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.
