Getting started

Before you install

To use this product as a two-line telephone, you must have a two-line modular
wall jack or two separate one-line modular wall jacks. To use both lines of a
two-line telephone, your local telephone company must provide two telephone
numbers.

This product is designed to operate optimally with two telephone lines. If
you choose to install only one telephone line, the telephone will continue to
operate normally as long as the unused line is not selected. For example, if you
press LINE 2 when there is only one line installed and that line is connected to
the L1 or L1/L2 jack, the telephone does not function properly. Simply press
LINE 1 and begin again.

Choose a central location close to a telephone jack. The telephone base can be
placed on a flat surface or mounted on a standard wall plate.

Avoid placing the telephone base too close to:

• Excessive heat sources.

• Excessive dust sources such as a workshop or garage.

• Excessive moisture.

• Extremely low temperature.

• Mechanical vibration or shock such as on top of the washing machine or
work bench.

Troubleshooting

If you have difficulty with your telephone, please try the suggestions below.
For Customer Service, visit our website at www.telephones.att.com or
call 1 [phone]. In Canada, dial 1 [phone].

My telephone
does not work
at all.

There is no dial
tone.

The telephone
does not ring
when there is an
incoming call.

• Make sure the telephone line cord is plugged firmly into the
telephone base and the modular wall jack.

• Disconnect the telephone base from the modular jack and
plug in a working telephone. If this telephone does not
work, the problem is probably in the wiring or the local
service. Call the local telephone company.

• First, try all the above suggestions.

• Make sure a line is selected and that the selected line
is connected to the telephone line on the back of the
telephone base. If you installed this telephone with only one
telephone line, make sure the connected line is selected.

• Make sure hold is not activated.

• The telephone line cord might be malfunctioning. Try
installing a new telephone line cord.

• Disconnect the telephone base from the telephone jack and
connect a different telephone. If there is no dial tone on
that telephone either, the problem is in your wiring or local
service. Contact your local telephone company.

• Make sure the ringer is on (page 12).

• Make sure the telephone line cord is plugged in properly
(pages 6-7).

• There may be too many extension telephones on the
telephone line to allow all of them to ring simultaneously.
Try unplugging some of them.

• If the other telephones in your home are having the same
problem, the problem is in the wiring or local service.
Contact the local telephone company (charges may apply).

• Other electronic products can cause interference to your
telephone.

22

Appendix

Troubleshooting

• Test a working telephone at the same telephone jack. If
another telephone has the same problem, the problem
is in the telephone jack. Contact your local telephone
company (charges may apply).

• The telephone line cord might be malfunctioning. Try
installing a new telephone line cord.

I cannot dial out. • First, try all the above suggestions.

• Make sure there is a dial tone before dialing.

• Make sure the telephone is set to the correct dial mode
(pulse dial or tone dial) for the service in your area.
Refer to the Base settings section of this user’s manual
(page 11) to set the dial mode.

• If the other telephones in your home are having the
same problem, the problem is in the wiring or local
service. Contact your local telephone company (charges
may apply).

• Eliminate any background noise. Noise from a television,
radio, or other appliances may cause the telephone
to not dial out properly. If you cannot eliminate the
background noise, first try muting the telephone before
dialing, or dialing from another room in your home with
less background noise.

My calls fade out
when I am using
the telephone.

• Other electronic products can cause interference to your
telephone.

• If your telephone is plugged in with a modem or a surge
protector, plug the telephone (or modem/surge protector)
into a different location. If this doesn't solve the problem,
re-locate your telephone or modem farther apart from each
other, or use a different surge protector.

• If the other telephones in your home are having the
same problem, the problem is in the wiring or local
service. Contact your local telephone company (charges
may apply).

Troubleshooting

I hear other
calls when using
the telephone.

Automatic redial
interrupted.

Speakerphone
does not
work while
an extension
telephone is in
use.

