86causes brain tumors or other ill effects. Theirrecommendation to limit cell phone use by childrenwas strictly precautionary; it was not based onscientific evidence that any health hazard exists.Additional information on the safety of RF exposuresfrom various sources can be obtained from thefollowing organizations (updated 10/1/2010):• FCC RF Safety Program:http://www.fcc.gov/oet/rfsafety/.• Environmental Protection Agency (EPA):http://www.epa.gov/radtown/wireless-tech.html.• Occupational Safety and Health Administration (OSHA):http://www.osha.gov/SLTC/radiofrequencyradiation/.(Note: This web address is case sensitive.)• National Institute for Occupational Safety and Health(NIOSH):http://www.cdc.gov/niosh/.• World Health Organization (WHO):http://www.who.int/peh-emf/en/.• International Commission on Non-Ionizing RadiationProtection:http://www.icnirp.de.• Health Protection Agency:http://www.hpa.org.uk/Topics/Radiation/.• US Food and Drug Administration:http://www.fda.gov/Radiation-EmittingProducts/RadiationEmittingProductsandProcedures/HomeBusinessandEntertainment/CellPhones/default.htm.Specific 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.
