassis.
2. Before installing the connector retaining clips, ensure that the board is sitting flush on the
