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.  
13  
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

14  
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.  
15  
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:  
16  
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.

your wiring or local service. Contact your  
local telephone company (charges may  
apply).

another phone has the same problem, the  
problem is the phone jack. Contact your
