FCC RF Exposure EUT Description: DISCO BALL WIRELESS LED SPEAKER Model No.: PY‐LDBS‐SLV FCC ID: 2BBPLPYLDBS 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 separati on distance mm Result Limit (mW/cm 2 ) SAR Test Exclusion 2480 0.77 0±1 1/1.259 5 0.397 3.0 Pass Note: PK Output power= conducted power. Conducted power see the test report HK2307213200‐E, antenna gain= ‐0.58dBi 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 0.397 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
