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 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 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 exposure limit incorporates a substantial margin of safety to
give additional protection to the public and to account for any
variations in measurements.
