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.
. 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.
. Plug one end of the telephone line cord into the TEL LINE jack on the back
of the telephone base. Plug the other end of the telephone line cord into a
telephone wall jack.
3. Plug the small end of the power adapter into the POWER jack on the back
of the telephone base. Plug the large end into a standard electrical outlet
