Appendix
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 might be a slight chance of electric
shock from lightning.
Do not use a telephone in the vicinity of a gas 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 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, read Troubleshooting in this user’s manual
(pages 53-59). If you cannot solve the problem, or if the product is damaged, refer to Limited
warranty on pages 65-66. 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.
If this product has a three-prong (grounding) plug or a polarized plug with one wide
prong, it might not fit in outlets that are not polarized. Do not defeat the purpose of these
plugs. If they do not fit in your outlet, the outlet should be replaced by an electrician.
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 corded telephones
Electrical power: The telephone base must be connected to a working electrical outlet. The
electrical outlet should not be 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.
Power adapter: The 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, under-the-table or cabinet outlet.
