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.
