• The caller may not be calling from an area that
supports Calling Number Display. Both your and
the caller's telephone service providers must use
equipment which are compatible with Calling
Number Display service.
• Make sure your service provides Calling Number
Display information when on a call. This is sometimes
known as Calling Number Display with call waiting, or
type 2 Calling Number Display.
• Make sure you have installed four new AA batteries
properly.
• If you subscribe to high-speed Internet service (ADSL
- digital subscriber line) through your telephone line,
you must install a ADSL ilter between the telephone
line cord and the telephone wall jack. The ilter
prevents noise and Calling Number Display problems
caused by ADSL interference. Please contact your
ADSL service provider for more information about
ADSL ilters.
I subscribe to a nontraditional telephone service that
uses my computer to establish connections, and my
telephone doesn't work.
• Make sure your computer is powered on.
• Make sure your Internet connection is working
properly.
• Make sure that the software is installed and running
for your nontraditional telephone service.
