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:
