guidelines and establish permitted levels of RF
energy for the general population. The guidelines
were developed by independent scientific
organisations through periodic and thorough
evaluation of scientific studies. The guidelines
include a substantial safety margin designed to
assure 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 stated in the
international guidelines is 2.0 W/kg*. Tests for SAR
are conducted using standard operating positions
with the 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 of the phone while
operating can be well below the maximum value.
This is because the 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 base station, the lower the power
output of the phone.
The highest SAR value for this model phone when
tested for use at the ear is 0.82 W/kg. While there
may be differences between the SAR levels of
various phones and at various positions, they all
meet the relevant international guidelines for RF
exposure.
* The SAR limit for mobile phones used by the public
is 2.0 watts/kilogram (W/kg) averaged over ten
grams of body tissue. The guidelines incorporate a
substantial margin of safety to give additional
protection for the public and to account for any
variations in measurements. SAR values may vary
depending on national reporting requirements and
the network band. For SAR information in other
regions please look under product information at
