My product is unable to receive faxes after I changed the number of rings to answer, Fax Speed, and DRD settings. What should I do?

  3. Scroll down and then select Restore Default Settings.
  4. Press the up or down button to select Fax Send/Receive Settings.
  5. You see a confirmation screen.
  6. Select Yes. (Select No if you want to cancel the operation.)
