• 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 antenna portion 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. The antenna portion is located at the bottom of the keypad. When the phone is open, the antenna is at the bottom of the phone. When the phone is closed, it is at the top of the phone. Additional information 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. This is the Internet version of the user's guide. © Print only for private use. 81

Additional 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 antenna portion of the phone
when in use, as this affects call quality and m
ay
cause the phone to operate at a higher power level
than needed, thus shortening talk and standby times.
The antenna portion is located at the bottom of the
keypad. When the phone is open, the antenna is at
the bottom of the phone. When the phone is closed, it
is at the top of the phone.
Radio frequency (RF) exposure
and SAR
Your mobile phone is a low-power radio transm
itter
and receiver. When it is turned on, it emits low leve
ls
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

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
