RF EXPOSURE EVALUATION FCC ID：RISKAL215MIC 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 with output power greater than the applicable low threshold require SAR evaluation to qualify for TCB approval. The maximum output power for channel 1(178MHz) is: 3.96dBm= 2.49mW Tune up tolerance is: 3.50±1 dBm The Max. Tune up Power = 4.50dBm= 2.82mW The calculation results= 2.82/5*√0.178 =0.238 ＜3 The maximum output power for channel 1(198MHz) is: 3.70dBm= 2.35mW Tune up tolerance is: 3.50±1 dBm The Max. Tune up Power = 4.50dBm= 2.82mW The calculation results= 2.82/5*√0.198 =0.252 ＜3 Test Results: The product is no need to conduct SAR test.
