Important Information
• Do not place your product or install wireless 
equipment in the area above your car's air bag.
• 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.
For phones sold in the U.S., 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
