Important information
Antenna
This phone contains a built in antenna. Use of
antenna devices not marketed by Sony Ericsson
specifically for this model could damage your
mobile phone, reduce performance, and produce
SAR levels above the established 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)
(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
not ensure compliance with FCC RF exposure
guidelines.
A separate leaflet with SAR information for this
mobile phone model is included with the material
that comes with this mobile phone. This information
can also be found, together with more information
on radio frequency exposure and SAR, on:
