128Appendix/TroubleshootingTo refer to details (including certification numbers) on authorization andcompliance mark particular to the FOMA terminal, perform the followingoperation.From the Home screen, w "Settings" "About device""Regulatory".• This device complies with part 15 of the FCC Rules. Operation is subjectto the following two conditions:(1) This device may not cause harmful interference, and (2) this devicemust accept any interference received, including interference that maycause undesired operation.• Changes or modifications not expressly approved by the manufacturerresponsible for compliance could void the user's authority to operate theequipment.■ Information to UserThis equipment has been tested and found to comply with the limits of aClass B digital device, pursuant to Part 15 of the FCC Rules.These limits are designed to provide reasonable protection againstharmful interference in a residential installation. This equipmentgenerates, uses and can radiate radio frequency energy and, if notinstalled and used in accordance with the instructions, may causeharmful interference to radio communications.However, there is no guarantee that interference will not occur in aparticular installation; if this equipment does cause harmful interferenceto radio or television reception, which can be determined by turning theequipment off and on, the user is encouraged to try to correct theinterference by one or more of the following measures:1. Reorient/relocate the receiving antenna.2. Increase the separation between the equipment and receiver.3. Connect the equipment into an outlet on a circuit different from that towhich the receiver is connected.4. Consult the dealer or an experienced radio/TV technician for help.Your device is a radio transmitter and receiver. It is designed andmanufactured not to exceed the exposure limits for radiofrequency (RF)energy set by the Federal Communications Commission (FCC) of the U.S.Government.These FCC exposure limits are derived from the recommendations of twoexpert organizations: the National Council on Radiation Protection andMeasurement (NCRP) and the Institute of Electrical and ElectronicsEngineers (IEEE).In both cases, the recommendations were developed by scientific andengineering experts drawn from industry, government, and academia afterextensive reviews of the scientific literature related to the biological effects ofRF energy.The exposure limit set by the FCC for wireless devices employs a unit ofmeasurement known as the Specific Absorption Rate (SAR). The SAR is ameasure of the rate of absorption of RF energy by the human bodyexpressed in units of watts per kilogram (W/kg). The FCC requires wirelessdevices to comply with a safety limit of 1.6 watts per kilogram (1.6 W/kg).The FCC exposure limit incorporates a substantial margin of safety to giveadditional protection to the public and to account for any variations inmeasurements.SAR tests are conducted using standard operating positions accepted by theFCC with the device transmitting at its highest certified power level in alltested frequency bands. Although the SAR is determined at the highestcertified power level, the actual SAR level of the device while operating canbe well below the maximum value. This is because the device is designed tooperate at multiple power levels so as to use only the power required toreach the network. In general, the closer you are to a wireless base stationantenna, the lower the power output.Authorization and ComplianceFCC noticeFCC RF exposure information
