Additional information
Efficient use
Hold your mobile phone as you would any othe
r
phone. Do not cover the top of the phone when
in use, as this affects call quality and may cause
the phone to operate at a higher power level tha
n
needed, thus shortening talk and standby times.
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 low l
evels
of radio frequency energy (also known as radio wav
es
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 Electric
al and
Electronics Engineers Inc.) through periodic and
thorough evaluation of scientific studies. Thes
e
guidelines establish permitted levels of radio wav
e
exposure for the general population. The levels includ
e
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 mobi
le
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 ex
posure
guidelines do not mean that there are variations i
n
safety. While there may be differences in SA
R levels
among mobile phones, all Sony Ericsson mobil
e
phone models are designed to meet radio frequenc
y
exposure guidelines.
Before a phone model is available for sale to the pub
lic,
it must be tested and certified to the FCC that it does
not exceed the limit established by the governm
ent-
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 f
or
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 v
icinity of
the phone or when used with the original Sony Ericsson
body worn accessory intended for this phone. U
se of
other accessories may not ensure compliance wi
th
FCC RF exposure guidelines.
A separate leaflet with SAR information for thi
s mobile
phone model is included with the material that c
omes
with this mobile phone. This information can also be
found, together with more information on r
adio
frequency exposure and SAR,
