Troubleshooting
The telephone does
not receive caller ID or
the telephone does not
display caller ID during
call waiting.
Common cure for
electronic equipment:
If you select NEW CALL FIRST in CALL LIST
•
ORDER, the telephone first shows the new
(unreviewed) caller ID entries then entries
starting with the most recent call in the call
history. If you select BY TIME, the telephone
shows the caller ID entries starting with the
most recent call in the call history (see Feature
summary on page 15).
•
If you subscribe to high-speed Internet
service (digital subscriber line - DSL) through
your telephone line, you must install a DSL
filter between the telephone line cord and
the telephone wall jack (see Telephone
installation on page 8). The filter prevents
noise and caller ID problems caused by DSL
interference. Please contact your DSL service
provider for more information about DSL filters.
•
Make sure the area codes are set correctly in
the telephone (see Set home area code on
page 16 and Set local area code on page 16).
•
Reset the telephone. See Common cure for
electronic equipment on this page.
•
Make sure you subscribe to caller ID with call
waiting features provided by the telephone
service provider.
•
The caller might not be calling from an area
that supports caller ID.
•
Both your and the caller's telephone service
providers must use equipment compatible with
caller ID service.
If the telephone is not responding normally, try
resetting the telephone. Do the following in the
order listed:
1.
Disconnect the telephone line cord from the
telephone base.
2.
Remove the batteries.
3.
Wait a few minutes before connecting the
telephone line cord to the telephone base.
4.
Re-install the batteries.
5.
Wait for the telephone to synchronize its
connection. This might take up to one minute.
