IMPORTANT PRODUCT INFORMATION 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. 1Read and understand all instructions in the user’s manual. Observe all markings on the product. 2Avoid using a telephone during a thunderstorm. There may be a slight chance of electric shock from lightning. 3Do 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 base is also away from the area. 4Do 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. 5Install this product in a protected location where no one can trip over any line or power cords. Protect cords from damage or abrasion. 6If this product does not operate normally, read “In Case of Difficulty” in the user’s manual. If you cannot solve the problem, or if the product is damaged, refer to the Limited Warranty. 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. Part 1 (Continued) © 2001 Advanced American Telephones. All Rights Reserved. AT&T and the Globe Design are trademarks of AT&T Corp., licensed to Advanced American Telephones. 2 7If this product has user-replaceable batteries, replace batteries only as described in your user’s manual. Do not burn or puncture batteries — they contain caustic chemicals. 8If this product has a three-prong (grounding) plug or a polarized plug with one wide prong, it may not fit in non-polarized outlets. 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, call 1 800 222–3111. SAVE THESE INSTRUCTIONS Especially About Cordless Telephones Privacy: The same features that make a cordless phone convenient create some limitations. Telephone calls are transmitted between the base and the handset by radio waves, so there is a possibility that your cordless phone conversations could be intercepted by radio receiving equipment within range of the cordless handset. For this reason, you should not think of cordless phone conversations as being as private as those on corded phones. Electrical Power:The base unit of this cordless telephone 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 base unit is unplugged or 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 base unit 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. (Applies to 25-channel cordless phones only.) Rechargeable Batteries:This product contains either Nickel- Cadmium or Nickel-Metal Hydride rechargeable batteries. Exercise care in handling batteries in order not to short the battery with conducting 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. 3 Nickel-Cadmium Rechargeable Batteries:Must be recycled or disposed of properly. Do not dispose of in household garbage. 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-Cadmium 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 8BATTERY for locations accepting spent Nickel-Cadmium Batteries. 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. Precautions for Users of Implanted Cardiac Pacemakers Cardiac Pacemakers (applies only to 900 MHz 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 had recommended to physicians that: PACEMAKER PATIENTS •Should keep wireless phones at least six inches from the pacemaker •Should NOTplace wireless phones directly over the pacemaker, such as in a breast pocket, when it is turned ON •Should use the wireless phone at the ear opposite the pacemaker WTR’s evaluation did not identify any risk to bystanders with pacemakers from other persons using wireless phones. 4 Especially About Telephone Answering Systems Two-Way Recording:This unit does not sound warning beeps to let the other party know 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 …

Canada V6X 1Z9 Tel: (604) 273-5131 Fax: (604) 276-9137 Radio Frequency Exposure Information For AT&T E2525 / E2555 Cordless Handset Handset (Tx / Rx: 2.4GHz band) Readings from test report : (1) Max. Output Power = 122.6 mW (20.9 dBm) (2) Duty cycle – 1ms / 10ms = 10% (measured in single slot transmission) Under the worst environment with interference, dual slot diversity gives the max. duty cycle on the handset Tx (ie. 10% x2 or 20%) Hence, taking the max. power output & max. duty cycle, the average effective output power is : 122.6 mW x 20% = 24.52 mW Conclusion : The average effective output power is lower than the low threshold level (25mW) of portable device that operates less than 20cm from a person’s body. Hence, there is no RF exposure concerns on handset.
