Tuning
To transmit audio from the FM Transmitter 2, it is best to find a clear FM fre-
quency that is not being broadcast on and is free from interference.
1. To find an unused frequency in your area, you can go to www.radio-
locator.com
, click on “find unused frequencies” and enter your zip code
and state. It will list vacant frequencies as “best”, “next best”, “third best”.
You can also use a radio and scan through the entire FM band (using a
digital radio will be easiest). Look for the largest gap in between stations.
Once you find a gap, select a frequency located somewhere in the middle.
Example: If there are no stations broadcasting between 90.1 - 93.5, select
91.5. Preferably there wonʼt be a station broadcasting on either side of the
frequency you have selected.
2. Now on your FM Transmitter 2, turn the power on.
Use the Up or Down Tuning Arrows to select the
same frequency as you have set on your radio. Hold
the arrows down for faster tuning.
3. With the FM Transmitter 2 plugged into the radio, or other audio source,
make sure you have adequate volume. The Audio Input Indicator LED will
flash green in normal use. If the LED light rapidly flashes red or glows
steadily red, it is indicating there is too much volume, causing distortion.
Adjust the Input Level Control on the side of the unit or adjust the volume
of your audio source until the Audio Input Indicator LED light goes back to
flashing green. (See page 5 for location of controls.)
Notes On Tuning
If you are using an analog (needle and dial) radio, tune the transmitter to the
general vicinity of where you think you are on your radio. Because you canʼt
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 2 into, you
can tune the FM Transmitter 2 until you can get the clearest signal on your
first radio.
