Especially about cordless telephones Privacy: The same features that make a cordless telephone convenient create some limitations. Telephone calls are trans- mitted 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 equip- ment 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. Electrical power: The telephone base of this cordless tele- phone 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. 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. 15 ****** Page 19 ****** Appendix B Important safety information • Rechargeable batteries: This product contains either nickel- cadmium or nickel-metal hydride rechargeable batteries. Exer- cise 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. 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 ecycze 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. Or you may call 1-800-8-BATTERY for locations accepting spent Ni-MH batteries. Precautions for users of implanted cardiac pacemakers Cardiac pacemakers (applies only to digital cordless telephones): Wireless Technology Research, LLC (WTR), an independent re- search 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: 16 ****** Page 20 ****** Appendix B Important safety information PACEMAKER PATIENTS • Should keep wireless telephones at least six inches from the pacemaker. • Should NOT place wireless telephones directly over the pace- maker, such as in a breast pocket, when it is turned ON. • Should 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.
