If you subscribe to high-speed Internet service (DSL - digital
subscriber line) through your telephone line, you must install a
DSL filter between the telephone line cord and telephone wall
jack (see pages 5-6). The filter prevents noise and caller ID
problems caused by DSL interference. Please contact your DSL
service provider for more information about DSL filters.
For customer service or product information, visit our website at
www.telephones.att.com or call 1 [phone].
In Canada, dial 1 [phone].

• Communication devices such as television sets, VCRs or other
cordless telephones.
• Excessive heat sources.
• Noise sources such as a window with traffic outside, motors,
microwave ovens, refrigerators or fluorescent lighting.
• 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

NOTE: The headset base and headset do not have an external ringer. When
you receive calls, the headset earpiece plays an alert tone. If you have
telephones connected to the same telephone line as the headset base, you
can rely on the ringers of those telephones to alert you to incoming calls.

Battery installation
The battery is permanently attached to the battery compartment
cover (known as the battery pack). Do not try to separate them
from each other. After installing the battery pack, charge it for
at least 15 minutes. You may be able to make and receive short
calls. For optimal performance, charge the headset battery for
at least three hours before use. When fully charged, the headset
battery provides approximately 12 hours of talk time or five days
of standby time. When the headset is not in use, recharge by
returning it to the headset base.
NOTES:
Remove the any headset attachment (earbud excluded) before battery
replacement.

Add and register headsets
The TL7710 accommodates up to two cordless headsets. The
headset provided with your TL7710 is already registered. You
can add a new headset (TL7700, purchased separately) to the
headset base at any time. You must register a new headset
with the headset base before use (see page 13).
-OR-
You can register a maximum of two TL7710 headsets to an
AT&T DECT 6.0 telephone. The telephone base recognizes and
counts a headset the same as a handset. When you register
the TL7710 to an AT&T DECT 6.0 telephone, the headset base
acts only as a charger for the headset. You can place the
headset base anywhere you have an available power outlet. Do
not plug in the telephone line cord; you only need to plug the
headset base into a power outlet (see page 13).
Refer to your telephone user’s manual for the maximum
number of handsets that you can register to the telephone
base. If you have the maximum number of handsets registered,
you need to follow the deregistration information in your
telephone user’s manual. Visit www.telephones.att.com
for a list of compatible cordless telephones.
You can only register the headset to one product at a time. You
must deregister the headset before registering it to a headset
base or a telephone (see pages 15-16).
