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
items shown below:

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 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).

video module) so that a blank, light-
colored wall is behind you as you
speak. Avoid brightly painted walls
and bold wallpaper patterns that
could be distracting. Never place the
phone so that reflective surfaces
(such as a mirror or window) are
behind you.
Lighting: Choose a room with bright,
evenly distributed tight. Adjust lighting
(or swivel the video module) so that
a soft, glare-free light source, for
example, a table lamp, illuminates
your face when you make video cails
(Figure 2). Never point the camera
directly toward a window or other
bright light source.
Figure 2
Sitting position: Position the
VideoPhone so that you have room
to sit comfortably between one and
five feet from the camera. The best
picture is transmitted to the other
VideoPhone when your face is
about an arm’s length from the
screen (Figure 2).

Camera range: People and objects
from one to nine feet away from the
camera should appear in acceptable
focus. To include several people in
the scene, move back five to seven -
feet from the telephone for a wider
field of view.
Image motion: Avoid excessive
motion during video calls. Because
the video signal is transmitted as a
series of images, you may notice a
slight delay under certain circum-
stances, so that a person’s lips are
slightly out of synchronization with

To assure privacy when you don’t
want to be seen by VideoPhone
callers, move the shutter switch
on top of the video module to the
closed position.
When the shutter is closed, the cam-
era lens is physically blocked. This
prevents your video image from being
transmitted, so you cannot be seen
even if the VIDEO button is pressed
accidentally (you will still be able to
see the person you are talking to).
The shutter can be opened or closed
at any time, either before or during
a call. Be sure to open the shutter

command (such as x70) to temporarily
disable call waiting before placing a
call. You may want to insert this com-
mand into the VideoPhone numbers
you store in memory, so that Call
Waiting is turned off each time you
make a video call (see page 19).
Remember that only the calling party
can disable Call Waiting. The video
signal could still be disrupted if the
person you call receives a Call ~
Waiting signal.
Even if Call Waiting is active, you
may not hear Call Waiting signals
during video calls. You will hear
Call Waiting signals during normal
telephone calls.

In Case Of Difficulty
If your VideoPhone does not work
properly, try the following suggestions
before seeking repair assistance.
No Dial Tone
«= Make sure the red HOLD light is
not on.
«= Viake sure all plugs are connected
properly.
Inspect the line cord connections at
the modular jack and at the tele-
phone. Also inspect the coiled hand-
set cord connections at both ends.
te Unplug the telephone and connect
it to another modular jack. If it still
does not work, and other tele-
phones in your home are working,
the VideoPhone may need repair.
Call the AT&T National Service
Center at 1 800 437-9504.
Call Cannot Be Dialed, Or is Dialed
Slowly ‘
See page 10 to reset the DIAL MODE
switch. If you have pulse dialing ser-
vice, you cannot dial numbers with
the switch set to TONE (touch tone).
Set the switch to PULSE (dial pulse),
then hang up and dial again.
If you have tone dialing service, you
can use either tone or pulse dialing
mode. If you set the switch to TONE,
numbers are dialed much more
quickly.
Difficulty Entering Numbers Into
Memory
r= Review page 18 to make sure you
are following the correct procedure.
«= If you receive a message because
the number is too long, try the sug-
gestions on page 20 for entering
long numbers into memory.
28
«= Programming is not possible
during a power failure. . Fi
«= Check the AC adapter and power,
cord to the phone to make sure
both are securely connected (see
page 11).
«= Safety circuits inhibit certain func-
tions when the phone becomes too
warm (see “Overheating” on page
30). Wait 30: minutes for the phone
to cool, then try again.
Low Battery Warning
When the phone beeps and the
“LOW BATTERY” message appears,
the battery should be replaced within
two weeks to protect memory in case
of power loss (see page 10).
Telephone Does Not Ring
t= Lift the handset; if the message
“RINGER OFF” appears, reset the
ringer switch at the back of the
phone to LOW or HI.
«x [f there are several other telephones
on the same line, try disconnecting
some of the other telephones.
Having too many telephones con-
nected can also cause problems
such as low ringer volume or
impaired sound quality during calls.
Speakerphone Does Not Work
«= Make sure the red MUTE light is
not on.
«= The speakerphone may be turned
off if someone picks up the hand-
set of an extension telephone on
the same line. Speakerphone
operation will resume if the
handset of the other telephone
is replaced.
In Case Of Difficulty (continued) —
c= Speakerphones will not work
properly in a very noisy room.
«= If electrical power is lost, you will
have to lift the handset first, then
switch to the speakerphone.
Brief Silence During a Regular Call
«= |f your videophone is used near a
FAX machine, at times you may
not be able to hear or be heard on
a regular call. The modem tones
from a FAX machine may falsely
trigger the VideoPhone modem,
creating a brief period of silence
(see “VideoPhone Location” on
page 9).
Blank Video Screen. .
Press to make sure your
video module is working. If the screen
remains blank after a minute, check
the following:
«= Make sure the camera shutter on
_ top of the video module is in the
OPEN position (see page 26).
m= Check the AC adapter and its
cords to make sure all are securely
connected. Make sure the electri-
cal outlet is working properly.
Video Call Was Not Completed
If the video screen displays your
image when you press but
you cannot receive video images
from your caller:
t= Make sure the other person is
using a VideoPhone compatible
with the Global VideoPhone
Standard (9.
t= Make sure that your caller has
pressed the button.
«= lf you still cannot establish'a video
call, the problem may be in the other
person’s phone. Ask your caller to
try the suggestions in the above
section (“Blank Video Screen’).
« Try taking turns pressing
first.
te Line noise can disrupt or prevent
video transmission. Hang up and »
try your call again.
Poor Video Image Quality
«= |f the display is too dark and the
VideoPhone has been in a cold
area, it may require approximately
30 minutes to become warm
enough to work well.
«= Adjust brightness as required to
improve picture quality (see page 25).
«= |f there are blocks of solid color on
the display, pressing may
improve the image.
ee Adjust focus as required to improve
picture sharpness and smoothness
of motion (see page 25).
«= For maximum smoothness of
motion without sound, use Silent
Video Mode (see page 26).
« If screen motion still appears unna-
turally abrupt, the problem could be
caused by excessive motion within
the camera’s field of view; this
slows the rate of images transmit-
ted. If the same problem occurs
when the person displayed on
screen is sitting still, there may be a
low level of noise on the line. If the
problem persists, hang up and call
again to get a better connection.

