Specific Absorption Rate (SAR)
Certification Information
Your wireless phone is a 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 RF 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 RF 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 SAR 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 reported 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 of the phone.
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 SAR 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 mobile device a
minimum of 1.0 cm from the body.
