FCC RF Exposure EUT Description: Wireless Mouse Model No.: M1 FCC ID: 2A6LZ-M1 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 SRD EIRP(dBm)=99.62(dBuV/m)-95.2=4.42(dBm) Frequency (MHz) Output power (dBm) Tune Up Power (dBm) Max Tune Up power (mW) Min test separation distance mm Result Limit SAR Test Exclusion BLE 2402 -0.50 -1±1(0) 1.000 5 0.310 3.0 Pass SRD 2480 4.42 4±1(5) 3.162 5 0.996 3.0 Pass Note: PK Output power= conducted power. Conducted power see the test report HK2506093051-1E/2E, antenna gain = 2.48dBi 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 0.996 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)] ·[√f(GHz)] f(GHz) is the RF channel transmit frequency in GHz Distance=5mm
