Troubleshooting

Home area code on page 17).
• 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 base
and charger installation on page 6). The filter prevents noise and caller
ID problems caused by DSL interference. Please contact your DSL service
provider for more information about DSL filters.
