Additional Information
• Do not attempt to disassemble your
product. Only Sony Ericsson authorized
personnel should perform service.
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
