REINSTALLING HEATSINK

The transmitter is shipped with the heatsink attached.

Removing the heatsink is not recommended. If, due to your

particular situation, you find that you need to reinstall the

heatsink, refer to the steps provided here.

To re-install the heatsink:

1 Ensure the chassis and heatsink surfaces are clean. If

needed, use rubbing alcohol to clean, then dry.

2 Align the transmitter and heatsink, with the back of the

transmitter mating with the front, flat surface of the

heatsink.

3 Secure the heatsink with four (4) 6-32 x 1” screws

(1-1/2” screws if using encryption model).

Install the screws from the transmitter side.

4 Make sure there is good contact between the transmitter

and the heat sink. They should be mounted flush to one

another.

5 IMPORTANT Two 4-40 screws must be installed on

the outside (fin side) of the heatsink to tighten the heat-

conductive surfaces nearest the final output power

transistor. These screws are essential for proper heat

dissipation. Do not operate the transmitter with these

screws removed. Screw must not exceed 0.125 depth

into transmitter or it will bottom-out and not provide

proper heat-conduction.

NOTE: Make sure to install all factory-provided hardware

to secure heatsink to transmitter for optimal thermal

conduction and heat dissipation. The temperature

must never exceed 80 Deg. C.

NOTE: The transmitter’s baseplate operating tempera-

ture is -30° to + 80°C. The heatsink is always required.

Removing the heatsink is not recommended as

excessive heat can destroy the device
