MY phone has a problem that says OUT OF RANGE I

If you are getting a out of range error ... that tells me you need to move closer to the base station AND/OR possibly put fresh batteries in the hand piece. Out of range happens when the transmitter transmitts and does not get a response from its mate. There is the possibility that one or the other of the transmitters is not responding aand the trouble is NOT electrically related.

I dont know if this will solve your trouble ...
