About Fax Machines
If youÕre a first-time fax machine user, fax operation might seem a little
mysterious. YouÕll soon get used to the unusual fax tones on your phone
line, and be able to send and receive faxes easily.

Introduction 
						

							2CHAPTER ONE
Fax Tones and Handshake
When someone is sending a fax, the fax machine sends fax calling tones (CNG
tones)Ñsoft, intermittent beeps at 4-second intervals. YouÕll hear them when
you dial and press 
Start, and they continue for about 40 seconds after dialing.
During that time, the sending machine must begin the ÒhandshakeÓ with the
receiving machine. Each time you use automatic procedures to send a fax, you
are sending CNG tones over the phone line. YouÕll soon learn to listen for these
soft beeps each time you answer a phone on your fax line, so you know if you
are receiving a fax message.
The receiving fax responds with fax receiving tonesÑloud, chirping sounds.
A receiving fax chirps for about 40 seconds over the phone line, and the
screen displays RECEIVE. If your fax 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 ÒchirpsÓ
for about 40 seconds, and the screen continues to display ÒRECEIVE.Ó To
cancel the receiving mode, press 
Stop.
When your fax machine answers in FAX/TEL Mode, the fax machine listens
for CNG tones and then responds with receiving tones.
The fax ÒhandshakeÓ is the time in which the sending machineÕs CNG tones
and the receiving machines ÒchirpsÓ overlap. This must be for at least 2 to 4
seconds, so the 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 about 40 seconds after the number is dialed. Therefore, itÕs
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.
ECM (Error Correction Mode)
The Error Correction Mode (ECM) is a way for the fax machine to check
the integrity of a fax transmission while it is in progress. ECM
transmissions are possible only between machines that both have the ECM
feature. If they do, you may send and receive fax messages that are
continuously checked for their integrity.
Sufficient memory must be available in your fax machine for this feature to
work.

Caution
1Never install telephone wiring during a lightning storm.
2We recommend that this product be used with a surge protection device
to protect the product against lightning storms.
3Never install a telephone jack in a wet location unless the jack is
specifically designed for a wet location.
4Never touch telephone wires or terminals that are not insulated unless
the telephone line has been disconnected at the network interface.
5Use caution when installing or modifying telephone lines.
6Avoid using a telephone (other than a cordless type) during an electrical
storm. There may be a remote risk of electric shock from lightning.
7Do not use the telephone to report a gas leak in the vicinity of the leak.
8For PLUGGABLE EQUIPMENT, the socket-outlet should be installed
near the equipment and should be easily accessible.
Choosing a Location
Place your fax machine on a flat, stable surface, such as a desk. Select a
place that is free of vibration and shocks. Locate the fax machine near a
telephone jack and a standard, grounded power outlet.
  
Avoid placing your machine in a high-traffic area. Do not place near
heaters, air conditioners, water, chemicals or refrigerators. Do not expose
the fax machine to direct sunlight, excessive heat, moisture or dust. Do not
connect your machine to electrical outlets controlled by wall switches or
automatic timers. Disruption of power can wipe out information in the
unitÕs memory. Do not connect your machine to electrical outlets on the
same circuit as large appliances or other equipment that might disrupt the
power supply. Avoid interference sources, such as speakers or the base units
of cordless phones.

Connections
Connecting the Power Cord
When you connect the power, the screen displays 01/01 00:00 FAX.
NOTICE:
1)This fax must be grounded using a three-prong plug.
2)Since the fax machine is grounded through the power outlet, you can
protect yourself from potentially hazardous electrical conditions on the
telephone network by keeping the power to your machine on when you
connect it to a telephone line. Similarly, you can protect yourself when
you want to move your machine, by disconnecting the telephone line
first, and then the power cord.
3)Lightning and power surges can damage this product! We recommend that
you use a quality surge protection device on the AC power line as well as
on the telephone line, or unplug the telephone line and electrical cords
during a lightning storm.
Connecting the Telephone Line
Connect one end of the telephone line cord to the jack labeled LINE on the
left side of the fax machine. Connect the other end to a modular wall jack.
Special Line Considerations
Roll Over Phone Lines
A roll over phone system is a group of two or more separate telephone lines
that pass incoming calls to each other if they are busy. The calls are usually
passed down or Òrolled overÓ to the next available phone line in a preset order.
Your fax machine can work in a roll over system as long as it is the last
number in the sequence, so the call cannot roll away. Do not put the
fax machine on any of the other numbers; when the other lines are busy and a
second fax call is received, the fax call is transferred to a line that does not
have a fax machine. Your fax machine will work best on a dedicated line. 
						

