The FCC database does not list phones by model number. However,consumers may find SAR information from other sources as well. Somewireless phone manufacturers make SAR information available on theirown Web sites. In addition, some non-government Web sites provide SARsfor specific models of wireless phones. However, the FCC has not reviewedthese sites and makes no guarantees of their accuracy. Finally, phonescertified by the Cellular Telecommunications and Internet Association(CTIA) are required to provide SAR information to consumers in theinstructional materials that come with the phones.8. Do hands-free kits for wireless phones reduce risks fromexposure to RF emissions?Since there are no known risks from exposure to RF emissions fromwireless phones, there is no reason to believe that hands-free kits reducerisks. Hands-free kits can be used with wireless phones for convenienceand comfort. These systems reduce the absorption of RF energy in thehead because the phone, which is the source of the RF emissions, will notbe placed against the head. On the other hand, if the phone is mountedagainst the waist or other part of the body during use, then that part ofthe body will absorb more RF energy. Wireless phones marketed in theU.S. are required to meet safety requirements regardless of whether theyare used against the head or against the body. Either configurationshould result in compliance with the safety limit.9. Do wireless phone accessories that claim to shield the headfrom RF radiation work?Since there are no known risks from exposure to RF emissions fromwireless phones, there is no reason to believe that accessories that claimto shield the head from those emissions reduce risks. Some products thatclaim to shield the user from RF absorption use special phone cases,while others involve nothing more than a metallic accessory attached tothe phone. Studies have shown that these products generally do not workas advertised. Unlike “hand-free” kits, these so-called “shields” mayinterfere with proper operation of the phone. The phone may be forced toboost its power to compensate, leading to an increase in RF absorption.In February 2002, the Federal trade Commission (FTC) charged twocompanies that sold devices that claimed to protect wireless phoneSection 4: Safety Guidelines and Warranty Information4A: Safety197
