Installation - AT&T CL4940 User Manual

Getting started

Installation

You must install the
power adapter 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 (see pages 6-9).
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 page 4). 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.
