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 for wireless
mobile phones employs a unit
of measurement known as the
Specific Absorption Rate, or 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.
Tests for SAR are conducted using
standard operating positions
specified by the FCC with the
phone transmitting at its highest
certified power level in all tested
frequency bands. Although 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.
Because the phone is designed to
operate at multiple power levels
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 phone model is available
for sale to the public, it must
be tested and certified to the
FCC that it does not exceed
the limit established by the
governmentadopted requirement
for safe exposure. The tests
are performed in positions and
locations (e.g., at the ear and worn
on the body) as required by the
FCC for each model.
This device was tested for typical
body-worn operations with the
back of the phone kept 0.78
inches (2.0 cm) between the
user’s body and the back of the
phone. To comply with FCC RF
exposure requirements, a minimum
separation distance of 0.78 inches
(2.0 cm) must be maintained
between the user s body and the
