safety and usage information9Exposure 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. 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 togive additional protection to the public and toaccount for any variations in measurements.SAR tests are conducted using standard operatingpositions accepted by the FCC with the phonetransmitting at its highest certified power level in alltested frequency bands. Although the SAR isdetermined at the highest certified power level, theactual SAR level of the phone while operating can bewell below the maximum value. This is because thephone is designed to operate at multiple powerlevels so as to use only the power required to reach
