Nokia 1661 Guia Del Usuario página 34

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 1.38 W/kg (RH-122) or 0.91 W/kg (RH-121).
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. Additional
SAR information may be provided under product
information at www.nokia.com.
