devices. Our tests have shown the default volume levels of iPods, MP3  
players and other devices connected to the transmitter through the  
headphone jack does not have the signal strength required by the  
transmitter. Raising the volume of your device will increase the signal  
strength to the receiver. The blue signal LED will light when the required  
signal strength from your device is reached. We recommend that you keep  
the volume set on your iPod or MP3 player at a minimum of ¾ of full  
volume.  
When transmitting/receiving over long distances, the signal from the system  
will become weaker. This system will transmit through walls, floors and other  
obstacles However, range will be maximized by the “line of sight” placement  
with no obstacles between the transmitter and the speakers. Keep this in mind  
when placing your equipment throughout your house.
