CAUTION: •Should you experience intermittent loss of audio during a conversation, try
moving closer to the base or move base phone away from other noise sources.
•The cordless telephone operates at a frequency that may cause interference to
nearby TVs and VCRs; the base phone should not be placed near or on the top
of a TV or VCR; and, if interference is experienced, moving the cordless
telephone farther away from the TV or VCR will often reduce or eliminate the
interference.
Setting up the base phone
Do the following steps:
• Choose the best location
• Connect the base phone
• Choose the dialing mode

Notes
• Use only the supplied AC-T128 AC power adaptor.
Do not use any other AC power adaptor.
• Connect the AC power adaptor to a continuous power
supply.
• Place the base phone close to the AC outlet so that
you can unplug the AC power adaptor easily.
Tips
• If your telephone outlet is not modular, contact your
telephone ser ice company for assistance.
• L1 is the first phone line connected to center pair of
wires. L2 is the second phone line connected to outer
pair of wires.
Connecting a computer or FAX
You can connect a computer or FAX, etc. to the
DATA jack.
Notes
• L2 jack is used for recei ing or sending
computer or FAX data in addition to making
or recei ing calls.
If a call comes in on L2 jack with the “call waiting” ser ice while a
computer or FAX connected to the DATA jack is recei ing or sending
data, that data may be effected.
If you ha e data communication frequently, we recommend that you
and your callers use L2 jack for data communication only.
• If you ha e only single outlet ha ing one line, connect the telephone
line cord to the L2 jack.

Preparing the battery pack
Charge the battery pack for more than 12 hours before you start using
your phone.
1Slide open the battery
compartment lid of the handset.
2Insert the battery pack (with
contacts facing down) into the
battery compartment.
3Close the battery compartment
lid.
4Place the handset on the base
phone.
You can place it with either side
facing up.
The CHARGE lamp lights up
when the handset is properly
seated on the charge terminals
of the base phone. Charge the
battery pack for more than 12
hours so that the battery is fully

Battery duration
A fully charged battery pack lasts for about:
• Approx. 7 hours when you use the handset continuously
• Approx. 7 days when the handset is in standby mode.
Notes
• The battery pack will gradually discharge o er a long period of time, e en
when not in use.
• If you lea e the battery pack in the handset without charging it, the battery
pack will be completely discharged.
It may require se eral times of charging to reco er to its full capacity.
To obtain the best performance from the battery
Do not place the handset on the base phone after each call. The battery
works best if the handset is returned to the base phone after two or
three calls. Howe er, do not lea e the handset off the base phone for a
long period of time as this will completely discharge the battery pack.
When to purchase a new battery pack
If the battery lasts only a few minutes e en after 12 hours of charging,
the usable life of the battery has expired and needs replacement.
Contact your local Sony authorized dealer or ser ice center, and ask
for a Sony BP-T23 rechargeable battery pack.
Note
Battery life may ary depending on usage condition and ambient temperature.

When you use this phone for the first time, or move to an area that has a
different area code, you must enter your home area code. Otherwise, you
cannot use some functions of this phone and the Caller ID functions.
This is also necessary because the phone must be able to select an area code to
properly dial call from the Caller ID list.
Depending on your region, enter 3-digit area code as follows:
Case 1.
If 7-digit dialing (no area code) is accepted for local calls in your area, see “To enter
your home area code” below.
If you li e in an area where calls from or to other local areas can also be made by 10-digit dialing
(area code + number), you can register up to 5 local area codes with this telephone to take
ad antage of this system. See “To enter the local area code (For 10 digits phone number users)”
on page 18.
Case 2.
If 10-digit dialing (area code + number) is required for all local calls in your area, at
first, enter “000” in your home area code. See “To enter your home area code” below.
Then see “To enter the local area code (For 10 digits phone number users)” on page

Caller ID Features
Understanding the Caller ID service
Caller ID allows the caller’s phone number to be shown on the display
before the call is answered. In order to use this feature, you must first
subscribe to the Caller ID ser ice. The name of this ser ice may ary
depending on your telephone company.
To use this feature, be sure to enter your home area code (see page 17).
When you receive a call
The phone number appears on the display with the date and time* as
shown in the following example.
If your Caller ID ser ice includes the caller name ser ice, the caller’s
name also appears on the display (up to 15 letters).
* The display on the base phone
does not show the date and time.
When you answer the call, the Caller ID display changes to the
“TALK” or “SPEAKERPHONE” display.
Notes
• The caller’s phone number and/or name will not appear in the following cases:
- “OUT OF AREA”: when the call is made through a telephone company which
does not offer Caller ID ser ice (including international calls).
- “PRIVATE”: when the call is “blocked.” For pri acy reasons, many states allow
callers the option to pre ent his or her telephone data from being displayed on
the other party’s Caller ID display.
• If the call is from an office which uses multiple lines, the displayed phone number
may not match the number you use to call the extension.
Tips
• E en if the ringer of the handset is set to “RINGER OFF”, you can recei e
Caller ID data.
• If a call comes in on both line 1 and 2 simultaneously, the display will show
the data on line 1 and 2 alternately.
About the memory match function
If you recei e a call from a phone number which is stored on speed dialing
keys (see page 34) or in the Phone Directory (see page 37), the ringer sound
will change to a higher tone from the second ring.
Note
The memory match function does not work with “OUT OF AREA” or “PRIVATE”
calls; and it may not work with calls made from an office which uses multiple lines
because the number does not always match the one you stored in this phone.

compatible phone, unless you subscribe to the combined “Caller ID
with call waiting”service, you will not be able to see the name
and number of the second caller.
When a new call comes in while you are talking, you hear two short
beeps. The caller’s name and/or phone number of the new call appears
