The exposure guidelines for mobile devices employ a unit of
measurement known as the Specific Absorption Rate or SAR. The
SAR limit stated in the ICNIRP guidelines is 2.0 watts/kilogram
(W/kg) averaged over 10 grams of tissue. Tests for SAR are
conducted using standard operating positions with the device
transmitting at its highest certified power level in all tested
frequency bands. The actual SAR level of an operating device can
be below the maximum value because the device is designed to
use only the power required to reach the network. That amount
changes depending on a number of factors such as how close you
are to a network base station. The highest SAR value under the
ICNIRP guidelines for use of the device at the ear is 0.76 W/kg.
Use of device accessories and enhancements may result in
different SAR values. SAR values may vary depending on national
reporting and testing requirements and the network band.
Additional SAR information may be provided under product
information at www.nokia.com.
Your mobile device is also designed to meet the requirements for
exposure to radio waves established by the Federal
Communications Commission (USA) and Industry Canada. These
requirements set a SAR limit of 1.6 W/kg averaged over one gram
of tissue. The highest SAR value reported under this standard
during product certification for use at the ear is 1.12 W/kg and
when properly worn on the body is 0.55 W/kg.
