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
required by the FCC for each model. For body-worn
operation, this phone has been tested and meets
