Why can't I hear a dial tone on my Panasonic Cordless Telephone?
- J
  Jordan VargasAug 15, 2025
  If you cannot hear a dial tone on your Panasonic Cordless Telephone, ensure that you are using the supplied telephone line cord, as your old telephone line cord may have a different wiring configuration. Also, check that the base unit’s AC adaptor or telephone line cord is connected properly. If you are using a splitter, remove it and connect the unit to the wall jack directly to see if the splitter is the issue. If the unit operates properly, check the splitter. 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 ID not showing on my Panasonic Cordless Telephone?
- N
  Nicholas RyanAug 30, 2025
  There are several reasons why caller information may not be displayed on your Panasonic Cordless Telephone. First, you must subscribe to a Caller ID service. Contact your service provider/telephone company for details. Also, if your unit is connected to any additional telephone equipment, remove it and plug the unit directly into the wall jack. If you use a DSL/ADSL service, consider connecting a DSL/ADSL filter between the base unit and the telephone line jack. Contact your DSL/ADSL provider for details. Finally, other telephone equipment may be interfering with this unit. Disconnect the other equipment and try again.

  devinmorrowSep 2, 2025
  If your Panasonic Cordless Telephone is not recording new messages, there might be several reasons: * The answering system could be turned off. Turn it on. * The message memory might be full. Erase unnecessary messages. * The recording time may be set to “Greeting Only”. Change the setting. * If your own greeting message is not recorded properly, callers are unable to leave a message. Record your own greeting message again. * If you subscribe to a voice mail service, messages are recorded by your service provider/telephone company, not your telephone. Change the unit’s number of rings setting or contact your service provider/ telephone company.
