Nokia Lumia 822: Safety and WarrantyChapter 16The highest SAR value under the ICNIRP guidelines for use of the deviceat the ear is 0.79 W/kg.Use of device accessories may result in different SAR values. SAR valuesmay vary depending on national reporting and testing requirementsand the network band. Additional SAR information may be providedunder product information at www.nokia.com.Your mobile device is also designed to meet the requirements for expo-sure to radio waves established by the Federal Communications Com-mission (USA) and Industry Canada.These requirements set a SAR limit of 1.6 W/kg averaged over one gramof tissue. The highest SAR value reported under this standard duringproduct certification for use at the ear is 1.23 W/kg and when properlyworn on the body is 1.03 W/kg.Message from the FDAThe U.S. Food and Drug Administration (FDA) provides the followingconsumer information about wireless phones.See http://www.fda.gov/cellphones for updated information.Do wireless phones pose a health hazard?The available scientific evidence does not show that any health prob-lems are associated with using wireless phones. There is no proof, how-ever, that wireless phones are absolutely safe. Wireless phones emitlow levels of radio frequency energy (RF) in the microwave range whilebeing used. They also emit very low levels of RF when in the stand-bymode. Whereas high levels of RF can produce health effects (by heatingtissue), exposure to low level RF that does not produce heating effectscauses no known adverse health effects. Many studies of low level RFexposures have not found any biological effects. Some studies havesuggested that some biological effects may occur, but such findingshave not been confirmed by additional research. In some cases, otherresearchers have had difficulty in reproducing those studies, or in deter-mining the reasons for inconsistent results.What is the FDA’s role concerning the safety of wirelessphones?Under the law, FDA does not review the safety of radiation emittingconsumer products such as wireless phones before they can be sold,as it does with new drugs or medical devices. However, the agencyhas authority to take action if wireless phones are shown to emit radiofrequency energy (RF) at a level that is hazardous to the user. In such acase, FDA could require the manufacturers of wireless phones to notifyusers of the health hazard and to repair, replace or recall the phones sothat the hazard no longer exists. Although the existing scientific datado not justify FDA regulatory actions, FDA has urged the wireless phoneindustry to take a number of steps, including the following:• Support needed research into possible biological effects of RF ofthe type emitted by wireless phones;• Design wireless phones in a way that minimizes any RF exposure tothe user that is not necessary for device function;• Cooperate in providing users of wireless phones with the bestpossible information on possible effects of wireless phone use onhuman health.FDA belongs to an interagency working group of the federal agenciesthat have responsibility for different aspects of RF safety to ensurecoordinated efforts at the federal level.The following agencies belong to this working group:• National Institute for Occupational Safety and Health• Environmental Protection Agency• Federal Communications Commission• Occupational Safety and Health Administration• National Telecommunications and Information AdministrationThe National Institutes of Health participates in some interagencyworking group activities, as well.FDA shares regulatory responsibilities for wireless phones with theFederal Communications Commission (FCC). All phones that are sold inthe United States must comply with FCC safety guidelines that limit RFexposure. FCC relies on FDA and other health agencies for safety ques-71
