Why does my Panasonic Telephone not ring?
- L
  Linda ChungAug 22, 2025
  If your Panasonic Telephone does not ring, it might be because the ringer volume is set to OFF or VIBRATION. To resolve this, set it to ring by pressing the Volume Control button. Alternatively, the PS might be out of range, or the Cell Station (CS) could be busy, so move closer to the CS or try again later. Also, the radio channel might be busy, or a radio communication error might have occurred, so try again later.
