Efficient use
Hold your mobile phone as you would any other phone. Do not cover the
top of the phone when it is 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 Specific
Absorption Rate (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 it is 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.
For phones sold in the US, before a phone model is available for sale to
the public, it must be tested and certified by the Federal Communications
Commission (FCC) that it does not exceed the limit established by the
government-adopted requirement for safe exposure. The tests are
performed in positions and locations (that is, at the ear and worn on the
body) as required by the FCC for each model. For body-worn operation,
this phone has been tested and meets FCC RF exposure guidelines when
the handset is positioned a minimum of 15 mm from the body without any
metal parts in the vicinity of the phone or when used with the original
