INSTALLATION NOTE
CONNECTION DIAGRAM
This device must be installed in an area where there is adequate ventilation for the heat
sink.
The amplifier is not designed for continuous transmission and should not be operated in
this manner. Failure to observe this will cause the amplifier to shut down from excessive
temperature.
If the amplifier is operated in high ambient temperatures transmission times should be kept
short to avoid excessive heat sink temperature. Excessive heat sink temperature will cause
the amplifier to shut down transmission. This is indicated when the TX LED flashes.
If this occurs operation of the amplifier should be stopped and the amplifier will regain
normal operation when the temperature falls to an acceptable level. This may take more
than 5 minutes.
