Connect antenna:
5
Connect the supplied antenna according to the
instructions that come with the antenna. Only use an
antenna supplied by Listen. If you are connecting the
antenna directly to the top of the LT-800, you will need
to remove the rubber plug on top of the unit first. If
you are using an optional remote antenna connected
to the rear of the unit, do not connect an antenna to
the top connector. See Appendix B and C for more
information, or refer to the Listen website for remote
antenna information.
Set the RF power:
6
Set the RF POWER switch for FULL, 1/2 or 1/4. (Level
is also indicated on the front panel.) The amount of
transmitted RF power that you will need depends on
your application. If you are operating other transmit-
ters in the same environment and receivers may be
used close to the antenna, it is best to have the
transmitter's output power at its lowest level to
reduce the possibility of interference.
Power up:
7
a. Connect the LA-201 power supply to AC power.
b. Press the POWER button on the front panel.
c. Select the desired channel using the UP and
DOWN buttons.
d. If desired, lock in the selected channel by pressing
the UP and DOWN buttons simultaneously and
holding for 3 seconds.
