Health and Safety Information153Health and Safety InformationExposure to Radio Frequency (RF) SignalsCertification Information (SAR)Your wireless phone is a radio transmitter and receiver. It isdesigned and manufactured not to exceed the exposure limitsfor radio frequency (RF) energy set by the FederalCommunications Commission (FCC) of the U.S. government.These FCC exposure limits are derived from therecommendations of two expert organizations, the NationalCounsel on Radiation Protection and Measurement (NCRP)and the Institute of Electrical and Electronics Engineers (IEEE).In both cases, the recommendations were developed byscientific and engineering experts drawn from industry,government, and academia after extensive reviews of thescientific literature related to the biological effects of RF energy.The exposure limit set by the FCC for wireless mobile phonesemploys a unit of measurement known as the SpecificAbsorption Rate (SAR). The SAR is a measure of the rate ofabsorption of RF energy by the human body expressed in unitsof watts per kilogram (W/kg). The FCC requires wirelessphones to comply with a safety limit of 1.6 watts per kilogram(1.6 W/kg). The FCC exposure limit incorporates a substantialmargin of safety to give additional protection to the public andto account for any variations in measurements.SAR tests are conducted using standard operating positionsaccepted by the FCC with the phone transmitting at its highestcertified power level in all tested frequency bands.
