Health and safety information44Health and safety informationExposure to Radio Frequency (RF)SignalsCertification Information (SAR)Your wireless phone is a radio transmitter andreceiver. 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.These FCC exposure limits are derived from therecommendations of two expert organizations,the National Counsel on Radiation Protectionand Measurement (NCRP) and the Institute ofElectrical and Electronics Engineers (IEEE). Inboth cases, the recommendations weredeveloped by scientific and engineering expertsdrawn from industry, government, andacademia after extensive reviews of thescientific 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).The SAR is a measure of the rate of absorptionof RF energy by the human body expressed inunits of watts per kilogram (W/kg). The FCCrequires wireless phones to comply with asafety limit of 1.6 watts per kilogram (1.6 W/kg). The FCC exposure limit incorporates asubstantial margin of safety to give additionalprotection to the public and to account for anyvariations in measurements.SAR tests are conducted using standardoperating positions accepted by the FCC withthe phone transmitting at its highest certifiedpower level in all tested frequency bands.Although the SAR is determined at the highestcertified power level, the actual SAR level of thephone while operating can be well below themaximum value.
