Static in my panasonic telephones

A possible cause for the static in your cordless phones could be dimmer switches around the area of your phone that causes static. Turn the switches completely off (not just turned down) and see if the static leaves. You can replace the dimmers with regular switches if that clears your static. If it does not, another trace for interference: you will have to take a portable radio and turn it to AM 550 mHz and tune it to the loudest crackling noise. Carry the radio around looking for the loudest static interference. Could be a loose connection in a receptacle or panel box. Any small malfunction can cause static on wireless devices.
