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.
