62 Guidelines for safe and efficient use
• Do not use any accessories other than Ericsson or
Sony Ericsson originals compatible with the Product
(see “Accessory information” on page 69). Use of
other 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 the use of non-Sony Ericsson
approved accessories as specified above.
• Treat your product with care, keep it in a clean
and dust-free place.
ANTENNA CARE
Do not attempt to remove the antenna yourself. If your
mobile phone’s antenna is damaged, please take it to
an Sony Ericsson service partner.
Only use the supplied antenna. Use of
unauthorised antennas, modifications, or attachments
could damage the mobile phone and may violate the
appropriate regulations, causing loss of performance
and SAR levels above the recommended limits (see
below).
EFFICIENT USE
Only expose the mobile phone to temperatures
between +55°C (+131°F) and -10°C (+14°F) when
the mobile phone is in use.
For optimum performance with minimum power
consumption please:
• Hold the mobile phone as you would any other
telephone.
• 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 an infrared eye,
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
ANDSAR
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 organisations, 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
