AND SAR
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.
While in data transfer, the mobile phone is not
designed to be held next to the ear.
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.
Before a phone model is available for sale to the
public, it must be tested and certified to the 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
