DECT 6.0 cordless telephone
with caller ID/call waiting

Installation

You must install and
charge the battery before
using the telephone.

Install the telephone base close to a telephone jack and a power outlet not
controlled by a wall switch. The telephone base can be placed on a flat surface
or vertically mounted on the wall. For optimum range and better reception, place
the telephone base in a central and open location.

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 (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.
