It is designed and manufactured not toexceed the exposure limits for radio frequency (RF)energy set by the Federal CommunicationsCommission (FCC) of the U.S. government. TheseFCC exposure limits are derived from therecommendations of two expert organizations, theNational Counsel on Radiation Protection andMeasurement (NCRP) and the Institute of Electricaland Electronics Engineers (IEEE). In both cases, therecommendations were developed by scientific andengineering experts drawn from industry,government, and academia after extensive reviewsof the scientific literature related to the biologicaleffects of RF energy.The exposure limit set by the FCC for wirelessmobile phones employs a unit of measurementknown as the Specific Absorption Rate (SAR). TheSAR is a measure of the rate of absorption of RFenergy by the human body expressed in units ofwatts per kilogram (W/kg). The FCC requireswireless phones to comply with a safety limit of 1.6watts per kilogram (1.6 W/kg). The FCC exposurelimit incorporates a substantial margin of safety to
