from the telephone. You will have to
pull quite forcefully, but this will
not break the stand.

of the display.

from your local telephone company.

Why can’t I dial a number in the
Callers List?

You must subscribe to a Caller ID†
service for names and/or numbers
to be recorded in the Callers List. If
the number of the caller is unknown
or private, you cannot return the
call. Or, the number may require an
area code. Press the EditNum softkey
to edit the number, then press the
Dial softkey.

Why can’t I hear a caller or be
heard?

Increase the receiver or speaker
volume. Make sure the handset cord
is inserted securely into the jack. If
the speaker light is flashing, the call
is muted; press the ß key to
turn mute off; the light will be
steady and not flashing.

Why does the telephone wobble?

Make sure the cords are routed
properly through the stand, as
indicated in the Installation section.
Check that the stand has been
properly snapped into place.

What does Hold Msg do?

This is an option available with
some Call Waiting† services. When
you are on a call, and another call
comes in on Call Waiting, you can
press the Hold Msg softkey to send a
network message to the caller. The
message will ask the caller to hold,
and tell them that you will be with
them shortly. You can then answer
the call at your convenience.
Contact your local telephone
company for activation information.

What does Answ_CW or Switch
do?

This is an option available with
some Call Waiting† services. These
softkeys allow you to put the
current call on hold, and answer a
Call Waiting call. You can then
switch between calls normally.
Contact your local telephone
company for activation information.

What is a softkey?

There are three keys on both the left
and right side of the display. They
do different things, depending on
the command displayed next to
them. See the section “How do I use
softkeys?” for more information.

† These services may have different
names in your area. Contact your
telephone company for details.
