Emergency calls
Mobile phones operate using radio signals, which cannot guarantee
connection in all conditions. You should therefore never rely solely upon
any mobile phone for essential communications (e.g. medical
emergencies).
Emergency calls may not be possible in all areas, on all cellular networks,
or when certain network services and/or mobile phone features are in use.
Check with your local service provider.
Antenna
This phone contains a built-in antenna. Use of antenna devices not
marketed by Sony Ericsson specifically for this model could damage your
mobile phone, reduce performance, and produce SAR levels above the
established limits (see below).
Efficient use
Hold your mobile phone as you would any other phone. Do not cover the
top of the phone when it is 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 Specific
Absorption Rate (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.
