Nokia 5230 User Manual page 159

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 organisation 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 1.10 W/kg.
Use of device accessories may result in different SAR values. SAR values may vary
depending on national reporting and testing requirements and the network band.
