Getting started

Telephone base and charger installation

Install the telephone base and charger as shown below. If you subscribe to high-speed Internet service (DSL - digital subscriber line) 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.

The telephone base comes ready for tabletop use. If you want to mount your telephone on a wall, refer to Wall mount installation on page 7 for details.
