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/.
DRIVING
Please check if local laws and regulations restrict the use
of mobile phones while driving or require drivers to use
handsfree solutions. We recommend that you use only
Ericsson or Sony Ericsson handsfree solutions intended
for use with your product. Please note that because of
possible interference to electronic equipment, some
vehicle manufacturers forbid the use of mobile phones
in their vehicles unless a handsfree kit with an external
antenna supports the installation.
