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, Pt1_1yr_Eng_China_5ATT 5/20/02 12:20 PM Page 2 3 bracelets, and keys. The battery or conductor may overheat and cause harm. Observe proper polarity between the battery and the battery charger. 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.

Radio Frequency Exposure Information For AT&T 2230 LC (low cost) 2.4GHz Cordless Telephone Handset : Readings from test report : (1) Max. Output Power – Ant. A = 0.1W ; Ant. B = 0.08W (2) Duty cycle – 750us x10 / 100ms = 7.5% (measured in single slot transmission) Under the worst environment with interference, dual slot diversity gives the max. duty cycle on the handset Tx (ie. 7.5% x2 or 15%) Hence, taking the max. power output & max. duty cycle, the average effective output power is : 0.1W x 15% = 0.015W or 15mW Conclusion : The average effective output power is much lower than the 50mW level (Supplement C, Table 1) which starts to require SAR testing. Hence, there is no RF exposure concerns on handset. Base : Readings from test report : (1) Max. Output Power – 0.15W (2) Duty Cycle – 750us x15 / 100ms = 11.25% (with single handset & dummy carriers) The phone is a TDD, FHSS. So, the worst case is actually operating with 4 handsets (750us x40 / 100ms, or 30%). Hence, taking the worst case, the average effective output power is : 0.15W x 30% = 0.045W or 45mW Conclusion : The base of a cordless phone system is not normally operated close to the users as that of the handset. Together with the low average effective output power, the base is also with no concerns on RF exposure. Joseph Poon Regulatory Compliance Manager VTech E ngineering Ca nada Ltd.
