FCC RF Exposure EUT Description: MD750 Delight Model No.: MD750 Delight FCC ID: 2AURQ-MD750 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 Frequency (MHz) Output power (dBm) Tune Up Power (dBm) Max Tune Up power (dBm/mW) Min test separation distance (mm) ResultLimit (mW/cm 2 ) SAR Test Exclusion 2440 2.77 2±1(3) 1.995 5 0.6233.0 Pass Note: PK Output power= conducted power. Conducted power see the test report HK2406213273-E, antenna gain=2.94dBi 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 0.623 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
