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
