Troubleshooting
Why are Callers not identified on the display?
Caller ID † information usually arrives between the first and second ring.
Let the telephone ring at least once before answering. Make sure you
subscribe to Caller ID
† services 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.
† These services may have different names in your area, contact your local
telephone company for details.
