Introduction
About Your New VideoPhone
The AT&T VideoPhone 2500
allows you to enjoy a wide variety of
telephone features. When you call
someone who has a VideoPhone
compatible with the Global
VideoPhone Standard” (9), you
can see and hear each other.
During video calls, images are dis-
played in motion on a high-quality,
color video screen as you talk. For
privacy, you can close the shutter
on the camera at any time so your
image cannot be received by
another VideoPhone.
The camera lens provides a field of
view wide enough to include several
people in the viewing image. To make
group conversations more enjoyable,
an enhanced speakerphone design
makes speech sound clearer and
more natural than ever before.
Because the VideoPhone provides
many advanced features not found
on standard telephones, we recom-
mend that you read this manual care-
fully. It explains everything you need
to know to get the most pleasing
results from your new VideoPhone.
If you have any questions, call the
AT&T National Service Center at
1 800 437-9504. The call is toll free,
and we'll be glad to help.
Parts Checklist
Remember to save your sales receipt
in case you ever need warranty
service. Check to make sure the tele-
phone package includes the following

Memory Features
Each stored number remains in
memory unless you erase it or
change it by entering another number
in the same memory location. If you
replace the battery at least once a
year, the memory will be retained
even during a prolonged loss of
electrical power. ,
Capacity: The telephone can store
12 telephone numbers, each up to 16
digits long. Each character counts as
one digit, whether it is a number, a
hyphen, or a special command such
as Pause or Wait (see page 18).
One-touch dialing: The 12 spaces
on the directory card are one-touch
memory locations (Figure 1). You can
dial any telephone number stored in
memory simply by pressing the but-
ton next to the number.
Directory card: Remove one of the .
directory cards as shown. Write your
telephone number in the space pro-
vided on the bottom of the card. Also
write in the telephone numbers (or
names) that you want to store in each
memory location. Then replace the
card and plastic cover as shown
(Figure 2).
