167Section 13: Health and Safety InformationThis section outlines the safety precautions associated with using your phone. These safety precautions should befollowed 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 and manufactured not to exceed the exposurelimits for radio frequency (RF) energy set by the Federal Communications Commission (FCC) of the U.S. government.These FCC exposure limits are derived from the recommendations of two expert organizations, the National Counselon 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 drawn from industry,government, and academia after extensive reviews of the scientific literature related to the biological effects of RFenergy.The exposure limit set by the FCC for wireless mobile phones employs a unit of measurement known as the SpecificAbsorption Rate (SAR). The SAR is a measure of the rate of absorption of RF energy by the human body expressed inunits of watts per kilogram (W/kg). The FCC requires wireless phones to comply with a safety limit of 1.6 watts perkilogram (1.6 W/kg).The FCC exposure limit incorporates a substantial margin of safety to give additional protection to the public and toaccount for any variations in measurements.SAR tests are conducted using standard operating positions accepted by the FCC with the phone transmitting at itshighest certified power level in all tested frequency bands. Although the SAR is determined at the highest certifiedpower level, the actual SAR level of the phone while operating can be well below the maximum value. This isbecause the phone is designed to operate at multiple power levels so as to use only the power required to reach thenetwork. In general, the closer you are to a wireless base station antenna, the lower the power output.Before a new model phone is available for sale to the public, it must be tested and certified to the FCC that it doesnot exceed the exposure limit established by the FCC. Tests for each model phone are performed in positions andlocations (e.g. at the ear and worn on the body) as required by the FCC.
