Important information
Efficient use
Hold your mobile 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 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 it
is 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 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 FCC RF
exposure guidelines when the handset is positioned
a minimum of 15 mm from the body without any
metal parts in the vicinity of the phone or when
used with the original Sony Ericsson accessory
intended for this phone and worn on the body. Use
of other accessories may not ensure compliance
with FCC RF exposure guidelines.
A separate leaflet with SAR information about this
mobile phone model is included with the material
accompanying this mobile phone. This information
can also be found, together with more information
on radio frequency exposure and SAR, at
.
Accessible Solutions/Special Needs
For phones sold in the US, you can use your TTY
terminal with your Sony Ericsson mobile phone
(with the necessary accessory). For information
on Accessible Solutions for individuals with special
needs call the Sony Ericsson Special Needs Center
on 877 878 1996 (TTY) or 877 207 2056 (voice), or
visit the Sony Ericsson Special Needs Center at
