124Section 13: Health and Safety InformationTopics Covered• Health and Safety InformationThis section outlines the safety precautions associated with using your phone. Thesesafety precautions should be followed to safely use your phone.Health and Safety InformationExposure to Radio Frequency (RF) SignalsCertification Information (SAR)Your wireless phone is a radio transmitter and receiver. It is designed andmanufactured not to exceed the exposure limits for radio frequency (RF) energy setby the Federal Communications Commission (FCC) of the U.S. government. TheseFCC exposure limits are derived from the recommendations of two expertorganizations, the National Counsel on Radiation Protection and Measurement(NCRP) and the Institute of Electrical and Electronics Engineers (IEEE). In both cases,the recommendations were developed by scientific and engineering experts drawnfrom industry, government, and academia after extensive reviews of the scientificliterature related to the biological effects of RF energy.The exposure limit set by the FCC for wireless mobile phones employs a unit ofmeasurement known as the Specific Absorption Rate (SAR). The SAR is a measureof the rate of absorption of RF energy by the human body expressed in units of wattsper kilogram (W/kg). The FCC requires wireless phones to comply with a safety limitof 1.6 watts per kilogram (1.6 W/kg). The FCC exposure limit incorporates asubstantial margin of safety to give additional protection to the public and to accountfor any variations in measurements.SAR tests are conducted using standard operating positions accepted by the FCCwith the phone transmitting at its highest certified power level in all tested frequencybands. Although the SAR is determined at the highest certified power level, theactual SAR level of the phone while operating can be well below the maximum value.This is because the phone is designed to operate at multiple power levels so as touse only the power required to reach the network. In general, the closer you are to awireless base station antenna, the lower the power output.
