This is a common event associated with the closing of any electrical circuit. In an inadequately ventilated environment, the user should not plug the phone into a power outlet, nor put a charged handset into the cradle where there are concentrations of flammable or flame-

supporting gases. 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. f Do not use this product near water or when you are wet. For example, do not use f f it in a wet basement or shower, nor next to a swimming pool, bathtub, kitchen sink and 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 Use only the power adapter provided with this product. To obtain a replacement, visit our website at https://telephones.att.com or call 1 (800) 222-3111. In Canada, dial 1 (866) 288-4268. 1 Getting started Important safety information i CAUTION: To prevent risk of fire or battery explosion, replace with the correct battery type. Dispose of used batteries according to the instructions. f Disconnect the telephone line from the equipment before open the battery door. Do not use the battery in following conditions:

f High or low extreme temperature during use, storage or transportation. f Replacement of a battery with an incorrect type that can defeat a safeguard. f Disposal of a battery into fire or a hot oven, or mechanically crushing or cutting of a battery, that can result in an explosion. f Leaving a battery in an extremely high temperature surrounding environment that can result in an explosion or the leakage of flammable liquid or gas. f A battery subjected toextremely low air pressure that can result in an explosion or the leakage of flammable liquid or gas. f Use only the supplied rechargeable battery or replacement battery (model BT162342/BT262342). To order, visit our website at https://telephones.att.com, or call 1 (800) 222-3111. In Canada, dial 1 (866) 288-4268. f The applied nameplate is located at the bottom or near of the product. Especially about cordless telephones f 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. f 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. f 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. f 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. 2 Getting started Important safety information f 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. You may call 1-800-8-BATTERY for locations accepting spent Ni-MH batteries. The RBRC Seal and 1-800-8-BATTERY are registered trademarks of Call2recycle, Inc. 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:

f Should keep wireless telephones at least six inches from the pacemaker. f Should NOT place wireless telephones directly over the pacemaker, such as in a breast pocket, when it is turned ON. f Should use the wireless telephone at the ear opposite the pacemaker. WTRs evaluation did not identify any risk to bystanders with pacemakers from other persons using wireless telephones. ECO mode This power conserving technology reduces power consumption for optimal battery performance. The ECO mode activates automatically whenever the handset is synchronized with the telephone base. 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.
