Frequency Selection and Antenna Connections
Connect the Antenna
Set the Frequency
Determine an available frequency (preferably on the high end of the band) by using a good quality digital
car radio parked in your primary listening area. Select a channel on your car radio where no other radio
station is audible as well as on one channel above and one channel below. It is advisable to make this
listening test at dusk when radio reception is at best.
Use the front panel raise and lower controls to set this frequency.
Note: When using the indoor antenna, the transmitter will go through an automatic antenna calibration
routine after a frequency has been set. This routine will be automatically repeated once an hour to keep
the transmitter calibrated (an internal motor sound will be heard.)
Note: When operating the transmitter, the built in speaker can be used to monitor the broadcast signal or
manually turned off or down via the rear panel “SPEAKER VOLUME” control. The volume level setting of
the speaker volume will not affect the audio level of the broadcast signal.
Connect the indoor antenna to the rear panel lug. Locate the transmitter by a window and stretch the full
length of antenna cable out in a straight a path as possible. Set the “ANTENNA SELECT” to “BASIC.”
OR
Utilize the outdoor antenna tuning unit for extended range. Set the “ANTENNA SELECT” to “OUTDOOR and
follow the “Using the Outdoor Antenna” page in this manual for installation and tuning instructions.
Note: make sure that the transmitter is grounded either via the three prong power transformer or ground
wire connected to a screw on the rear of the unit.
