Reference Information
CERTIFICATION INFORMATION (SAR)
THIS NOKIA 7270 DEVICE MEETS INTERNATIONAL GUIDELINES FOR EXPOSURE
TO RADIO WAVES.
Your mobile device is a radio transmitter and receiver. It is designed and manufactured
not to exceed the limits for exposure to radio frequency (RF) energy recommended by
international guidelines (ICNIRP). These limits establish permitted levels of RF energy
for the general population. The guidelines are based on standards that were developed
by independent scientific organizations through periodic and thorough evaluation of
scientific studies. The standards and guidelines include a substantial safety margin
designed to assure the safety of the public, regardless of age and health and to account
for any variations in measurements.
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 international guidelines is
2.0 watts/kilogram (W/kg) averaged over ten 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 well 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 when
tested according to international testing procedures for use at the ear is 0.46 W/kg.
SAR values may vary depending on national reporting and testing requirements and the
network band. Use of device accessories and enhancements may result in different SAR
values. Additional SAR information may be provided under product information at
