87Health and safety informationExposure to Radio Frequency(RF) SignalsYour wireless phone is a radio transmitter andreceiver. It is designed and manufactured not toexceed the emission limits for exposure to radiofrequency (RF) energy set by the FederalCommunications Commission (FCC) of the U.S.Government. These limits are part ofcomprehensive guidelines and establishpermitted levels of RF energy for the generalpopulation. The guidelines are based on thesafety standards that were developed byindependent scientific organizations throughperiodic and through evaluation of scientificstudies.The standards include a substantial safety margindesigned to assure the safety of all persons,regardless of age and health.The exposure standard for wireless phonesemploys a unit of measurement known asSpecific Absorption Rate (SAR). The SAR limit setby the FCC is 1.6W/kg*.*In the U.S. and Canada, the SAR limit for mobile phonesused by the public is 1.6 watts/kg (W/kg)averaged over one gram of tissue. The standardincorporates a substantial margin of safety to giveadditional protection for the public and to account for anyvariations in measurements.
