safety and usage information19Do wireless phone accessories thatclaim to shield the head from RFradiation work?Since there are no known risks from exposure to RFemissions from wireless phones, there is no reasonto believe that accessories that claim to shield thehead from those emissions reduce risks. Someproducts that claim to shield the user from RFabsorption use special phone cases, while othersinvolve nothing more than a metallic accessoryattached to the phone. Studies have shown thatthese products generally do not work as advertised.Unlike “hand-free” kits, these so-called “shields” mayinterfere with proper operation of the phone. Thephone may be forced to boost its power tocompensate, leading to an increase in RFabsorption. In February 2002, the Federal tradeCommission (FTC) charged two companies that solddevices that claimed to protect wireless phone usersfrom radiation with making false and unsubstantiatedclaims. According to FTC, these defendants lackeda reasonable basis to substantiate their claim.
