transmitter is ideal for all stereo audio broadcasting, MP3, PC, TV, wireless speakers, game device, etc.
The FM Transmitter will not drift between stations because of our advanced stereo PLL Digital Tuner Technology.
The FM Transmitter use the control panel buttons to control the frequency that it broadcasts on so if the power is lost and
then restored it will begin broadcasting back on that exact same frequency. This avoids any need to reset the FM
Transmitter back t o the frequency you originally wanted.
We use a switch to turn the transmitter on and off. This allows the transmitter to automatically turn back if power were to
be lost and then restored.
The FM Transmitter is designed to operate non-stop 24/7.
The higher you place the antenna the farther you will transmit.
Complete easy to follow plug & play instructions are included plus tips on getting the best distance possible.
If you can match a good antenna to the FM transmitter, the effect will be better. The transmission range depends on
many factors. The true distance is based on the sensitivity of the receiver, antenna of the receiver, and the building and
other obstructions, which are between the transmitter and receiver. And the distance will much mor e in countryside.

1) If the FM Transmitter does not function normally,
• Please check whether all wires/ cables being connected tight and correct.
• If the product cannot be powered on, check whether the AC adapter works and connects properly.
2) If music output from the radio is distorted (not clear),
• First, reduce volume from iPod or audio player to medium or lower volume range, and then turn up volume from radio to
desired level. The music sound quality should improve.
• If the pervious method does not improve the music sound quality, it means the problem may be due to frequency
interference. Then you need to switch to other channel.
3) If the volume output from the radio is too loud when the FM Transmitter is not being in use,
• When FM Transmitter is in used, desired volume output level from the radio is typically higher than without using FM
Transmitter. To prevent the volume output too loud when the FM Transmitter is not being in use, you can decrease the
radio volume and increase the iPod or audio player volume as long as the sound from the radio remains clear.
4)
If music output from the radio have current acoustic interference,
• Try to change the location of the transmitter , or change the location of the power supply, or change the location of the
audio line . Power supply must be away from the transmitter at work.
