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 fre
quency fields).
Governments around the world have adopted comprehensive international safety guide
lines, 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, regard
less 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 fre
quency 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.
