Taking care of your telephone
Your cordless telephone contains sophisticated electronic parts, so you must
treat it with care.
Avoid rough treatment.
Place the corded handset down gently.
Save the original packing materials to protect your cordless telephone if you
ever need to ship it.
Avoid water
You can damage your cordless telephone if it gets wet. Do not use the corded
handset in the rain, or handle it with wet hands. Do not install the cordless
telephone near a sink, bathtub or shower.
Electrical storms
Electrical storms can sometimes cause power surges harmful to electronic
equipment. For your own safety, take caution when using electric appliances
during storms.
Cleaning your telephone
Your cordless telephone has a durable plastic casing that should retain its
luster for many years. Clean it only with a soft cloth slightly dampened with
water or a mild soap.
Do not use excess water or cleaning solvents of any kind.

This symbol is to alert you to important operating or servicing
instructions that may appear in this user’s manual. Always follow basic
safety precautions when using this product to reduce the risk of injury,
fire, or electric shock.
Safety information
Read and understand all instructions in the user’s manual. Observe all
markings on the product.
Avoid using a telephone during a thunderstorm. There may be a slight chance
of electric shock from lightning.
Do not use the telephone to report a gas leak in the vicinity of the leak. Under
certain circumstances, a spark may be created when the adapter is plugged
into the power outlet, or when the handset is replaced in its cradle. This is a
common event associated with the closing of any electrical circuit. The user
should not plug the phone into a power outlet, and should not put a charged
handset into the cradle, if the phone is located in an environment containing
concentrations of flammable or flame-supporting gases, unless there is
adequate ventilation. A spark in such an environment could create a fire or
explosion. Such environments might include: medical use of oxygen without
adequate ventilation; industrial gases (cleaning solvents; gasoline vapors; etc.);
a leak of natural gas; etc.
Do not use this product near water, or when you are wet. For example, do
not use it in a wet basement or shower, or next to a swimming pool, bathtub,
kitchen sink, or laundry tub. Do not use liquids or aerosol sprays for cleaning.
If the product comes in contact with any liquid, unplug any line or power cord
immediately. Do not plug the product back in until it has dried thoroughly.
Install this product in a protected location where no one can trip over any line
or power cords. Protect cords from damage or abrasion.
f you cannot solve the problem, or if the product is damaged, refer to the
Limited warranty section on pages 19-21. Do not open this product except
as directed in your user’s manual. Opening the product or reassembling it
incorrectly may expose you to hazardous voltages or other risks.
Replace backup battery only as described in your user’s manual (see pages 6-7).
Do not burn or puncture batteries — they contain caustic chemicals.
This power adapter is intended to be correctly oriented in a vertical or floor
mount position. The prongs are not designed to hold the plug in place if it is
plugged into a ceiling, an under-the-table or cabinet outlet.
Caution: Use only the power adapter provided with this product. To obtain a
replacement, visit our website at
www.telephones.att.com or call
1 [phone]. In Canada, dial 1 [phone].

Important safety information

Especially about cordless telephones
Privacy: The same features that make a cordless telephone convenient
create some limitations. Telephone calls are transmitted between the
telephone base and the handset by radio waves, so there is a possibility that
your cordless telephone conversations could be intercepted by radio receiving
equipment within range of the cordless handset. For this reason, you should
not think of cordless telephone conversations as being as private as those on
corded telephones.
Electrical power: The telephone base of this cordless telephone must be
connected to a working electrical outlet which is not controlled by a wall
switch. Calls cannot be made from the handset if the telephone base is
unplugged, switched off or if the electrical power is interrupted.
Potential TV interference: Some cordless telephones operate at frequencies
that may cause interference to TVs and VCRs. To minimize or prevent
such interference, do not place the telephone base of the cordless telephone
near or on top of a TV or VCR. If interference is experienced, moving the
cordless telephone farther away from the TV or VCR will often reduce or
eliminate the interference.
Rechargeable batteries: This product contains nickel-metal hydride
rechargeable batteries. Exercise care in handling batteries in order not to
create a short circuit with conductive material such as rings, bracelets, and
keys. The battery or conductor may overheat and cause harm. Observe proper
polarity between the battery and the battery charger.
Nickel-metal hydride rechargeable batteries: 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.
The RBRC™ Seal means that the manufacturer is voluntarily
participating in an industry program to collect and recycle
nickel-metal hydride rechargeable batteries when taken out
of service within the United States. These batteries may be
taken to a participating local retailer of replacement batteries
or recycling center. Or you may call 1 (800) 8-BATTERY for
locations accepting spent Ni-MH batteries.

Precautions for users of implanted cardiac pacemakers
Cardiac pacemakers (applies only to digital cordless telephones):
Wireless Technology Research, LLC (WTR), an independent research entity, led
a multidisciplinary evaluation of the interference between portable wireless
telephones and implanted cardiac pacemakers. Supported by the U.S. Food and
Drug Administration, WTR recommends to physicians that:
Pacemaker patients
Should keep wireless telephones at least six inches from the pacemaker.
Should NOT place wireless telephones directly over the pacemaker, such as in
a breast pocket, when it is turned ON.
Should use the wireless telephone at the ear opposite the pacemaker.
WTR’s evaluation did not identify any risk to bystanders with pacemakers from
other persons using wireless telephones.
Especially about telephone answering systems
Two-way recording: This unit does not sound warning beeps to inform the other
party that the call is being recorded. To ensure that you are in compliance with
any federal or state regulations regarding recording a telephone call, you should
start the recording process and then inform the other party that you are recording
the conversation.
