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.
