Safe and Efficient Use 71
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 various mobile phones, all Sony
Ericsson mobile phone models are designed to meet
the relevant guidelines for radio frequency exposure.
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 of
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 on your body while it is transmitting, and
you do not use a Sony Ericsson or Ericsson original
body worn accessory, please ensure that the mobile
phone is positioned a minimum of 1.5 cm from your
body and 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
