Additional information
Radio frequency (RF) exposure
and SAR
Your mobile phone is a low-power radio transm
itter
and receiver. When it is turned on, it emits lo
w levels
of radio frequency energy (also known as radio waves
or radio frequency fields).
Governments around the world have adopted
comprehensive international safety guideli
nes,
developed by scientific organizations, e.g. ICNIRP
(International Commission on Non-Ionizing Radi
ation
Protection) and IEEE (The institute of Electrical and
Electronics Engineers Inc.), through periodic an
d
thorough evaluation of scientific studies. These
guidelines establish permitted levels of radio wave
exposure for the general population. All Sony Eri
csson
mobile phone models are designed to operate within
these stringent levels. The levels include a safety m
argin
designed to assure the safety of all persons, rega
rdless
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 frequen
cy energy
absorbed by the body when using a mobile phone.
The SAR value is determined at the highest cert
ified
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 design
ed to use
the minimum power required to reach the ne
twork.
Therefore, the closer you are to a base station, the
more likely it is that the actual SAR level will decrea
se.
Variations in SAR below the radio frequency exp
osure
guidelines do not mean that there are variation
s in
safety. While there may be differences in SAR leve
ls
among mobile phones, all Sony Ericsson mobile p
hone
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 do
es
not exceed the limit established by the governmen
t-
adopted requirement for safe exposure. The tes
ts are
performed in positions and locations (that is, at the e
ar
and worn on the body) as required by the FCC for
each
model. For body worn operation, this phone ha
s 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 vicin
ity 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 mo
bile
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
