Guidelines for Safe and Efficient Use
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.If your mobile
phone is equipped with an retractable antenna, Sony
Ericsson recommends that the antenna should be
kept fully retracted (closed) while the phone is in use
and worn on the body to avoid the antenna
touching, or coming in close proximity to, the body.
Do not use the mobile phone with the front and/or
back cover removed from the unit.
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. Therefore, the closer you are to a base station,
