ANTENNA
Only use an antenna that has been specifically designed
by Sony Ericsson for your mobile phone. Use of
unauthorized 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.
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 the body without
any metal parts in the vicinity of the phone or when used
with the original Sony Ericsson body worn accessory
intended for this phone. Use of other accessories may
