Exposure to Radio Frequency (RF) Signals
Certification Information (SAR)
This product can contain an embedded radio transmitter and
receiver. It is designed and manufactured not to exceed the
exposure limits for radio frequency (RF) energy set by the Federal
Communications Commission (FCC) of the U.S. government. These
FCC exposure limits are derived from the recommendations of two
expert organizations, the National Council 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 devices 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 devices 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 wireless 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 device while operating can be well below the
maximum value. This is because the device 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 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 are
performed in positions and locations (e.g. at the bottom on the
body) as required by the FCC.
For body worn operation, this model has been tested and meets
the FCC RF exposure guidelines when used with Samsung
accessory designated for this product. Non-compliance with
the above restrictions may result in violation of FCC RF exposure
guidelines.
SAR information on this and other model can be viewed on-line at
http://www.fcc.gov/oet/ea/fccid/. This site uses this product FCC
ID number on the outside of the product. Sometimes it may be
necessary to remove the battery pack to find the number. Once
you have the FCC ID number for a particular product, follow the
instructions on the website and it should provide values for typical
or maximum SAR for a particular product.
