Getting started

Installation preparation

You must install the power adapter before using the telephone.

See pages 6-7 for easy instructions.

If you subscribe to high speed Internet service (DSL - digital subscriber line) through your telephone line, you must install a DSL filter between each telephone line cord and telephone wall jack (pages 6 and 7). 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 telephone base display - remove it before use.
