• Do not use your product when in, or around aircraft,
or areas posted “turn off two-way radio”.
• Do not use your product in an area where
a potentially explosive atmosphere exists.
• Do not place your product or install
wireless equipment in the area above
your car’s air bag.
• Do not attempt to disassemble your
product. Only Sony Ericsson authorised
personnel should perform service.
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) 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
