Installation
Install the telephone base close to a telephone jack and a power outlet not
controlled by a wall switch. For optimum range and better reception, place
the telephone base in a central and open location.
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 the following page). The
filter prevents noise and caller ID problems caused by DSL interference.
Please contact your DSL service provider for more information about DSL
filters.
Your product may be shipped with a protective sticker covering the handset or
telephone base display - remove it before use.
