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),
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.
Accessories can significantly affect a mobile phone's
compliance with the radio frequency exposure guidelines.
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 the mobile phone is positioned a
minimum of 1.5 cm (0.6 in.) from your body and that you
are not using an accessory that contains any metal.
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
