Why does Doro 311c stopped ringing?

My mother has a Doro 311c telephone and it has stopped ringing audibly. As she is partially sighted this is proving a real problem for her. I can’t see anything that she may have inadvertently switched off  but hopefully it’s an easy solution




Any chance your mother turned off or minimized the ringer?

Try to increase the ring volume.

  1. Lift the handset (ignore anything you hear in the earpiece). Press and release the first button from the left under M1.
  2. Press and release #
  3. Select a ringer and melody by pressing the number keys 0-9 (please refer to the table below).
  4. Press and release the first button from the left under M1. Replace the handset.


Key/setting             Melody type           Ringer volume
1 ...............................Melody A ..............Low
2 ...............................Melody A ..............Normal
3 ...............................Melody A ..............High
