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 over a long period of time, even

when not in use.

• If you leave the battery pack in the handset without charging it, the battery

pack will be completely discharged.
It may require several times of charging to recover 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. However, do not leave 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 even after

12 hours

of charging,

the usable life of the battery has expired and needs replacement.
Contact your local Sony authorized dealer or service center, and ask
for a Sony

BP-T23

rechargeable battery pack.

Note

Battery life may vary depending on usage condition and ambient temperature.

spare battery pack.

lid of the base phone.

Insert the battery pack (with
contacts facing down) into the
battery compartment.

Close the battery compartment
lid.

The SPARE BATTERY lamp
lights up. Charge the battery
pack for more than 24 hours so
that the battery is fully charged.
The SPARE BATTERY lamp
remains lit even after charging
is completed.

Entering the area code

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 live 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
advantage of this system. See “To enter the local area code (For 10 digits phone number users)”
on page 18.

Case

local calls in your area, at
