108Health 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 theexposure limits for radio frequency (RF) energy set bythe Federal Communications Commission (FCC) of theU.S. government. These FCC exposure limits arederived from the recommendations of two expertorganizations, the National Counsel on RadiationProtection and Measurement (NCRP) and the Instituteof Electrical and Electronics Engineers (IEEE). In bothcases, the recommendations were developed byscientific and engineering experts drawn fromindustry, government, and academia after extensivereviews of the scientific literature related to thebiological effects of RF energy.The exposure limit set by the FCC for wireless mobilephones employs a unit of measurement known as theSpecific Absorption Rate (SAR). The SAR is a measureof the rate of absorption of RF energy by the humanbody expressed in units of watts per kilogram (W/kg).The FCC requires wireless phones to comply with asafety limit of 1.6 watts per kilogram (1.6 W/kg). TheFCC exposure limit incorporates a substantial marginof safety to give additional protection to the public andto account 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 power levelsso as to use only the power required to reach thenetwork. In general, the closer you are to a wirelessbase station antenna, the lower the power output.
