Note or additional information.
The MFC may be damaged or may not work
correctly if this is not observed.
Warning. Damage can result if this is not observed.
If you are a first-time fax machine user, fax operation might seem a little
mysterious. You will 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 MFC sends fax calling tones, (CNG
tones)—soft, intermittent beeps at 4-second intervals. You will hear them
when you dial and press Start, and they continue for about 40 seconds
after dialling. 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 will soon learn to listen for these soft beeps each time you
answer a phone on your MFC line, so you can know if you are about to
receive a fax message.
The receiving fax responds with fax receiving tones—loud, chirping
sounds. A receiving fax chirps for about 40 seconds over the phone line,
and the screen displays RECEIVING. If your MFC is set to the Fax
mode, it will answer every call automatically with fax receiving tones.
Even if the other party hangs up, your MFC continues to send the
"chirps" for about 40 seconds, and the screen continues to display
RECEIVING. To cancel the receiving mode, press Stop.
