Why is there noise and sound cutting in and out on my Panasonic KX-TG6671C Answering Machine?
- Z
  Zachary EllisSep 7, 2025
  Noise and sound cutting in and out can occur due to a few reasons: * You might be using the base unit or handset in an area with high electrical interference. Re-position the base unit and use the handset away from sources of interference. * You may be too far from the base unit. Move closer to the base unit. * If you use a DSL/ADSL service, we recommend connecting a DSL/ADSL filter between the base unit and the telephone line jack. Contact your DSL/ADSL provider for details.

  Sandy SanchezSep 4, 2025
  If you cannot hear a dial tone, the base unit’s AC adaptor or telephone line cord might not be connected. Check the connections. Alternatively, 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.
