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.
A separate leaflet with SAR information for this mobile phone model
is included with the material that comes with this mobile phone. This
information can also be found, together with more information on
radio frequency exposure and SAR, on: www.sonyericsson.com/cn.
