INSTALLATION
1.
2.
You must choose a
frequency on which no other commercial station is broadcasting.
3.
4.
Connect the line, headphone or speaker output of your audio source to the
audio jack marked "IN" using the included stereo 3.5mm cable. Make sure
there is something playing and that the volume level of your audio source is
set to about medium or lower when using the headphone or speaker outputs.
Choose a transmitting frequency between 106.7 and 107.9 MHz from the
chart below and set the "FREQ" DIP switch accordingly.
Connect the adapter to the adapter jack on the unit.
Extend the transmitter's antenna fully and put it in the upright position. Now
tune any nearby FM radio to the frequency selected and you should be able to
listen to the broadcasted signal clearly.
You should adjust the volume control of your audio source to a level so that
the reception is strong and distortion free. Setting the volume too high may
distort the transmitted signal and setting it too low will weaken the output
power.
Note that immediately after changing the frequency using the DIP switch (or
upon initial power up), it may take a few seconds for the transmitter to lock-in
to the newly selected frequency.
The transmitter also incorporates a pass through stereo output jack which can
be used to connect the audio source to existing speakers or headphone.
