■ Certification information (SAR)
This mobile device meets guidelines for exposure to radio waves
Your mobile device is a radio transmitter and receiver. It is designed not to
exceed the limits for exposure to radio waves recommended by international
guidelines. These guidelines were developed by the independent scientific
organization ICNIRP and include safety margins designed to assure the
protection of all persons, regardless of age and health.
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 0.41 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.
