Radio frequency radiation exposure evaluation: portable devices 1.1 Radio Frequency Exposure Compliance 1.1.1 Electromagnetic Fields RESULT: Pass Test Specification Test item : speaker atomizing humidifier Identification / Type No. : C919 FCC ID : 2BFMK-C919 Test standard : CFR47 FCC Part 2: Section 2.1093 FCC KDB Publication 447498 D01 v06 Measurement Record: EIRP[dBm] = maximum peak output + antenna Gain = 0.42dBm + 1.3dBi =1.72dBm Since maximum peak output power of the transmitter is 1.72 dBm ≈1.49mW < 10mW. Hence the EUT is excluded from SAR evaluation according to FCC KDB Publication 447498 D01 General RF Exposure Guidance v06.
