Connecting an external telephone
You can connect a separate telephone as shown in the diagram
below.

Whenever this phone (or TAD) is in use, the LCD shows
EXT. TEL IN USE
and, if the fax handset is lifted, an alarm
sounds.
To disconnect the call on the external phone and switch to the fax,
lift the handset and press
Hook

Connecting an external telephone answering device
(TAD)
Sequence
You may choose to connect an answering device. However, when
you have an
external
TAD on the same telephone line as the fax
machine, the TAD answers all calls and the fax machine “listens”
for fax calling (CNG) tones. If it hears them, the fax machine takes
over the call and receives the fax. If it doesn’t hear CNG tones, the
fax 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 fax 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 manual for recording
your outgoing message. We do not recommend using the toll saver
feature on your external answering machine if it exceeds four rings.
If you do not receive all your faxes, you must reset the setting
on your external TAD to four rings or less.
