It isdesigned not to exceed the limits for exposure to radiowaves recommended by international guidelines. Theseguidelines were developed by the independent scientificorganisation ICNIRP and include safety margins designed toassure the protection of all persons, regardless of age andhealth.The exposure guidelines for mobile devices employ a unit ofmeasurement known as the Specific Absorption Rate orSAR. The SAR limit stated in the ICNIRP guidelines is 2.0watts/kilogram (W/kg) averaged over 10 grams of tissue.Tests for SAR are conducted using standard operatingpositions with the device transmitting at its highestcertified power level in all tested frequency bands. Theactual SAR level of an operating device can be below themaximum value because the device is designed to use onlythe power required to reach the network. That amountchanges depending on a number of factors such as how
