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.
