lAbout Transmission Distance
Transmission range is greatly affected by the local RF environment, antenna type,
power setting, frequency setting and receiver sensitivity. If the transmission range is short,
you may need to upgrade the antenna to higher gain, or install the antenna on places at
higher altitude.
Generally speaking, a rubber antenna brings up a transmission distance of around 120

FMUSER INTERNATIONAL GROUP INC. 广州市汉婷生物技术开发有限公司
14 / 16
meters, under the premise of receiving by car fm radio. Using a normal FM radio might get
about 100 meters distance. Please contact us for more and better transmission proposals.
lAbout sound quality
1. Please keep line-in volume under 50% and adjusted to a proper level when inputting into
machine.
2. If the input audio sources (such as audio from computer) include bass enhancement
mode or treble enhancement mode, please adjust the volume of transmitter to lower level,
because there is an audio amplifier built-in inside the transmitter, thus the audio output is of
high quality without distortions.
3. To ensure better listening experience, please adjust the output volume level of
transmitter to a matching grade with that of other local radio stations.
lInterference
If you hear buzzes from the transmitter, possible reasons could be from the line-in
cable or microphone, or it could be the power source, audio input device, or antenna. The
last and least possible reason is on the transmitter. Please check from the following
aspects to solve this problem:
1) Sort out all the cables on the transmitter to make sure they are not intertwined with each
other. The antenna should not be blocked by any object.
2) If the buzzes still exist, please pull out the line-in cable and Microphone wire, leave only
the antenna and power source to be connected with the transmitter, then check if the buzz
still exists.
3) If the buzzes stop after step 2, the possible reason could be the quality of the line-in
cable, or the line-in cable was intertwined with the power cord, or the audio input equipment
caused the buzz. In this case, keep the wires apart from each other should solve the
problem. We have met similar circumstances from our customers and we suggested the

FMUSER INTERNATIONAL GROUP INC. 广州市汉婷生物技术开发有限公司
15 / 16
same way to solve the problem.
4) Or you can check the audio input device, it has been testified that if the audio input
equipment is connected with a power adapter, it will cause the buzz on transmitter.
5) Another possible reason for the buzz could be on the antenna, it should be 90 degrees
vertical with tightened onto the transmitter.
6) If all checks were done as above and the buzzes are still there, the only reason should
be on the power adapter of transmitter.
