How to Repair an FM Intercom

A wireless intercom system uses a low-powered FM radio signal to transmit and receive audio between a base station and the satellite units. If the antenna inside one of the satellite units separates from the connector on the circuit board, the intercom signal will be lost. Repair the satellite intercom unit by reattaching the antenna. Household tools are needed but no special equipment.

  Unplug the satellite intercom unit̵7;s power cord from the outlet. Remove any screws from the bottom front edges with a Phillips screwdriver. Turn the unit over. Remove the screws from the bottom with the Phillips screwdriver. Place the screws in a cup for safekeeping.
