These FCC exposure limits are derived from the recommendations of two expert
organizations, the National Counsel on Radiation Protection and Measurement
(NCRP) and the Institute of Electrical and Electronics Engineers (IEEE). In both cases,
the recommendations were developed by scientific and engineering experts drawn
from industry, government, and academia after extensive reviews of the scientific
literature related to the biological effects of RF energy.
The exposure limit set by the FCC for wireless mobile phones employs a unit of
measurement known as the Specific Absorption Rate (SAR). The SAR is a measure of
the rate of absorption of RF energy by the human body expressed in units of watts
per kilogram (W/kg). The FCC requires wireless phones to comply with a safety limit
of 1.6 watts per kilogram (1.6 W/kg). The FCC exposure limit incorporates a
substantial margin of safety to give additional protection to the public and to account
for any variations in measurements.
SAR tests are conducted using standard operating positions accepted by the FCC
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 level 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
wireless base station antenna, the lower the power output.
Before a new model phone is available for sale to the public, it must be tested and
certified to the FCC that it does not exceed the exposure limit established by the
FCC. Tests for each model phone are performed in positions and locations (e.g. at
the ear and worn on the body) as required by the FCC. For body worn operation, this
phone has been tested and meets FCC RF exposure guidelines when used with an
accessory that contains no metal and that positions the handset a minimum of
1.5 cm from the body. Use of other accessories may not ensure compliance with FCC
RF exposure guidelines.
The FCC has granted an Equipment Authorization for this mobile phone with all
reported SAR levels evaluated as in compliance with the FCC RF exposure
guidelines. The maximum SAR values for this model phone as reported to the FCC
are:
850 Head - 0.516 W/Kg
Body - 0.507 W/Kg
1900 Head - 0.962 W/Kg
Body - 0.433 W/Kg
