FCC RF Exposure EUT Description: Silicone Wireless Mouse Model No.: SME12 FCC ID: 2BBRL‐SME12 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 2477MHz: EIRP(dBm)=101.57(dBuV/m)-95.3=6.27(dBm) Frequency (MHz) Output power (dBm) Tune Up Power (dBm) Max Tune Up power dBm/mW Min test separatio n distance mm Result Limit (mW/cm 2 ) SAR Test Exclusion 2477 6.27 6±1 7/5.01 5 1.57759 3.0 Pass Note: PK Output power= conducted power. Conducted power see the test report HK2306052295‐E, antenna gain=2.34dBi 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 1.57759 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

Measurements in both horizontal and vertical polarities were performed. During the test, each emission was maximized by: having the EUT continuously working, investigated all operating modes, rotated about all 3 axis (X, Y & Z) and considered typical configuration to obtain worst position, manipulating interconnecting cables, rotating the turntable, varying antenna height from 1m to 4m in both horizontal and vertical polarizations.
