Very Important; Registering The Distinctive Ring Pattern; Turning Off The Distinctive Ring - Brother Model MFC-5200C User Manual

I
The MFC will only answer calls to its registered number.
I
The first two rings are silent on the fax machine. This is because
the fax must «listen» to the ring pattern (to compare it to the
pattern that was 'registered'). (Other telephones on the same line
will ring.)
I
If you program the MFC properly, it will recognize the registered
ring pattern of the 'fax number' within 2 ring patterns and then
answer with a fax tone. When the 'voice number' is called, the
MFC will not answer.

is set to MANUAL automatically. MANUAL mode will never pick up a
call by itself since it is <<Neutral>>. You can not change the receive
mode to the other mode while the Distinctive Ring is set to on.
