Installation
You must install and
charge the battery before
using the headset.
Colored labels
The cords have colored labels that guide you to plug them into
the correct headset base jacks. The back of the headset base
has color-coded dots and the names of the jacks above them
that correspond to the colored labels on the cords.
Digital subscriber line (DSL)
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 telephone wall
jack (see pages 14 and 22). The filter prevents noise and caller
ID problems caused by DSL interference. Please contact your DSL
service provider for more information about DSL filters.

Getting started
Headset base and handset lifter installation
Option 1: Connect the handset lifter to a corded phone
The handset lifter (lifter) works with the cordless headset to
provide a complete communication solution for most corded
telephones. The lifter raises and lowers its switch hook presser to
answer, make and end phone calls. The ring detector provides an
incoming call indication through the cordless headset, so you can
answer calls even when you are away from the telephone base.
With this installation, you must set the CORDED HANDSET
CONNECTED switch to YES (see page 13). Adjust the corded
handset audio (see page 15) before you install the handset lifter
to the corded phone. See page 16 to attach the handset lifter.
