telephone line cord and the telephone wall jack. The filter prevents noise and
caller ID problems caused by DSL interference. Please contact your DSL service
provider for more information about DSL filters.
Follow the steps below to install the telephone:
Telephone installation
Plug one end of the coiled handset cord into the handset jack on the left
side of the telephone base. Plug the other end into the handset and hang up.

NOTES:
Use only the power adapter provided with this product. To obtain a
replacement, visit our website at www.telephones.att.com or call
1 [phone]. In Canada, dial 1 [phone].
The power adapter is intended to be correctly oriented in a vertical or floor
mount position. The prongs are not designed to hold the plug in place if it
is plugged into a ceiling, under-the-table or cabinet outlet.
You can use this telephone without the power adapter installed. In this
case, you can only make or answer calls with the handset, or adjust the
ringer volume or handset listening volume. For optimal performance, power
your telephone with the supplied power adapter.

call, even when you are on another call.

Answering system
About the answering system and voicemail
You may have two different types of voice messages: those left on your
built-in answering system and those left on your service provider’s voicemail
system (fees may apply). Your telephone’s built-in answering system messages
and voicemail messages are separate.
To listen to your voicemail, you typically dial an access number provided by
your telephone service provider, followed by a security code or PIN. Some
service providers bundle or combine multiple services like voicemail and call
waiting, so you may not be aware that you have voicemail. To check what
services you have and how to access them, contact your telephone service
provider.
To use your voicemail service rather than your answering system, turn off
your answering system. To use your answering system rather than your
voicemail service, contact your telephone service provider to deactivate your
voicemail service. You can also use your telephone answering system and
voicemail together by setting your built-in answering system to answer before
voicemail answers. To learn how to program your voicemail settings, contact
your telephone service provider. Then, if you are on a call, or if the answering
system is busy recording a message and you receive another call, the second
caller can leave a voicemail message.
If you have voicemail provided by your telephone service provider, we
recommend setting your answering system to answer calls at least two rings
earlier than your voicemail is set to answer. For example, if your voicemail
answers after six rings, set your answering system to answer after four rings.
Some voicemail providers may program the delay before answering calls
in seconds instead of rings. In this case, allow six seconds per ring when
determining the appropriate setting.
Message capacity
The answering system can record up to 99 messages, depending on the
length of each message. Individual messages can be up to three minutes
long, and the total maximum recording time is 19 minutes. Messages remain
available for replay until you delete them.
If the recording memory is full, the message window displays F. Delete some
messages to make room for more.

16
Answering system
Turn the answering system on or off
Press /ANS ON/OFF repeatedly to turn the
answering system on or off.
Record your outgoing announcement
The outgoing announcement is the message callers hear when calls are
answered by the answering system.
If the answering system is on, the telephone
automatically answers calls with “Hello, please leave a
message after the tone.“ You can use this announcement,
or replace it with a recording of your own.
Use the following steps to record an outgoing
announcement with a recording of your own.
Press SKIP/ANNC. The screen shows
REC PLAY and REC flashes.
Press SELECT. The screen shows USE STOP TO
END and you hear a long beep.
Speak towards the microphone (MIC) on the
telephone and maintain a distance of about
nine inches. You can record an announcement of up to two minutes.
Announcements shorter than one second are not recorded.
Press PLAY/STOP to end the recording. The recorded announcement
automatically plays back, then the telephone automatically returns to idle
mode and you hear a beep.
To play or delete the outgoing announcement
Press SKIP/ANNC. The screen shows REC PLAY DEL and REC flashes.
Press REPEAT/MEMO or SKIP/ANNC to scroll until PLAY or DEL flashes.
Press SELECT to play the current announcement. To delete the
announcement, press SELECT when DEL is flashing or press /DELETE

change the setting, follow the steps below:
Press MENU repeatedly until the screen shows # OF RINGS.
Press DIR/or CID/to select 2, 3, 4*, 5, 6, 7, tS 2-4, or tS 4-6.
If you choose tS 2-4 (or tS 4-6), the answering system answers after two
(or four) rings when there are new messages. When there are no new
messages, the answering system answers after four (or six) rings. When
you are retrieving messages from a long distance call, it disconnects
your call after three (or five) rings to avoid long distance charges. (These
tS settings are also known as toll saver.)
Press SELECT or MENU to save your selection and automatically move to
the next option. The telephone automatically returns to standby after 30
