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.
