FCC RF Exposure EUT Description: Wireless Dual-band USB Adapter Model No.: NCU‐L1300 FCC ID : X4YLNX13AC 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 Output power （dBm） Tune Up Power （dBm） Max Tune Up power dBm/mW Min test separatio n distance mm Result Limit SAR Test Exclusion 2.4GWIFI 7.32 7±1 8/ 6.31 5 1.96 3.0 Pass 5.2GWIFI 6.76 6±1 7/ 5.01 5 2.28 3.0 Pass 5.8GWIFI 7.26 6.5±1 7.5/5.62 5 2.69 3.0 Pass Note: PK Output power= conducted power.

The test exclusion threshold is 2.69 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 Note: the device could not transmit simultaneously in 2.4G and 5G.
