70 Important information
Driving
Please check if local laws and regulations restrict
the use of 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 phones in their vehicles unless
a handsfree kit with an external antenna has been
installed.
Always pay full attention to driving and pull off the
road and park before making or answering a call if
driving conditions so require.
Emergency calls
Phones operate using radio signals, which cannot
guarantee connection in all conditions. You should
therefore never rely solely upon any phone for
essential communications (for example, medical
emergencies).
Emergency calls may not be possible in all areas,
on all cellular networks, or when certain network
services and/or 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
phone, reduce performance, and produce SAR
levels above the established limits (see below).
Efficient use
Hold your 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 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, for example,
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 phone.
The SAR value is determined at the highest certified
power level in laboratory conditions, but the actual
SAR level of the phone while it is operating can be
well below this value. This is because the 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 phones, all Sony Ericsson
phone models are designed to meet radio frequency
exposure guidelines.
For phones sold in the US, before a phone model is
available for sale to the public, it must be tested and
certified by the Federal Communications Commission
(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