• Disconnect the telephone base from the telephone jack.
Plug in a different telephone. If you still hear other calls,
the problem is probably in the wiring or local service.
Call your local telephone company.

• If the telephone rings during the automatic redial
sequence, you will cancel it if you lift the handset,
press SPEAKER or press HEADSET (if a headset is
connected) to take the call.

• Lifting the handset, pressing SPEAKER or pressing
HEADSET (if a headset is connected) will cancel
automatic redial.

• Low battery power can affect automatic redial. For
information about changing batteries, see Battery
installation on page 5.

• The speakerphone is powered by the current in the
telephone line cord connected to your wall jack. The
speakerphone might not work if you are on a call on
a line-powered extension telephone and try to use the
983 speakerphone at the same time. There may not be
enough power in the line current to support both the
speakerphone and the extension telephone. Try using the
handset for calls like this.

Telephone does
not work with
headset.

Warning tone
sounds when lift
the handset or
press SPEAKER.

• Make sure four new AA alkaline batteries are properly
installed (see Battery installation on page 5).

• Use only an industry standard two-band 2.5 mm head­set (purchased separately). For best results, use an AT&T
two-band 2.5 mm headset.

• Make sure four new AA alkaline batteries are properly
installed (see Battery installation on page 5).

FCC and ACTA information

If this equipment was approved for connection to the telephone net­work prior to July 23, 2001, it complies with Part 68 of the Federal
Communications Commission (FCC) rules. If the equipment was approved
after that date, it complies with the Part 68 rules and with Technical
Requirements for Connection of Equipment to the Telephone Network
adopted by the Administrative Council for Terminal Attachments (ACTA).
We are required to provide you with the following information.

1. Product identifier and REN information

The label on the back or bottom of this equipment contains, among
other things, an identifier indicating product approval and the Ringer
Equivalence Number (REN). This information must be provided to your
local telephone company upon request. For equipment approved prior
to July 23, 2001, the product identifier is preceded by the phrase “FCC
Reg No.” and the REN is listed separately. For equipment approved after
that date, the product identifier is preceded by “US” and a colon (:), and
the REN is encoded in the product identifier without a decimal point as
the sixth and seventh characters following the colon. For example, the
product identifier US:AAAEQ03T123XYZ would indicate an REN of 0.3.

The REN is used to determine how many devices you may connect to your
telephone line and still have them ring when you are called. In most, but
not all areas, the sum of all RENS should be five (5.0) or less. You may
want to contact your local telephone company for more information.

2. Connection and use with the nationwide telephone network

The plug and jack used to connect this equipment to the premises wiring
and the telephone network must comply with the applicable part 68 rules
and technical requirements adopted by ACTA. A compliant telephone cord
and modular plug is provided with this product. It is designed to be con­nected to a compatible modular jack that is also compliant. An RJ11 jack
should normally be used for connecting to a single line and an RJ14 jack
for two lines, see installation instructions in the user’s manual. This equip­ment may not be used with coin telephone lines or with party lines. If you
have specially wired alarm dialing equipment connected to your telephone
line, ensure the connection of this equipment does not disable your alarm
equipment. If you have questions about what will disable the alarm equip­ment, consult your telephone company or qualified installer.

given the opportunity to correct the problem and the telephone company
is required to inform you of your right to file a complaint with the FCC. Your
telephone company may make changes in its facilities, equipment, operation,
or procedures that could affect the proper functioning of this product. The
telephone company is required to notify you if such changes are planned.

5. Hearing aid compatibility

If this product is equipped with a corded or cordless handset, it is hearing aid
compatible.

6. Programming/testing of emergency numbers

card (if applicable), so that you can still dial the emergency number
manually if the memory dialing feature doesn’t work.

b. This feature is provided only as a convenience, and the manufacturer

assumes no responsibility for customer reliance upon the memory feature.

c. Testing the emergency telephone numbers you have stored is not recom-

mended. However, if you do make a call to an emergency number:

• You must remain on the line and briefly explain the reason for the call

before hanging up.
