What does "SAR" mean?
In 1996, the FCC, working with the FDA, the U.S.
Environmental Protection Agency, and other agencies,
established RF exposure safety guidelines for wireless phones
in the United States. Before a wireless phone model is
available for sale to the public, it must be tested by the
manufacturer and certified to the FCC that it does not exceed
limits established by the FCC. One of these limits is expressed
as a Specific Absorption Rate, or "SAR. " SAR is a measure of
the rate of absorption of RF energy in the body. Tests for SAR
are conducted with the phone transmitting at its highest
power level in all tested frequency bands. Since 1996, the FCC
has required that the SAR of handheld wireless phones not
exceed 1.6 watts per kilogram, averaged over one gram of
tissue.
Although the SAR is determined at the highest power level,
the actual SAR value of a wireless phone while operating can
be less than the reported SAR value. This is because the SAR
value may vary from call to call, depending on factors such as
proximity to a cell site, the proximity of the phone to the body
while in use, and the use of hands-free devices. For more
information about SARs, see the FCC's OET Bulletins 56 and
65 at http://www.fcc.gov/Bureaus/Engineering_Technology/

Industry Association website at http://www.ctia.org/

contact the manufacturer of your phone.
Can I minimize my RF exposure?
If you are concerned about RF, there are several simple steps
you can take to minimize your RF exposure. You can, of
course, reduce your talk time. You can place more distance
between your body and the source of the RF, as the exposure
level drops off dramatically with distance. The FDA/FCC
website states that "hands-free kits can be used with wireless
phones for convenience and comfort. These systems reduce
the absorption of RF energy in the head because the phone,
which is the source of the RF emissions, will not be placed
against the head. On the other hand, if the phone is mounted
against the waist or other part of the body during use, then
that part of the body will absorb more RF energy. Wireless
