![entities of Japan, the European Union, and other countries. The exposure standard employs a unit of measurement known as the specic absorption rate, or SAR. The SAR limit applicable to iPhone set by the FCC is 1.6 watts per kilogram (W/kg), 1.6 W/kg by Industry Canada, and 2.0 W/kg by the Council of the European Union. Tests for SAR are conducted using standard operating positions (i.e., at the ear and worn on the body) specied by these agencies, with iPhone transmitting at its highest certied power level in all tested frequency bands. Although SAR is determined at the highest certied power level in each frequency band, the actual SAR level of iPhone while in operation can be well below the maximum value because iPhone adjusts its cellular transmitting power based in part on proximity to the wireless network. In general, the closer you are to a cellular base station, the lower the cellular transmitting power level.iPhone has been tested,2 and meets the FCC, IC, and European Union RF exposure guidelines for cellular, Wi-Fi, and Bluetooth operation. iPhone’s maximum SAR value for each frequency band is outlined below:Frequency Band Body3Head FCC & IC 1g SAR Limit (W/kg)GSM 850 1.11 1.00 1.6GSM 1900 0.43 1.17 1.6UMTS II 1900 0.43 1.17 1.6UMTS V 850 1.11 1.00 1.6Wi-Fi 0.07 0.88 1.6Frequency Band Body3Head EU 10g SAR Limit (W/kg)EGSM 900 0.74 0.66 2.0GSM 1800 0.28 0.59 2.0UMTS I 2100 0.36 0.93 2.0UMTS VIII 900 0.74 0.66 2.0Wi-Fi 0.05 0.36 2.0iPhone’s SAR measurement may exceed the FCC exposure guidelines for body-worn operation if positioned less than 15 mm (5/8 inch) from the body (e.g., when carrying iPhone in your pocket). 2 The device was tested by Compliance Certication Services, Fremont, CA according to measurement standards and procedures specied in FCC OET Bulletin 65, Supplement C (Edition 01-01) and IEEE P1528.1, April 21 2003, and Canada RSS 102, Issue 4, March 2010. iPhone adheres to the European Council Recommendation of 12 July 1999 on the Limitation of Exposure of the General Public to Electromagnetic Fields [1999/519/EC].3 iPhone positioned 15 mm (5/8 inch) away from the body.](https://usermanual.wiki/Apple/E2380B.08-user-guide-final/User-Guide-1300558-Page-7.png)
