Connecting the Fax Machine
Connecting an External Telephone
Although your fax machine has a handset, you can connect a separate telephone
(or telephone answering device) directly to your fax machine.
Connect the modular plug on the telephone’s line cord to the jack labeled EXT.
on the back side of the fax machine.
Whenever this phone (or TAD) is in use, the LCD displays 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, press Hook/Hold.
Connecting an External Telephone
Answering Device (TAD)
Sequence
You may choose to connect an answering system. However, when you have an
external TAD on the same telephone line as the fax machine, the TAD answers
all calls. 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 five rings (the recommended setting is two rings).
The fax machine cannot hear CNG tones until the TAD has answered the call,
and with five rings there are only 8–10 seconds of CNG tones left for the fax
“handshake.” Make sure you carefully follow 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 five rings.
The external telephone can be cordless. Set the Receive Mode to FAX/TEL.
(See Using a Cordless External Handset , page 6-5.)
If you do not receive all your faxes, you must reset the setting on your external
TAD to four rings.
The external TAD can be cordless. Set the Receive Mode to TAD:ANSWER
MACH. .
If You Subscribe to your Telephone Company’s Distinctive Ring Service:
You may connect an external TAD to a separate wall jack only if you subscribe
to your telephone company’s Distinctive Ring service, have registered the
distinctive ring pattern on your fax machine, use that number as a fax number,
and have set your machine’s Receive mode to
MANUAL . The recommended
setting is three or four rings on the external TAD when you have the telephone
company’s Distinctive Ring Service.
