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),
through periodic and thorough evaluation of scientific
studies. These guidelines establish permitted levels of
radio wave exposure for the general population. All Sony
Ericsson mobile phone models are designed to operate
within these stringent levels. 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.
Therefore, the closer you are to a base station, the more
likely it is that the actual SAR level will decrease.
80 Additional information
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 phone models, all mobile phone models must be
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 is also available
on www.SonyEricssonMobile.com/.
