When the TAD answers a call, the LCD 
shows Telephone.
Connections
The external TAD must be plugged into the 
back of the MFC, into the jack labeled EXT. 
Your MFC cannot work properly if you plug 
the TAD into a wall jack (unless you are using 
Distinctive Ring).
1
Plug the telephone line cord from the 
telephone wall jack into the back of the 
MFC, in the jack labeled LINE.
2
Plug the telephone line cord from your 
external TAD into the back of the MFC, 
in the jack labeled EXT. (Make sure this 
cord is connected to the TAD at the 
TAD’s telephone line jack, and not its 
handset jack.)
3
Set your external TAD to four rings or 
less. (The MFC’s Ring Delay setting 
does not apply.)
4
Record the outgoing message on your 
external TAD.
5
Set the TAD to answer calls.
6
Set the Receive Mode to 
External TAD
.
(See Choosing the Receive Mode on 
page 4-1.)
Recording outgoing message (OGM) 
on an external TAD
Timing is important in recording this 
message.
1
Record 5 seconds of silence at the 
beginning of your message. (This allows 
your MFC time to listen for the fax CNG 
tones of automatic transmissions before 
they stop.)
2
Limit your speaking to 20 seconds.
3
End your 20-second message by giving 
your Fax Receive Code for people 
sending manual faxes. For example:
“After the beep, leave a message or 
send a fax by pressing 
51 and Start.”
Note
We recommend beginning your OGM with an 
initial 5-second silence because the MFC 
cannot hear fax tones over a resonant or loud 
voice. You may try omitting this pause, but if 
your MFC has trouble receiving, then you 
must re-record the OGM to include it.
Improper Setup
Unless you are using Distinctive Ring, 
do not connect a TAD elsewhere on the 
same phone line.
