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, re, or electric shock.
Safety information
fRead and understand all instructions in the user’s manual. Observe all markings
on the product.
fAvoid using a telephone during a thunderstorm. There may be a slight chance of
electric shock from lightning.
fDo 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. 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 ammable or ame-
supporting gases. A spark in such an environment could create a re 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.
fDo not use this product near water or when you are wet. For example, do not
use 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.
fInstall this product in a protected location where no one can trip over any line or
power cords. Protect cords from damage or abrasion.
fIf this product does not operate normally, see the Troubleshooting section of
the online Complete user’s manual. If you cannot solve the problem, or if the
product is damaged, refer to the Limited warranty section (pages 28 - 30).
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.
fReplace batteries, only as described in your user’s manual (Page 5). Do not
burn or puncture batteries — they contain caustic chemicals.
fThis power adapter is intended to be correctly oriented in a vertical or oor
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.
fFor pluggable equipment, the socket-outlet shall be installed near the equipment
and shall be easily accessible.

Important safety information
CAUTIONS:
fUse only the power adapter provided with this product. To obtain a replacement,
visit our website at https://telephones.att.com or call
1 [phone]. In Canada, dial 1 [phone].
fU se only the supplied rechargeable battery or replacement battery (model BT183342/
BT283342). To order, visit our website at
https://telephones.att.com, or call 1 [phone].In
Canada, dial 1 [phone].
CAUTION: To prevent risk of re or battery explosion, replace with
the correct battery type. Dispose of used batteries according to the
instructions.
Especially about cordless telephones
fPrivacy: 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.
fElectrical 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 o or if the electrical power is interrupted.
fPotential 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 oen reduce or eliminate the
interference.
fRechargeable 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.
fNickel-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.

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:
fShould keep wireless telephones at least six inches from the pacemaker.
fShould NOT place wireless telephones directly over the pacemaker, such as in a
breast pocket, when it is turned ON.
fShould 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.
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.
