It isdesigned and manufactured not to exceed the exposurelimits for Radio Frequency (RF) energy set by the FederalCommunications Commission (FCC) of the U.S. Government.These FCC RF exposure limits are derived from therecommendations of two expert organizations: the NationalCouncil on Radiation Protection and Measurement (NCRP)and the Institute of Electrical and Electronics Engineers(IEEE). In both cases, the recommendations were developedby scientific and engineering experts drawn from industry,government, and academia after extensive reviews of thescientific literature related to the biological effects of RFenergy.The RF exposure limit set by the FCC for wireless mobilephones employs a unit of measurement known as theSpecific Absorption Rate (SAR). The SAR is a measure of therate of absorption of RF energy by the human bodyexpressed in units of watts per kilogram (W/kg). The FCCrequires wireless phones to comply with a safety limit of 1.6watts per kilogram (1.6 W/kg).The FCC SAR limit incorporates a substantial margin of safetyto give additional protection to the public and to account forany variations in measurements.SAR tests are conducted using standard operating positionsaccepted 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 whileoperating can be well below the maximum reported value.This is because the phone is designed to operate at multiplepower levels so as to use only the power required to reachthe network. In general, the closer you are to a wireless basestation antenna, the lower the power output of the phone.Before a new model phone is available for sale to the public,it must be tested and certified to the FCC that it does notexceed the SAR limit established by the FCC. Tests for eachmodel phone are performed in positions and locations (e.g. atthe ear and worn on the body) as required by the FCC. Forbody-worn operation, this phone has been tested and meets
