My product is unable to receive faxes after I changed the number of rings to answer, V.34, and DRD settings. What should I do?

• Do the following:
  1. Press the Setup button.
  2. Press or and select Restore Default Settings.
  3. Press or and select Fax Send/Receive Settings.
  You see a confirmation screen.
  4. Select Yes or No. (Select No if you want to cancel the operation.)
