FCC RF Exposure EUT Description: TWS Wireless Earphones Model No.: Q66 1. Limits According to KDB 447498 D01 General RF Exposure Guidance v06 The 1‐g and 10‐g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤50 mm are determined by: [(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, Where: Result=P/D*√F F= the RF channel transmit frequency in GHz P=Maximum turn‐up power in mw D=Min. test separation distance in mm 2. Test Result of RF Exposure Evaluation 2.4G Output power （dBm ） Tune Up Power （dBm） Max Tune Up power dBm/mW Min test separatio n distance mm Result Limit SAR Test Exclusion EDR ‐11.71 ‐12±1 ‐11/0.08 5 0.0248 3.0 Pass Note: PK Output power= conducted power. Conducted power see the test report HK2012314054‐E, antenna gain=0dBi Per KDB 447498 D01, when the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine RF Exposure test exclusion. The test exclusion threshold is 0.0248 which is<= 3, RF Exposure testing is not required. Note: Exclusion Thresholds Results=[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] f(GHz) is the RF channel transmit frequency in GHz Distance=5mm
