Telephone installation

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. The filter prevents noise and caller ID problems caused by DSL interference. Please contact your DSL service provider for more information about DSL filters.

Follow the steps below to install the telephone.

1.Plug one end of the coiled handset cord into the handset jack on the left side of the telephone base. Plug the other end into the handset and hang up.
