Efficient Use - Sony Ericsson Walkman W600 User Manual

Important Information
• Do not place your product or install wireless
equipment in the area above your car's air bag.
• Do not attempt to disassemble your
product. Only Sony Ericsson authorized
personnel should perform service.
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.
For phones sold in the U.S., 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
