is located near the back top edge of the iPhone. iPhone is designed and
manufactured to comply with the limits for exposure to RF energy set by the
Federal Communications Commission (FCC) of the United States, Industry
Canada (IC) of Canada, and regulating 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,

and meets the FCC, IC, and European Union RF
exposure guidelines for cellular, Wi-Fi, and Bluetooth operation. When tested
for use at the ear and for body-worn operation (with iPhone positioned
15 mm (5/8 inch) from the body), iPhone’s maximum SAR value for each
frequency band is outlined below:
Frequency Band Body Ear FCC & IC 1g SAR Limit (W/kg)
GSM 850 1.030 0.521 1.6
GSM 1900 0.522 1.290 1.6
UMTS II 1900 0.402 1.388 1.6
UMTS V 850 0.733 0.516 1. 6
Wi-Fi 0.088 0.779 1. 6
Frequency Band Body Ear EU 10g SARLimit (W/kg)
GSM 900 0.559 0.235 2.0
GSM 1800 0.369 0.780 2.0

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. 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].
