Transceiver Board Removal

1.
Remove the screws securing the diecast cover to the chassis, using the T20 TORX™ driver
as shown in Figure 3-4.
2.
Lift the cover from the chassis.
3.
Slowly lift the transceiver board on the edge at the front of the radio (the edge that mates with
the control head) and pull gently toward the front of the radio as shown in Figure 3-5. Take
care to slide the antenna connector and power connector out of the chassis towards the front.
CAUTION: The thermal grease or pads can act as an adhesive and cause the leads of the heat dis-
sipating devices to be over stressed if the board is lifted too quickly.
