Radio frequency (RF), radio wave exposure and Specific
Absorption Rate (SAR) information
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
