RADIO FREQUENCY (RF) EXPOSURE
AND SAR
Your mobile phone is a low-power radio transmitter and
receiver. When it is turned on, it emits low levels of radio
frequency energy (also known as radio waves or radio
frequency fields).
Governments around the world have adopted
comprehensive international safety guidelines,
developed by scientific organizations, e.g. ICNIRP
(International Commission on Non-Ionizing Radiation
Protection) and IEEE (The Institute of Electrical and
Electronics Engineers Inc.), through periodic and
thorough evaluation of scientific studies. These
guidelines establish permitted levels of radio wave
exposure for the general population.
The levels include a safety margin designed to assure
the safety of all persons, regardless of age and health,
and to account for any variations in measurements.
Specific Absorption Rate (SAR) is the unit of
measurement for the amount of radio frequency
energy absorbed by the body when using a mobile
phone. The SAR value is determined at the highest
certified power level in laboratory conditions, but the
actual SAR level of the mobile phone while operating
can be well below this value. This is because the

mobile phone is designed to use the minimum power
required to reach the network.
Variations in SAR below the radio frequency exposure
guidelines do not mean that there are variations in safety.
While there may be differences in SAR levels among
mobile phones, all Sony Ericsson mobile phone models
are designed to meet radio frequency exposure
guidelines.
For residents in countries that have adopted the
SAR limit recommended by the International
Commisssion on Non-Ionizing Radiation Protection
(ICNIRP), the highest SAR value for this model phone
when tested by Sony Ericsson for use at the ear is
0.88 W/kg averaged over ten (10) grams of tissue.
DRIVING
Please check if local laws and regulations restrict the
use of mobile phones while driving or require drivers to
use handsfree solutions. We recommend that you use
only Ericsson or Sony Ericsson handsfree solutions
intended for use with your product. Please note that
because of possible interference to electronic equipment,
some vehicle manufacturers forbid the use of mobile
phones in their vehicles unless a handsfree kit with
an external antenna supports the installation.
Always give full attention to driving and pull off the road
and park before making or answering a call if driving
conditions so require.
