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 mobile phones, all Sony Ericsson mobile phone
models are designed to meet radio frequency exposure guidelines.
