Important Information
Always give full attention to driving and pull off the
road and park before making or answering a call if
driving conditions so require.
Emergency calls
Mobile phones operate using radio signals, which
cannot guarantee connection under all conditions.
Therefore you should 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 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).
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.
Specific Absorption Rate (SAR) is the unit of
measurement for the amount of radio frequency
energy absorbed by the body when using a mobile
phone. The SAR value is determined at the highest
certified power level in laboratory conditions, but the
actual SAR level of the mobile phone while operating
can be well below this value. This is because the
mobile phone is designed to use the minimum power
required to reach the network.
