About a fax machine Adding a fax machine
You may wish to use a fax machine with your
phone. Choose line 3 or 4 for the fax machine,
and connect it according to the manufacturer’s
instructions for installation and use.
• That line’s telephone number is your fax
number.
• The same line can be used for outgoing calls,
(incoming faxes get a busy signal when the line
is in use).
• Set your fax machine to answer on the first ring
(follow manufacturer’s instructions).
• To prevent the fax line from ringing at all the
extensions, turn the ringer off for that line at
other extensions (see RINGER ON/OFF on
page 33).
NOTES:
1. Do not connect a fax machine to line 1. Doing
so interrupts the telephone’s intercom data
channel.
2. If you are using a fax switch, or a fax machine
with a built-in fax switch, see Using a fax
switch, below.
Using a fax switch
A fax switch lets the telephone know, before the
phone rings, whether an incoming call is a voice
call or a fax call. Some fax machines have a built-
in fax switch. Using a fax switch may affect the
operation of the LINE lights or other system
features.
