FCC ID LABEL: Ca. 20mm x 10mm Label Location FCC ID: 2BS43-HB2505

FCC RF Exposure EUT Description: wearable vibrator Model No.: HB2505 FCC ID: 2BS43-HB2505 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 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 2440 1.28 1±1(2) 1.585 5 0.495 3.0 Pass Note: PK Output power= conducted power. Conducted power see the test report HK2510205716-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 0.495 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
