Camera Shutter
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.
Whenthe shutter is closed, the cam-
era lens is physically blocked. This
prevents your video image from being
transmitted, so you cannot be seen
evenif the VIDEO button is pressed
accidentally (you will still be able to
see the person youaretalking to).
The shutter can be opened or closed
at any time, either before or during
a call. Be sure to open the shutter
when privacy is no longer required,
so the camera can operate normally.

Disable Call Waiting
If you subscribe to Call Waiting ser-
vice, you may wantto disableit
before making video calls. Cail
Waiting signals can cause disruption
or loss of picture during videocalls.
In many areas, you can dial a special
command (such as x70) to temporarily
disable call waiting before placing a
call. You may wantto insert this com-
mandinto the VideoPhone numbers
you store in memory, so that Call
Waiting is turned off each time you
makea video call (see page 19).
Rememberthat only the calling party
can disable Call Waiting. The video
signal could still be disrupted if the
person youcall receives a Call ~
Waiting signal.
Evenif Call Waiting is active, you
may not hear Call Waiting signals
during video calls. You will hear
Call Waiting signals during normal
telephonecalls.
