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 (page 6). 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.
CAUTION: To reduce the risk of fire or injury to persons or damage to
the telephone, read and follow these instructions carefully:
Use only alkaline AA batteries (not included).
Dispose of these batteries in a safe manner. Do not burn or puncture. Like
other batteries of this type, if burned or punctured, they could release
caustic material which could cause injury.
Do not open or mutilate the battery. Released electrolyte is corrosive and
may cause damage to the eyes or skin. It may be toxic if swallowed.
Exercise care in handling batteries in order not to create a short circuit. Do
not allow conductive materials such as rings, bracelets or keys to touch the
battery. The battery or conductor may overheat and cause harm.
Use the battery identified for use with this product only in accordance with
the instructions and limitations specified in this manual.
Observe proper polarity orientation between the battery and metallic contacts.
Do not disassemble your telephone. There are no serviceable parts inside.
Refer to qualified service personnel for servicing.

Getting started

Battery installation
Before using the telephone, you should install four new AA alkaline batteries
(not included) to provide memory backup and enable the use of some
features. The four AA batteries are required for the following features to work:
speakerphone, mute, flash, caller ID, display, menu, directory, redial, speed
dial, clock, Audio Assist®and the INCOMING CALL light.
If you unplug the telephone line cord from the telephone wall jack when there
are no working batteries installed, the following information will be lost: caller
ID history, directory entries, speed dial entries, and all settings in the feature
menu. We recommend you install new batteries before initial use and change
the batteries soon after the low battery icon appears.
CAUTION: Always unplug the telephone line cord before installing new batteries.
Detach the battery compartment cover from the telephone base.2.

prevent possible leakage.
After replacing the batteries, you need to reset the date and time. For instructions, see Set
date and time on page 11.
