Question:	If my Neighbour installs the same system, is there a danger that his door bell push will ring our receivers
Answer:	I installed this system in my neighbor's home and want to install it my own. I cannot find, however, instructions on the process to change the transmitter frequency. The system worked right out of the box, but the instruction leaflet did talk about pairing. The implication, however, was that the pairing was just to have the receiver sound the chosen chime when the transmitter button was pushed.
