Appendix A

Maintenance

Taking care of your telephone

• Your cordless telephone contains sophisticated electronic parts,

so it must be treated with care.

• Avoid rough treatment.

• Place the handset down gently.

• Save the original packing materials to protect your telephone if

you ever need to ship it.

Avoid water

• Your telephone can be damaged if it gets wet. Do not use the

handset outdoors in the rain, or handle it with wet hands. Do not

install the telephone base 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 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.

Remember that electrical appliances can cause serious injury if used when you

are wet or standing in water. If the telephone base should fall into water, DO NOT

RETRIEVE IT UNTIL YOU UNPLUG THE POWER CORD AND TELEPHONE LINE CORDS

FROM THE WALL. Then pull the unit out by the unplugged cords.

Appendix B

Important safety information

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 a telephone in the vicinity of a gas leak. If you

suspect a gas leak, report it immediately, but use a telephone

away from the area where gas is leaking. If this product is a

cordless model, make sure the telephone base is also away from

the area.

• 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 liquids, 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.

• If this product does not operate normally, see the

Troubleshooting section on pages 28-37 of this user’s manual.

If you cannot solve the problem, or if the product is damaged,

refer to the Limited warranty on pages 23-26. Do not open

this product except as may be directed in your user’s manual.

Opening the product or reassembling it incorrectly may expose

you to hazardous voltages or other risks.

Appendix B

Important safety information

• Replace batteries only as described in your user’s manual.

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 or an

under-the-table/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 (800) 222-3111.

In Canada, dial 1 (866) 288-4268.

Especially about cordless telephones

•

Privacy: The same features that make a cordless telephone

convenient create some limitations. Telephone calls are trans-

mitted 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 equip-

ment 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 tele-

phone 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.

Appendix B

Important safety information

•

Rechargeable batteries: This product contains either nickel-

cadmium or nickel-metal hydride rechargeable batteries. Exer-

cise 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 re-

search 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:

Appendix B

Important safety information

PACEMAKER PATIENTS

• Should keep wireless telephones at least six inches from the

pacemaker.

• Should NOT place wireless telephones directly over the pace-

maker, 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.
