MPE CALCULATION METHOD For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] · [√ f(GHz)] ≤ 3.0 for 1-g SAR, and ≤ 7.5 for 10-g extremity SAR,30 where  f(GHz) is the RF channel transmit frequency in GHz HY-FCC RF EXPOSURE Ver.1.1 Page 5 of 6 Report No.: RF240220001-01-003 TEST RESULTS Table for Filed Antenna For BLE & BT Ant.BrandAntenna TypeConnectorGain (dBi) 1N/APCBN/A0 Frequency Conducted Peak Powert Conducted Peak Powert Operating Mode (MHz)(dBm)(mW) BLE2402-2480-2.380.58 BT2402-2480-0.610.87 Measurement Record: The minimum distance for the EUT is less than 5mm. = 9.52 mW. Since maximum peak output power of the transmitter is -0.61 dBm ≈ 0.87 mW < 9.52 mW. Hence the EUT is excluded from SAR evaluation according to FCC KDB Publication 447498 D01 General RF Exposure Guidance v06. Conclusion Result: Complies HY-FCC RF EXPOSURE Ver.1.1 Page 6 of 6 Report No.: RF240220001-01-003 Statement 1.
