I have just recently purchased a house that has a Rittenhouse Model 7300 Intercom system that does not work. I am trying to find a schematic for it. I know that it is an old system, but would like to use it to monitor my young children. Any help would be appreciated.Thank you.Eric Hoffman

Installed in 1987 when we built the house. Has begun sporadic multiple, single dings, all hours, day and night. I have replaced, back up battery and fuse in motor. Now makes a fairly loud buzzing sound also. Thoughts?
