Guidelines for Safe and Efficient Use
• Do not touch the antenna when the mobile phone is in use.
Touching the antenna affects call quality, may cause the mobile
phone to operate at a higher power level than needed and may
shorten talk and standby times.
• Do not use the mobile phone when the front and/or back cover
is removed from the unit.
• If your mobile phone is equipped with infrared, never direct
the infrared ray at anyone’s eye and make sure that it does not
disturb any other infrared units.
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), through periodic and thorough
evaluation of scientific studies. These guidelines establish permitted
levels of radio wave exposure for the general population. All Sony
Ericsson mobile phone models are designed to operate within these
stringent levels. 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
phone while operating can be well below this value.
This is because the 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 phone models, all mobile
phone models must be designed to meet radio frequency exposure
guidelines.
Accessories can significantly affect SAR compliance. 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. Sony Ericsson has not tested
non-original accessories in conjunction with Sony Ericsson mobile
phones. It is therefore recommended that only original accessories
are used in conjunction with Sony Ericsson mobile phones.
