Common Misunderstandings about Fax Machines
This section is for people who are using a fax machine for the first time. Its purpose is to take away
the mystery. Once you understand the meaning of the new tones you will be hearing on your phone
line, you will be able to send and receive faxes with ease. This will help you troubleshoot an
occasional problem with a fax transmission, by listening through your one-way speaker to
discover the problem.
What Are Fax Tones?
First the sending machine sends CNG tones, soft intermittent beeps at 4 second
intervals. You will hear them when you dial and press the START key. CNG stands for “calling”
tones. They continue for 30 seconds after dialing: during that time the sending machine must
begin the “handshake” with the receiving machine. Each time you send an “automatic” fax
transmission, you are sending calling tones over the phone line. Learn to listen for these soft beeps
each time you answer a phone on your fax line so you will know if you are receiving a fax message.
Then the receiving machine responds with fax receiving tones, loud chirping sounds.
When a machine begins the receiving mode cycle, it will chirp for 40 seconds over the phone line.
At the same time, the fax machine’s display screen will say “receiving”. If you set your machine
to AUTO answer mode for a dedicated fax line, it will answer every call automatically with fax
receiving tones. Sometimes people will call your fax line by mistake and hang up when they hear
the shrill chirping sounds. Your machine is not malfunctioning when it continues to say
“receiving”; it must complete its 40 second cycle, even though the call was not a fax message and
the caller hung up. To take your machine out of receiving mode, press the STOP key.
The fax machine answers with a short beep when it answers in F/T mode. This can not be
changed. After the beep the fax machine listens for CNG tones. When it hears CNG tones, it
responds with receiving tones.
Why Does the Ring Change in FIT Mode?
When a double-ring (short, short) occurs after the normal long rings in the Fax/Tel
Switch (F/T mode), it means your fax machine is telling you to take over a call. The fax
machine has answered either a telephone call or a manual fax (no calling tones). When you hear
the double-ring, pick up any extension phone or the handset of your fax machine.
