Connecting an external
TAD 6
You can connect an external Telephone
Answering Device (TAD) to the same line as
your machine. When the TAD answers a call,
your machine will “listen” for the CNG (fax
calling) tones sent by a sending fax machine.
If it hears them it will take over the call and
receive the fax. If it does not hear them, it will
let your TAD take a voice message and the
display will show Telephone (Ext. Tel in
Use for MFC-7470D).
The external TAD must answer within four
rings (we recommend you set it to two rings).
This is because your machine cannot hear
the CNG tones until the external TAD has
picked up the call. The sending machine will
send CNG tones for only eight to ten seconds
longer. We do not recommend using the toll
saver feature on your external TAD if it needs
more than four rings to activate it.
Note
If you have problems receiving faxes,
reduce the ring delay setting on your
external TAD to one or two rings.
Connections 6
The external TAD must be connected as
