Samsung SCH a670 User Manual

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 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 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.  

SAR tests are conducted using standard operating 
positions accepted by the FCC with the phone 
transmitting at its highest certified power level in all