							7LOCATION AND  CONNECTIONS
Two-Line Phone System
A two-line phone system is nothing more than two separate phone numbers
on the same wall outlet. The two phone numbers can be on separate jacks
(RJ11) or combined into one jack (RJ14). Your machine must be plugged
into an RJ11 jack. RJ11 and RJ14 jacks may be equal in size and
appearance and both may contain four wires (black, red, green, yellow). To
test the type of jack, plug in a two-line phone and see if it can access both
lines. If it can, you must separate the line for your machine.
Converting Telephone Wall  Outlets
There are three ways to convert to an RJ11 receptacle. The first two ways
may require assistance from the telephone company. You can change the
wall outlets from one RJ14 jack to two RJ11 jacks. Or, you can have an
RJ11 wall outlet installed and slave or jump one of the phone numbers to it.
The third way is the easiest: Buy a triplex adapter. You can plug a triplex
adapter into an RJ14 outlet. It separates the wires into two separate RJ11
jacks (Line 1, Line 2) and a third RJ14 jack (Lines 1 and 2). If your Brother
machine is on Line 1, plug the machine into L1 of the triplex adapter. If
your machine is on Line 2, plug it into L2 of the triplex adapter.

							8CHAPTER TWO
Installing Brother Machine, External Two-Line TAD,
and Two-Line Telephone
When you are installing an external two-line telephone answering device
(TAD) and a two-line telephone, your machine must be isolated on one line
at both the wall jack and at the TAD. The most common connection is to put
the Brother machine on Line 2, which is our assumption in the following
steps. The back of the two-line TAD must have two telephone jacks: one
labeled L1 or L1/L2, and the other labeled L2. You will need at least three
telephone line cords, the one that came with your machine and two for your
external two-line TAD. You will need a fourth line cord if you add a two-
line telephone.
1Place the two-line TAD and two-line telephone next to your
Brother machine.
2Plug one end of the telephone line cord for your machine into the L2
jack of the triplex adapter. Plug the other end into the LINE jack on the
left side of the machine.
3Plug one end of the first telephone line cord for your TAD into the L1
jack of the triplex adapter. Plug the other end into the L1 or L1/L2 jack
of the two-line TAD.
4Plug one end of the second telephone line cord for your TAD into the
L2 jack of the two-line TAD. Plug the other end into the EXT. jack on
the left side of the machine.

Two Line External TAD Brother Machine
You can keep two-line telephones on other wall outlets as always. There are
two ways to add a two-line telephone to the fax machineÕs wall outlet. You
can plug the telephone line cord from the two-line telephone into the L1+L2
jack of the triplex adapter.  Or, you can plug the two-line telephone into the
TEL jack of the two-line TAD. 
						

							9LOCATION AND  CONNECTIONS
Multi-Line Connections (PBX)
Most offices use a central telephone system. While it is often relatively
simple to connect the fax machine to a key system or a PBX (Private Branch
Exchange), we suggest that you contact the company that installed your
telephone system and ask them to connect the fax machine for you. It is
advisable to have a separate line for the fax machine. You can then leave the
fax machine in FAX ONLY Mode to receive faxes any time of day or night.
If the fax machine is to be connected to a multi-line system, ask your
installer to connect the unit to the last line on the system. This prevents the
unit from being activated each time a telephone call is received.
   
As with all fax units, this machine must be connected to a two wire system. If
your line has more than two wires, proper connection of the fax machine
cannot be made.
If you are installing the fax machine to work with a PBX:
1It is not guaranteed that the unit will operate correctly under all
circumstances with a PBX. Any cases of difficulty should be reported
first to the company that handles your PBX.
2If all incoming calls will be answered by a switchboard operator, it is
recommended that the Answer Mode be set to MANUAL. All incoming
calls should initially be regarded as telephone calls.
3The unit may be used with either pulse or tone dialing telephone service.
Custom Features on Your Phone Line

refer to the Troubleshooting chapter, p. 52.

							10CHAPTER TWO
Connecting an External
Telephone Answering Device (TAD)
Sequence
You might choose to connect an additional answering system.  When you
have an external TAD on the same telephone line as the fax machine, the
TAD answers all calls. The fax machine ÒlistensÓ for fax calling (CNG)
tones. If it hears them, the fax machine takes over the call and receives the
fax. If it doesnÕt 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 four rings (the recommended setting is two
rings). The fax machine cannot hear CNG tones until the TAD has answered
the call, and with four rings there are only 8Ð10 seconds of CNG tones left
for the fax Òhandshake.Ó  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 4
rings.
  
Do not connect a TAD elsewhere on the same phone lineÑyour fax machine
and TAD will both try to control the line.