In Case Of Difficulty (continued)
Loss of Video Image
Video signals are transferred using a
_ high-speed modem that is sensitive
to interruptions such as tones and
power fluctuations on the line. If the
image is lost during a video call, both
you and the other person must press
to restore the picture on both
screens. Loss of the video image is
most often caused by the following:
ss The button has been
pressed by either:person. The
flash button generates a signal
that terminates video transmission.
«= An-extension telephone handset
has been lifted by someone at
_ either location. You cannot use an
_ extension telephone during a video
call. When the handset. is lifted, it
causesa slight line disruption that
can terminate video transmission.
«= A Call Waiting signal has been
‘received by either person. Call wait-
ing signals can disrupt or terminate
-“a video transmission. If you sub-
“scribe to call waiting service, you
may want to disable it before estab-
lishing a video call (see,page 27).
«= Video. transmission may be inter-
rupted if the phone becomes too
warm (see “Overheating” below).
Video transmission will resume
~. when the phone cools, usually
within 30 minutes. ©
«= Excessive telephone line noise
may cause loss of the video
image. If the problem occurs
repeatedly, hang up and call
. again to get a better connection,
30
«= Momentary loss or fluctuation of
electrical power.may also termi-
nate the video transmission. Power
often fluctuates during thunder:
_ Storms, or during periods of high
_ power demand at peak usage |
times. (These Occur most often in
the early evening hours, and during
very hot summer days.) Try your
call again later at a time when elec-
trical. power may be more stable.
Overheating
A safety circuit prevents overheating by
switching off certain functions (memory
programming and video transmission) if
the phone becomes too warm.
All functions will be restored to nor-
mal when the phone cools, usually
within 30 minutes. It is not necessary
to unplug the phone during this time.
Overheating can be prevented by:
Making sure vents on the-top and
sides of the phone are not covered |
and that.there is adequate airflow
around the phone.
1s Making sure the phone is placed
on a hard surface.
Overheating may result if the
VideoPhone is left for a period of
time on a soft surface, such as car-
peting or a bed.
«= Moving the phone if itis exposed _
to direct sunlight or installed in a
room where the temperature could
exceed 100° F.
