ANTENNA
Only use an antenna that has been specifically designed
by Sony Ericsson for your mobile phone. Use of
unauthorised or modified antennas could damage your
mobile phone and may violate regulations, causing loss
of performance and SAR levels above the recommended
limits (see below).
EFFICIENT USE
Hold your mobile phone as you would any other 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 than needed, thus shortening talk
and standby times.
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), through periodic and thorough evaluation of
scientific studies. These guidelines establish permitted
levels of radio wave exposure for the general population.
All Sony Ericsson mobile phone models are designed to
operate within these stringent levels. 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.
Therefore, the closer you are to a base station, the more
likely it is that the actual SAR level will decrease.
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
various 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 www.SonyEricsson.com/.
