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.
Before a phone model is available for sale to the
public, it must be tested and certified to the FCC that
it does not exceed the limit established by the
government-adopted requirement for safe exposure.
The tests are performed in positions and locations
(that is, at the ear and worn on the body) as required
by the FCC for each model. For body worn operation,
this phone has been tested and meets FCC RF
exposure guidelines when the handset is positioned
a minimum of 15 mm from the body without any metal
parts in the vicinity of the phone or when used with
the original Sony Ericsson body worn accessory
intended for this phone. Use of other accessories
may not ensure compliance with FCC RF 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.
