1TAD
2 Protective Cap
Before you connect an external TAD 
(telephone answering device), remove the 
protective cap (2) from the EXT. jack on the 
machine.
a Set your external TAD to one or two 
rings. (The machine’s Ring Delay 
setting does not apply.)
b Record the outgoing message on your 
external TAD.
c Set the TAD to answer calls.
d Set the Receive Mode on your machine 
to External TAD. (See Receive 
modes on page 37.)
Recording an outgoing 
message (OGM) 8
a Record 5 seconds of silence at the 
beginning of your message. (This allows 
your machine time to listen for the fax 
CNG tones of automatic transmissions 
before they stop.)
b Limit your speaking to 20 seconds.
For example: “After the beep, leave a 
message.”
Multi-line connections (PABX)8
Most offices use a central telephone system. 
Brother recommends that all our Fax/MFC 
machines are connected to a discreet 
(dedicated) line. Although a particular Private 
Automatic Branch Exchange (PABX) may 
appear to work with a particular model of fax 
machine, we cannot guarantee that the unit 
will operate correctly.
While it is often relatively simple to connect a 
fax machine to a PABX, we suggest that you 
contact the company that installed your 
telephone system and ask them to connect 
the fax machine for you.
Brother does not recommend the use of a 
PABX line. PABX limitations in general can 
cause some functions of the fax machine not 
to work correctly.
