HEAT CONSIDERATIONS

NOTE: NEVER remove the heatsink.

NOTE: HOT SURFACE MAY CAUSE BURNS. Ensure

that transmitter is properly ventilated and allow to cool

before touching.

Heat is an enemy of electronic components so it is impera-

tive that the transmitter is not allowed to exceed 80 degrees

C. With the heatsink removed, the temperature would rise to

125 degrees C or more, which would be destructive to the

internal components. At 125 degrees C, the unit would also

deliver a serious burn if touched.

Much of the heat is given off by the final output transistor,

which is the most critical component when it comes to heat

considerations. The heatsink is shipped mounted to the

transmitter with four 6-32 screws, and has two additional 4-

40 screws attached from the fin side of the heatsink to the

transmitter around the final output transistor. These screws

are critical for thermal conduction from the transmitter to the

heatsink. Removing these screws is not recommended.

If you plan to mount the transmitter, be sure to orient the

heatsink fins vertically for effective heat dissipation. Use one

of the recommended mounting procedures presented on

the next page.

NEVER: Fins Horizontal Fins Down

GOOD: Fins Up

BEST: Fins Vertical Fins Vertical Fins Vertical
