158Specific Absorption Rate (SAR)Certification InformationYour 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.These FCC exposure limits are derived from therecommendations of two expert organizations: theNational Council on Radiation Protection andMeasurement (NCRP) and the Institute of Electricaland Electronics Engineers (IEEE).In both cases, the recommendations were developedby scientific 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).The FCC exposure limit incorporates a substantialmargin of safety to give additional protection to thepublic and to account for any variations inmeasurements.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.Before a new model phone is available for sale to thepublic, it must be tested and certified to the FCC thatit does not exceed the exposure limit established bythe FCC. Tests for each model phone are performed inpositions and locations (e.g. at the ear and worn onthe body) as required by the FCC.For body-worn operation, this phone has been testedand meets FCC RF exposure guidelines when usedwith an accessory that contains no metal and thatpositions the mobile device a minimum of 1.5 cmfrom the body.Use of other accessories may not ensure compliancewith FCC RF exposure guidelines.The FCC has granted an Equipment Authorization forthis mobile phone with all reported SAR levelsevaluated as in compliance with the FCC RF exposureguidelines. The maximum SAR values for this modelphone as reported to the FCC are:• Head: 0.91 W/Kg.• Body-worn: 1.12 W/Kg.2.4GHZ WLAN• Head: 0.28 W/Kg.• Body-worn: 0.16 W/Kg.
