• Do not attempt to disassemble your product.
Only Sony Ericsson authorised personnel should
perform service.
• Do not direct the infrared ray at anyone's eye and make
sure that it does not disturb any other infrared units.
Antenna
Only use an antenna that has been specifically designed
by Sony Ericsson for your mobile phone. Use of
unauthorised 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).
