Certification information (SAR)
THIS 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) recommended by
international guidelines (ICNIRP). These limits are part of
comprehensive guidelines and establish permitted levels of RF
energy for the general population. The guidelines were
developed by independent scientific organizations through
periodic and thorough evaluation of scientific studies.
The guidelines include a substantial safety margin designed
to assure the safety of all persons, regardless of age and
health.
The exposure standard for mobile devices employs 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)*. Tests for SAR are conducted
using standard operating positions with the device
transmitting at its highest certified power level in all tested
frequency bands. Although the SAR is determined at the
highest certified power level, the actual SAR of the device
while operating can be well below the maximum value. This is
because the device is designed to operate at multiple power
levels so as to use only the power required to reach the
network. In general, the closer you are to a base station, the
lower the power output of the device.

The highest SAR value for this device when tested for use at
the ear is 0.68 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 www.nokia.com.
* The SAR limit for mobile devices used by the public is
2.0 W/kg averaged over 10 grams of body tissue.
The guidelines incorporate a substantial margin of safety to
give additional protection for the public and to account for
any variations in measurements. SAR values may vary
depending on national reporting requirements and the
network band. For SAR information in other regions,
please look under product information at www.nokia.com.
