Antenna
Only use an antenna that has been
specifically designed by Sony Ericsson for your
mobile phone. Use of unauthorised 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
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.
