Before you begin
About Caller Identification
Caller ID with Call Waiting features in
this telephone let you see who’s calling
before you answer the phone, even
when you’re on another call. These
features require services provided by
your local telephone company.
Contact your telephone service
provider if:
• You have both Caller ID and Call
Waiting, but as separate services
(you may need combined service);
• You have only Caller ID service, or
only Call Waiting service;
• You don’t subscribe to any Caller
ID or Call Waiting services.
You can use this phone with regular
Caller ID service, and you can use its
other features without subscribing to
either Caller ID or combined Caller ID
with Call Waiting service. There may
be fees for these services, and they
may not be available in all areas.
Caller ID features will work only if
both you and the caller are in areas
offering Caller ID service, and if both
telephone companies use compatible
equipment.
See Caller ID Operation, beginning on
page 22, for more details about how
these features work.
Telephone operating range
This cordless telephone operates with
the maximum power allowed by the
Federal Communications Commission
(FCC). Even so, this handset and base
can communicate over only a certain
distance — which can vary with the
locations of the base and handset, the
weather, and the construction of your
home or office. For best performance,
keep the base antenna fully upright.
If you receive a call while you are
out of range, the handset might not
ring — or if it does ring, the call might
not connect when you press PHONE.
Move closer to the base, then press
PHONE to answer the call.
If you move out of range during a
phone conversation, you might hear
noise or interference. To improve
reception, move closer to the base.
If you move out of range without
pressing OFF, your phone will be left
“off the hook.” To hang up properly,
walk back toward the telephone base,
periodically pressing OFF until the call
is disconnected.

Caller ID Logs
Caller ID Logs
How Caller ID works
If you subscribe to Caller ID service provided by your
local phone company, information about each caller will
be displayed after the first ring.
Your call log holds up to 50 entries. Each entry can contain a number up to 16 digits, and a name up to 16 letters long. You can review the call log to find out who
has called, return the call without dialing, or copy the
caller’s name and number into your phonebook.
Each log entry is numbered (number 01 is always the
most recent). When the call log is full, the oldest entry is
deleted to make room for new incoming call information.
If you answer a call before the information appears on
the screen, it will not be saved in your call log.
About names
If the telephone number of the person calling matches a
number in your phonebook, the name that appears on
screen will match the name as you entered it into your
phonebook. (Example: If “Christine Smith” calls, her
name will appear as “Chris” if this is how you entered it
into your phonebook.)

Adding new handsets
Your telephone can accommodate up to eight cordless handsets . You can add new
handsets (Model E250, sold separately) at any time, but each must be registered with the
base before use.
Before using a new handset, you must register it with the
base. During registration, you must enter the 15-digit ID
number of the telephone base. The Base ID is located on
the bottom of the base unit.
Follow the instructions provided with your new handset
to register it for use with your telephone.
The handset provided with your telephone is automatically
registered as Handset 1. Additional handsets will be
assigned numbers in the order they are registered (2, 3, 4,
etc.) up to a maximum of eight .

Charging spare batteries
Optional spare batteries (sold separately) can be kept charged in the base, for quick
replacement when handset batteries become depleted. For best results, use AT&T AA
rechargeable batteries (SKU 26820).
In the event of a power failure, the charged batteries in the base will allow you to
make and receive calls from the cordless handset for up to 2.5 hours.
Spare batteries require at least 24 hours to reach full charge.
Slide latch left to open battery drawer.
Insert spare batteries,
then close drawer.
Caution: Use only the supplied NiCd
battery (80-5469-00-00) or AT&T model
2AA NiMH replacement battery (SKU
26820). Do not use alkaline batteries.

In case of difficulty
If you have difficulty with your phone, please try the suggestions below. For Customer
Service, visit our web site at www.telephones.att.com, or call 1–800–222–3111.
Telephone does
not work at all
• Make sure batteries are installed and charged correctly (see page 7).
• Make sure the AC adapter is plugged into an outlet not controlled by a
wall switch.
• Make sure the telephone line cord is plugged firmly into the base unit
and the modular jack.
• Make sure the base antenna is fully upright.
• If these suggestions do not work, unplug the base, remove and re-insert
the batteries, then place the handset in the base to re-initialize.
Phone does not
ring
• Make sure the ringer is on (see pages 14).
• Make sure the telephone line cord and AC adapter are plugged in properly (see page 6).
• Make sure the base antenna is fully upright.
• Move the handset closer to the base.
• You might have too many extension phones on your telephone line to
allow all of them to ring. Try unplugging some of them.
If you hear noise
or interference
during a call
• Make sure the base antenna is fully upright.
• You may be out of range. Move closer to the base.
• Appliances plugged into the same circuit as the base can cause
interference. Try moving the appliance or base to another outlet.
• The layout of your home or office might be limiting the operating range.
Try moving the base to another location, preferably on an upper floor.
• If the buttons don’t work, try placing the handset in the base for at least
15 seconds.
• Disconnect the base from the modular jack and plug in a corded telephone. If calls are still not clear, the problem is probably in your wiring
or local service. Call your local telephone service company.
• Non-rechargeable batteries have been installed. They must be removed
immediately and replaced with rechargeable NiMH batteries (see
page7).
• Rechargeable batteries have been installed but may be old or need to
be replaced. Remove and re-install the batteries and use normally until
fully discharged then let them fully recharge in the handset or base.
• If the above measures do not correct the problem, your batteries should
be replaced (see page 7).
"Warning! Use
Rechargeable
Batteries Only" is
displayed on
screen
• You were probably out of range. Move closer to the base. Before
placing another call, set the handset in the base for at least 15
seconds.
If you lose a call

handset
