ANTENNA
Only use an antenna that has been specifically designed
by Sony Ericsson for your mobile phone. Use of
unauthorized or modified antennas could damage your
mobile phone and may violate regulations, causing loss
of performance and SAR levels above the recommended
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.
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
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 20 mm from the body without any metal parts
in the vicinity of the phone or when used with the original
Sony Ericsson body worn accessory intended for this phone.
Use of other accessories may not ensure compliance with
FCC RF exposure guidelines.
