Why does my Panasonic Cordless Telephone have noise and cut out?

  If noise is heard or the sound cuts in and out when using your Panasonic Cordless Telephone, it might be due to high electrical interference in the area. Try re-positioning the base unit and using the handset away from sources of interference. Moving closer to the base unit may also help. If you use a DSL/ADSL service, consider connecting a DSL/ADSL filter between the base unit and the telephone line jack.

  If you cannot hear a dial tone on your Panasonic Cordless Telephone, check that the base unit’s AC adaptor and telephone line cord are properly connected. As an alternative troubleshooting step, disconnect the base unit from the telephone line and connect the line to a known working telephone. If the working telephone operates properly, contact our service personnel to have the unit repaired. If the working telephone does not operate properly, contact your service provider/telephone company.

Why is caller information not displayed on my Panasonic KX-TG3412BX Cordless Telephone?
- S
  Shelley MartinezSep 5, 2025
  If caller information is not displayed on your Panasonic Cordless Telephone, ensure that you have subscribed to Caller ID service with your service provider/telephone company. If you have additional telephone equipment connected, such as a Caller ID box, plug the unit directly into the wall jack to eliminate potential interference. If you use a DSL/ADSL service, connecting a DSL/ADSL filter between the base unit and the telephone line jack may help. Also, try disconnecting other telephone equipment that may be interfering with the unit.
