48Exposure to Radio Frequency (RF) SignalsYour wireless device is a radio transmitter and receiver.It is designed and manufactured not to exceed theexposure limits for radio frequency (RF) energy set bythe Federal Communications Commission (FCC) of theU.S. government. These FCC exposure limits are derivedfrom the recommendations of two expert organizations,the National Counsel on Radiation Protection andMeasurement (NCRP) and the Institute of Electricaland Electronics Engineers (IEEE). In both cases, theengineering experts drawn from industry, government,The exposure limit set by the FCC for wireless mobiledevices employs a unit of measurement known as thethe rate of absorption of RF energy by the human bodyexpressed in units of watts per kilogram (W/kg). The FCCrequires wireless devices to comply with a safety limitof 1.6 watts per kilogram (1.6 W/kg). The FCC exposurelimit incorporates a substantial margin of safety to giveadditional protection to the public and to account forany variations in measurements.SAR tests are conducted using recommended operatingpositions accepted by the FCC with thetested frequency bands. Although the SAR is determinedof the whi e operating can be we l below themaximum value. This is because the is designedto operate at multiple power levels so as to use only thepower required to reach the network. In general, thecloser you are to a wireless base station antenna, thelower the power output.Before a new model device is available for sale to theit does not exceed the exposure limit established bythe FCC. Tests for each model are per ormed inpositions and locations (e.g. near the body) as requiredby the FCC.Health and safety informationFor typical operations, this model has beentested and meets the FCC exposure guidelines.SAR information on this and other model canbe viewed on-line at http://www.fcc.gov/oet/ea/fccid/.This site uses the FCC ID number A3LSMP350.You can check the FCC ID on the rear case.Once you have the FCC ID number for a particular ,follow the instructions on the website and it shouldprovide values for typical or maximum SAR fora particularSAR information can also be obtained at www.fcc.gov/cgb/sar.Operating EnvironmentRemember to follow any special regulations in force inany area and always switch yourforbidden to use it, or when it may cause interference ordanger. When connecting the or any a cessor toanother device, read its user’s guide for detailed safetyinstructions. Do not connect incompatible products.
