Connecting an external
telephone answering device
(TAD)
Sequence
You may choose to connect an external
answering device. However, when you have
an external TAD on the same telephone line
as the machine, the TAD answers all calls
and the machine “listens” for fax calling
(CNG) tones. If it hears them, the machine
takes over the call and receives the fax. If it
does not hear CNG tones, the machine lets
the TAD continue playing your outgoing
message so your caller can leave you a voice
message.
The TAD must answer within four rings (the
recommended setting is two rings). The
machine cannot hear CNG tones until the
TAD has answered the call, and with four
rings there are only 8 to 10 seconds of CNG
tones left for the fax “handshake”. Make sure
you carefully follow the instructions in this
guide for recording your outgoing message.
We do not recommend using the toll saver
feature on your external answering machine if
it exceeds five rings.
Note
If you do not receive all your faxes, reduce the
Ring Delay setting on your external TAD.
When the TAD answers a call, the LCD
shows
Telephone.
Connections
The external TAD must be connected as
shown in the previous illustration.
1
Set your external TAD to one or two
rings. (The machine’s Ring Delay
setting does not apply.)
2
Record the outgoing message on your
external TAD.
3
Set the TAD to answer calls.
4
Set the Receive Mode to
External TAD. (See Choosing the
Receive Mode on page 4-1.)
Improper Setup
Do not connect a TAD elsewhere on the
same phone line.
