The Caller ID does not The Caller ID signal is sent ten seconds after the Call
display after the Call Waiting Signal and speaking may interfer with it. When

(For MFC 4350, MFC 4650 hold while you catch the other call. Then stop speaking
and MFC 6650MC only) until you see the Caller ID on the LCD.
I have difficulty with If you have Call Waiting, Caller ID, Call Waiting/
custom features on a single Caller ID, Ring Master, Voice Mail, an answering
line machine, alarm system or any other custom features
(For MFC 4350, MFC 4650 on a single phone line with your fax machine, it may
and MFC 6650MC only) create a problem sending or receiving fax data.
Example #1: If you are having a telephone
conversation and a fax communication signal comes
through on your Call Waiting Caller ID feature, you
can verify that the second call is a fax by switching
to it. You have the option to receive the fax call, by
asking the first caller to hang up to clear the line.
Example #2: If you are sending or receiving a fax
message while a Call Waiting Caller ID (or other
custom feature) signal comes through on the line, the
signal can temporarily interrupt or disrupt the fax
data. Brother’s ECM feature should help overcome
this problem. This condition is related to the
telephone system industry, and is common to all
devices that send and receive information on a single,
shared line with custom features. If avoiding a slight
interruption is crucial to your business, a separate line
with no custom features is recommended.
