Radio waves ..............................
THIS MOBILE PHONE MEETS THE GOVERNMENT’S
REQUIREMENTS FOR EXPOSURE TO RADIO WAVES.
Your mobile phone is a radio transmitter and receiver. It is designed
and manufactured not to exceed the emission limits for exposure to
radio-frequency (RF) energy. These limits are part of comprehensive
guidelines and establish permitted levels of RF energy for the
general population. The guidelines are based on standards that were
developed by independent scientific organizations through periodic
and thorough evaluation of scientific studies. These guidelines include
a substantial safety margin designed to ensure the safety of all
persons, regardless of age and health.
The exposure standard for mobile phones employs a unit of
measurement known as the Specific Absorption Rate, or SAR. The SAR
limit set by public authorities such as the Federal Communications
Commission of the US Government (FCC), or by Industry Canada,
is 1.6 W/kg averaged over 1 gram of body tissue. Tests for SAR
are conducted using standard operating positions with the mobile
phone transmitting at its highest certified power level in all tested
frequency bands.
Although the SAR is determined at the highest certified power level,
the actual SAR level of the mobile phone while operating can be
well below the maximum value. This is because the mobile phone is
designed to operate at multiple power levels so as to use only the
power required to reach the network. In general, the closer you are
to a wireless base station antenna, the lower the power output of
the mobile phone. Before a mobile phone model is available for sale
to the public, compliance with national regulations and standards
must be shown.
The highest SAR value for this model mobile phone when tested is
0.97 W/Kg for use at the ear and 1.31 W/Kg for use close to the body.
While there may be differences between the SAR levels of various
mobile phones and at various positions, they all meet the government
requirement for RF exposure. For body-worn operation, the mobile
phone meets FCC RF exposure guidelines provided that it is used
with a non-metallic accessory with the handset at least 10 mm from
the body. Use of other accessories may not ensure compliance with
FCC RF exposure guidelines.
