Certification information (SAR)
THIS MODEL PHONE MEETS REQUIREMENTS FOR EXPOSURE
TO RADIO WAVES
Your mobile phone is a radio transmitter and receiver. It is
designed and manufactured not to exceed the limits for
exposure to radio frequency (RF) recommended by
international guidelines (ICNIRP) These limits are part of
comprehensive 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
132
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 0.35 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
