Page 8 FM Transmitter
Antenna Orientation
Start with the antenna straight up and
fully extended. You can then orientate
the antenna to help transmit the signal
a certain direction.
To transmit audio from the FM Transmitter, it is best to find a clear FM
frequency that is not being broadcast on and free from interference.
1) Start with a radio and scan through the entire FM band (using a
digital radio will be easiest). You are looking for the largest gap in
between stations. Once you find a gap, select a frequency located
somewhere in the middle. Example: There are no stations broad-
casting between 90.1 - 93.5, select 91.5. Preferably there won’t be
a station broadcasting on either side of the frequency you have
selected.
2) Now on your FM Transmitter, turn the power
on. Use the up or down tuning arrows to
select the same frequency as on your radio.
Hold the arrows down for faster tuning.
3) With the FM Transmitter plugged into the radio or other audio
source, make sure you have adequate volume. The red LED light
indicates there is too much volume. Adjust the input level control on
the side of the unit or adjust the volume of your audio source until
the light goes off. (Refer to page 6 for location of controls.) Too
much audio may cause distortion.
Tuning
Notes On Tuning
If you are using a needle and dial radio, tune the transmitter to the
general vicinity of where you think you are on your radio. Because you
can’t match the frequency exactly, you may need to fine tune your radio
to the frequency. If you have a second radio to plug the FM Transmitter
into, you can tune the FM Transmitter until you can get the clearest
signal on your first radio.
