U2020’s operate in the frequency range of TV channels 53 to 60.
1.) Turn the channel select switches on the receiver to an appropriate channel. With
antennas attached, and the receiver connected to a sound system (see next section for
details), turn on the power and listen for any interference from another source. If
interference is encountered, select another operating channel. If necessary, continue selecting
channels until a clear channel is found.
Caution: When operating more than one U2020 system at the same location, allow a
spacing of at least three channels between operating channels to avoid interference between
systems.
2.) Turn the Channel select switches on the associated HT-2020 or BT-2020 microphone, to
the same channel. Turn on the power switch, and verify that the system operates without
interference.
3.) Set up the proper operating levels for optimum performance as indicated under the
Setup/Operating Instructions section page 10.
*U2020’s operates in the frequency range of TV channels
