Safety Human Exposure 1.1 Radio Frequency Exposure Compliance 1.1.1 Electromagnetic Fields RESULT: Pass Report No. : CN23239U 003 Test Specification Test item : DTR STITCH W KIDS HEADPHONE Identification / Type No. : HPBTSTCHPRM FCC ID : 2A2KIHPBTSTCH Test standard : CFR47 FCC Part 2: Section 2.1093 FCC KDB Publication 447498 v06 Measurement Record: The minimum distance for the EUT is less than 5mm. Since maximum peak output power of the transmitter is 5.63 dBm ≈ 3.66 mW < 3*d f = 9.52 mW. Hence the EUT is excluded from SAR evaluation according to FCC KDB Publication 447498 D01 General RF Exposure Guidance v06.
