FCC RF Exposure EUT Description: XX LED RGB STRIP Model No.: XX5050RGB-60D FCC ID: 2A855-5050RGB-60D 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)]ꞏ[√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 EIRP(dBm)=77.09(dBuV/m)-95.2=-18.11(dBm) Frequency (MHz) Output power (dBm) Tune Up Power (dBm) Max Tune Up power (mW) Min test separati on distance mm Result Limit SAR Test Exclusion 433.971 -18.11 -18±1(-17) 0.020 5 0.003 3.0 Pass Note: PK Output power= conducted power. Conducted power see the test report HK2510315925-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 SAR test exclusion. The test exclusion threshold is 0.003 which is<= 3, SAR testing is not required. Note: Exclusion Thresholds Results=[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ꞏ[√f(GHz)] f(GHz) is the RF channel transmit frequency in GHz Distance=5mm
