89 Important information
Driving
Please check if local laws and regulations restrict
the use of mobile phones while driving or require
drivers to use handsfree solutions. We recommend
that you use only Sony Ericsson handsfree
solutions intended for use with your product.
Please note that because of possible interference
to electronic equipment, some vehicle
manufacturers forbid the use of mobile phones
in their vehicles unless a handsfree kit with an
external antenna supports the installation.
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.
Variations in SAR below the radio frequency
exposure guidelines do not mean that there are
variations in safety. While there may be differences
in SAR levels among mobile phones, all Sony
Ericsson mobile phone models are designed to
meet radio frequency exposure guidelines.
For phones sold in the U.S., before a phone model
is available for sale to the public, it must be tested
and certified to the FCC that it does not exceed the
limit established by the government-adopted
requirement for safe exposure. The tests are
performed in positions and locations (that is, at the
ear and worn on the body) as required by the FCC
