80 Additional information
Only Sony Ericsson authorized personnel should perform
service.
• Do not use any accessories other than Ericsson, or Sony
Ericsson, branded originals intended for use with your
product (herinafter referred to as “original accessories”).
Use of non-original accessories may result in loss of
performance, damage to the product, fire, electric shock
or injury. The warranty does not cover product failures
which have been caused by use of non-original
accessories.
• Treat your product with care, keep it in a clean and
dust-free place.
ANTENNA CARE
Your mobile phone is equipped with an internal antenna.
• To avoid impaired performance, please ensure that your
mobile phone’s antenna is not damaged.
• Do not remove the antenna yourself.
• 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 the appropriate regulations,
causing loss of performance and SAR levels above the
recommended limits (see below).
EFFICIENT USE
For optimum performance with minimum power
consumption please:
• Hold your mobile phone as you would any other telephone.
While speaking directly into the mouthpiece, angle the
antenna in a direction up and over your shoulder.
• Do not touch the antenna when the mobile phone is in use.
Touching the antenna affects call quality, may cause the
mobile phone to operate at a higher power level than
needed and may shorten talk and standby times.
• If your mobile phone is equipped with infrared, never
direct the infrared ray at anyone’s eye and make sure
that it does not disturb any other infrared units.
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),
through periodic and thorough evaluation of scientific
studies. These guidelines establish permitted levels of
radio wave exposure for the general population. All Sony
Ericsson mobile phone models are designed to operate
within these stringent levels. 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.
