The guidelines were developed byindependent scientific organisations through periodic and thorough evaluation of scientificstudies. The guidelines include a substantial safety margin designed to assure the safety ofall persons, regardless of age and health.The exposure standard for mobile devices employs a unit of measurement known as theSpecific Absorption Rate, or SAR. The SAR limit stated in the international guidelines is2.0 W/kg*. Tests for SAR are conducted using standard operating positions with the devicetransmitting at its highest certified power level in all tested frequency bands. Although theSAR is determined at the highest certified power level, the actual SAR of the device whileoperating can be 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 to reach the network.In general, the closer you are to a base station, the lower the power output of the device.The highest SAR value for this device when tested for use at the ear is 0.67 W/kg.This device meets RF exposure guidelines when used either in the normal use positionagainst the ear or when positioned at least 1.5 cm away from the body. When a carry case,belt clip or holder is used for body-worn operation, it should not contain metal and shouldposition the product at least 1.5 cm away from your body.In order to transmit data files or messages, this device requires a quality connection to thenetwork. In some cases, transmission of data files or messages may be delayed until such aconnection is available. Ensure the above separation distance instructions are followed untilthe transmission is completed.* The SAR limit for mobile devices used by the public is 2.0 watts/kilogram (W/kg) averagedover ten grams of body tissue. The guidelines incorporate a substantial margin of safety togive additional protection for the public and to account for any variations in measurements.SAR values may vary depending on national reporting requirements and the network band.For SAR information in other regions please look under product information atwww.nokia.com.
