The Easy Receive or Fax Detect feature allows you to receive faxes in Manual Mode by simply lifting the handset of a telephone that is on the same line as the Brother machine or connected to the Brother machine's EXT jack (socket). Simply wait until you hear the machine's receiving tones, hang up the telephone's handset, and your machine should receive the incoming fax automatically. If the machine's Easy Receive or Fax Detect function is on, then you do not have to press the Fax Start to receive a fax.
Using Manual Mode will not affect your ability to send faxes.
