About Caller Identification (Caller ID)
This product has a Caller ID with CallWaiting feature that works with
service available from your local phone service provider.
Caller ID with CallWaiting lets you see who’s calling before you answer the
phone,even when you’re on another call.
You may need to change your phone service to use this feature. Contact
your phone service provider if:
• You have both Caller ID and CallWaiting,but as separate services
(you may need combined service)
• You have only Caller ID service,or only CallWaiting service
• You don’t subscribe to any Caller ID or CallWaiting services.
You can also use this product with regular Caller ID service,or with no
Caller ID services.
There are fees for Caller ID services,and they may not be available in all
areas.
Depending on your service,you may see the caller’s number,or the caller’s
name and number. This product can provide information only if both you
and the caller are in areas offering Caller ID service,and if both telephone
companies use compatible equipment. The time and date are sent by the
service provider along with the call information.
About Home Area Code and Local Area Codes
Always program your home area code,and,if you need them,up to four
local area codes (see“Set HomeArea Code”and“Set LocalArea Codes”on
pages 9 and 10). Programming these area codes will change how numbers
are displayed in the Call History,and will allow for correct operation of the
Display Dial feature.

About Caller Identification
When the first call is received,the unit sets the current time and date
automatically (you cannot set them),and resets them each time a new call
comes in. (The time and date line remain blank until the first call comes
in.) The unit automatically adjusts for daylight savings time. When not in
use,the unit displays the current date/time,number of new calls received
since the last review of memory,and number of reviewed calls in Call
History (up to 99).
For each call that comes in,the screen displays the following information
between the first and second rings:
• Your caller’s name (15 letters are sent by your telephone
company);
• The caller’s area code and telephone number (the area code is
not displayed if it is programmed as the HomeArea Code);
• The time and date of the call;and
• The position of the call in Call History.
If you answer a call before the information appears on the screen,it will
not be in the Call History.

For Customer Service,visit our website at www.telephones.att.com or call
1 800 222–3111. Please retain your receipt as your proof of purchase.
No Dial Tone
• Make sure all plugs are connected properly. Inspect the line cord
connections at the modular jack and at the telephone. Also inspect the
coiled handset cord connections at both ends.
• Unplug the telephone and connect it to another modular jack. If it still
does not work,and other telephones in your home are working,the
problem is with this telephone.

SETTINGS). If you have dial pulse service,you cannot dial numbers
with the phone set to touch tone dialing.
• If you have just used theTemporaryTone feature,leave the handset on

Telephone Does Not Ring
• Make sure the RINGERVOLUME switch is not set to OFF.

telephones connected can also create problems such as low ringer
volume or impaired sound quality during calls.
Difficulty Storing Numbers in Memory
• Make sure you are pressing the correct sequence of buttons for storing
numbers.
• If you are interrupted by a recorded announcement telling you to hang
up or by a loud buzzing noise,hang up and try to enter the number
more quickly.

ended,press G,R,M,and a memory location.
• If someone lifts an extension phone while you are storing numbers in
memory,programming might be interrupted. Make sure all extensions
are on hook while storing numbers in memory.
