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.
