• •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
