Operation Manual

Exposure to Radio Frequency Energy
iPhone contains radio transmitters and receivers. When on, iPhone receives and sends
out radio frequency (RF) energy through its antenna. The iPhone antenna is located on
the back of iPhone near the dock connector. iPhone is designed and manufactured not
to exceed limits for exposure to RF energy set by the Federal Communications
Commission (FCC) of the United States and the recommendations of the Council of the
European Union. The exposure standard employs a unit of measurement known as the
specific absorption rate, or SAR. The SAR limit applicable to iPhone set by the FCC is 1.6
watts per kilogram (W/kg). The SAR limit applicable to iPhone set by the Council of the
European Union is 2.0 W/kg. Tests for SAR are conducted using standard operating
positions (i.e., at the ear and worn on the body) specified by the FCC and the Council of
the European Union, with iPhone transmitting at its highest certified power level in all
tested frequency bands. Although SAR is determined at the highest certified power
level, 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 and European Union RF exposure
guidelines for cellular, Wi-Fi, and Bluetooth® operation. When tested for use at the ear,
iPhone’s highest SAR value is 0.974 W/kg. When tested for body-worn operation, with
iPhone positioned 15 mm (5/8 inch) from the body, iPhone’s highest SAR value is 0.694
W/kg. For body-worn operation, iPhone’s SAR measurement may exceed the FCC
exposure guidelines if positioned less than 15 mm (5/8 inch) from the body. For optimal
mobile device performance and to be sure that human exposure to RF energy does not
exceed the FCC and European Union guidelines, always follow these instructions and
precautions: When on a call using the built-in audio receiver in iPhone, hold iPhone
with the 30-pin connector pointed down toward your shoulder to increase separation
from the antenna. For body-worn operation, keep iPhone at least 15 mm (5/8 inch)
away from the body, and only use carrying cases, belt clips, or holders that do not have
metal parts and that maintain at least 15 mm (5/8 inch) separation between iPhone
and the body. When using the cellular network data transmission feature of iPhone (see
page 24 for more information), position iPhone’s antenna at least 15 mm (5/8 inch)
from the body.
If you are still concerned about exposure to RF energy, you can further limit your
exposure by limiting the amount of time using iPhone, since time is a factor in how
much exposure a person receives, and by placing more distance between your body
and iPhone, since exposure level drops off dramatically with distance.

The device was tested by an accredited laboratory according to measurement standards and procedures specified in
FCC OET Bulletin 65, Supplement C (Edition 01-01) and IEEE P1528.1, April 21 2003. 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].
