transmission distance more than 300 meters (In the line of 
sight

field, open land). 

This transmitter is ideal for al  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 
to the frequency you original y 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 be much more in countryside. 

 Only for reference, also the covering distance is 

concern with the antenna and environment. 

TR508 FM Transmitter, it's owners, and employees accept no 
responsibility whatever for any consequences arising from the use
