NOTE:
The RMT RF System Interlock, at TB30-5, provides the customer with a means of
connecting the transmitter to protection circuits, for the loads, thermal switches,
combiners, or the antenna, in the output of your system, that will Mute the
transmitter if the protection circuit opens. If the interlock is not used in the
system, a jumper from TB30-5 to TB30-15, which is ground, needs to be
connected to TB30. This jumper provides the RF System Interlock, which allows
the transmitter to go to operate. Without the jumper, the transmitter will remain
Muted.
