Reference Information
CERTIFICATION INFORMATION (SAR)
THIS MODEL 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 limits for exposure to radio frequency (RF) energy set by Industry Canada. 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 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 set by the Industry Canada is 1.6 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.
Before a phone model is available for sale to the public, compliance with the Canadian
Standard must be shown. The highest SAR value for the Nokia 6820a model phone as
reported to the FCC when tested for use at the ear is 0.66 W/kg, and when worn on the body,
as described in this user guide, is 1.20 W/kg. The highest SAR value for the Nokia 6820b
model phone as reported to the FCC when tested for use at the ear is 0.78 W/kg, and when
worn on the body, as described in this user guide, is 0.87 W/kg.
(Body-worn measurements differ among phone models, depending upon available
enhancements and Industry Canada requirements).
While there may be differences between the SAR levels of various phones and at various
positions, they all meet the government requirement for RF exposure.
* The SAR limit for mobile phones used by the public is 1.6 watts/kilogram (W/kg) averaged
over one gram of body tissue. The standard incorporates 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
