Health and Safety Information 123Section 16: Health and Safety InformationThis section outlines the safety precautions associated with usingyour phone. These safety precautions should be followed to safelyuse your phone.Health 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 limits forradio 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 NationalCounsel on Radiation Protection and Measurement (NCRP) andthe Institute of Electrical and Electronics Engineers (IEEE).In both cases, the recommendations were developed by scientificand engineering experts drawn from industry, government, andacademia after extensive reviews of the scientific literaturerelated 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 units ofwatts per kilogram (W/kg). The FCC requires wireless phones tocomply with a safety limit of 1.6 watts per kilogram (1.6 W/kg).The FCC exposure limit incorporates a substantial margin ofsafety to give additional protection to the public and to accountfor 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. Although theSAR is determined at the highest certified power level, the actualSAR level of the phone while operating can be well below themaximum value. This is because the phone is designed tooperate at multiple power levels so as to use only the powerrequired to reach the network. In general, the closer you are to awireless base station antenna, the lower the power output.Before a new model phone is available for sale to the public, itmust be tested and certified to the FCC that it does not exceedthe exposure limit established by the FCC. Tests for each modelphone are performed in positions and locations (e.g. at the earand worn on the body) as required by the FCC.
