Guidelines for safe and efficient use 173
Preliminary
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. Therefore, the closer you are to a base station, the
more likely it is that the actual SAR level will decrease.
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.
Accessories can significantly affect a mobile phone's
compliance with the radio frequency exposure guidelines. For
example, the Federal Communication Commission in the U.S.
requires that some manufacturers' accessories shall be tested,
and Sony Ericsson has done so with respect to its products. To
avoid causing loss of performance or radio frequency exposure
levels above the permissible limits it is recommended that you
only use Sony Ericsson or Ericsson original accessories
intended for use with the mobile phone. If you wear the mobile
phone on your body while it is transmitting, and you do not use
a Sony Ericsson or Ericsson original body worn accessory,
please ensure that you are not using an accessory that contain
any metal.
A separate leaflet with SAR information for this mobile phone
model is included with the material that comes with this mobile
phone. This information can also be found, together with more
information on radio frequency exposure and SAR, on
www.sonyericsson.com/.
Driving
Please check if local laws/regulations restrict the use of mobile
phones while driving or require drivers to use handsfree
solutions. We recommend that you use only Ericsson or Sony
Ericsson handsfree solutions intended for use with your product.
