RF Exposure Assessment Applicant: Microsoft Corp. Product Description: Wireless Headset FCC ID: C3K1481 RF exposure category: Portable device based upon section 2.1093 definition Assessment: Based upon KDB 447498, for portable excluded from RF routine evaluation, when the output power is below the power threshold of 60 / f( GHz), then SAR evaluation is not required. F(GHZ) is middle channel in GHz. Frequency range: FHSS: 2402 – 2482 MHz; Bluetooth: 2402‐ 2480 MHz Output power: FHSS: 1.94 mW; Bluetooth: 4.236 mW Co‐located condition: FHSS and Bluetooth radio cannot transmit simultaneously. Power Threshold for SAR exclusion: 60 / 2.42= 24.79 mW Conclusion: RF conducted output power of FHSS and Bluetooth radios are below the low power threshold thus SAR evaluation is not required.
