About Fax Machines
If you’re a first-time fax machine user, fax operation might seem a little
mysterious. You’ll soon get used to the unusual fax tones on your phone line, and
be able to send and receive faxes easily.
Fax Tones and Handshake
when someone is sending a fax, the fax machine sends fax calling tones, (CNG
tones) — soft, intermittent beeps at 4-second intervals. You’ll hear them when
you dial and press S, and they continue for 30 seconds after dialing. During
that time, the sending machine must begin the “handshake” with the receiving
machine. Each time you use automatic procedures to send a fax, you are sending
CNG tones over the phone line. You’ll soon learn to listen for these soft beeps each
time you answer a phone on your fax line, so you can know if you are receiving a
fax message.
The receiving fax responds with fax receiving tones — loud, chirping sounds. A
receiving fax chirps for 40 seconds over the phone line, and the screen displays
“RECEIVE.” If your machine is set to the FAX ONLY Mode, it will answer every call
automatically with fax receiving tones. Even if the other party hangs up, your fax
machine continues to send the “chirps” for 40 seconds, and the screen continues
to display “RECEDT:.” T
o cancel the receiving mode, press H.
When your fax machine is in FAX/TEL (F/T), it answers and plays your F/T
Outgoing Aonouncement (OGM). In the F/T OGM, you'll need to tell callers
when to call back, since they cannot leave a voice message in F/T mode, or to
enter the Remote Activation Code (preset to ^ 5 1) to send a fax, See page 32 to
learn how to record the F/T OGM.
The fax “handshake" is the time in which the sending machine’s CNG tones and
the receiving machines “chirps" overlap. This must be for at least two to four
seconds, so the fax machines can understand how each is sending and. receiving
the fax. The handshake cannot begin until the call is answered, and the CNG
tones only last for 30 seconds after the number is dialed. Therefore, it’s important
for the receiving machine to answer the call in as few rings as possible.
When you have an external telephone answering device (TAD) on your fax line,
your TAD will determine the number of rings before the call is answered. Pay special
attention to the directions in the Installation chapter for connecting a TAD to your
fax machine.
