RF EXPOSURE EVALUATION FCC ID：2ACP8-NICE2 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 low channel is: 0.98dBm= 1.26mW The calculation results= 1.26/5*√2.402 =0.3906 ＜3 The maximum output power for middle channel is: 1.27dBm= 1.34mW The calculation results= 1.34/5*√2.441 =0.4186 ＜3 The maximum output power for high channel is: 1.62dBm= 1.45mW The calculation results= 1.45/5*√2.480 =0.4568 ＜3 Test Results: PASS.
