Efficient Use - Sony Ericsson Z710i User Manual

Emergency calls may not be possible in all areas,
on all cellular networks, or when certain network
services and/or mobile phone features are in use.
Check with your local network operator.
Antenna
This phone contains a in-built antenna. Use of
antenna devices not marketed by Sony Ericsson
specifically for this model could damage your
mobile phone, reduce performance, and produce
SAR levels above the established limits (see below).

Efficient use

Hold your mobile phone as you would any other
phone. Do not cover the top of the phone when it is
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 stand-by times.
Radio frequency (RF) exposure and
Specific Absorption Rate (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
it is 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.
For phones sold in the US, before a phone model
is available for sale to the public, it must be tested
and certified by the Federal Communications
Commission (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 15 mm from the body
without any metal parts in the vicinity of the phone
or when used with the original Sony Ericsson
accessory intended for this phone and worn on
the body. Use of other accessories may not ensure
compliance with FCC RF exposure guidelines.
A separate leaflet with SAR information about this
mobile phone model is included with the material
accompanying this mobile phone. This information
can also be found, together with more information
on radio frequency exposure and SAR, on:
