RF EXPOSURE EVALUATION FCC ID: 2AG68-TWS-860 According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency(RF) Radiation as specified in §1.1307(b): Routine SAR evaluation refers to that specifically required by §2.1093, using measurements or computer simulation. When routine SAR evaluation is not required, portable transmitters withoutput power greater than the applicable low threshold require SAR evaluation to qualify for TCB approval.
