A d d i t i o n a l s a f e t y i n f o r m a t i o n79The exposure guidelines for mobile devices employ a unit of measurement knownas the Specific Absorption Rate or SAR. The SAR limit stated in the ICNIRP guidelinesis 2.0 watts/kilogram (W/kg) averaged over 10 grams of tissue. Tests for SAR areconducted using standard operating positions with the device transmitting at itshighest certified power level in all tested frequency bands. The actual SAR levelof an operating device can be below the maximum value because the deviceis designed to use only the power required to reach the network. That amountchanges depending on a number of factors such as how close you are to a networkbase station. The highest SAR value under the ICNIRP guidelines for use of thedevice RM-147 at the ear is 0.66 W/kg.Use of device accessories and enhancements may result in different SAR values.SAR values may vary depending on national reporting and testing requirementsand the network band. Additional SAR information may be provided underproduct information at www.nokiausa.com.Your mobile device is also designed to meet the requirements for exposureto radio waves established by the Federal Communications Commission (USA)and Industry Canada. These requirements set a SAR limit of 1.6 W/kg averagedover 1 gram of tissue. The highest SAR value reported under this standard duringproduct certification for use at the ear for device type RM-147 is 0.90 W/kgand when properly worn on the body is 0.51 W/kg.
