RF Exposure Evaluation Test report On Behalf of VTIN TECHNOLOGY Co.,Limited For wireless mouse Model No.: PC299A FCC ID: 2AIL4-PC299A Prepared for : VTIN TECHNOLOGY Co.,Limited UNIT D 16/F ONE CAPITAL PLACE 21 LUARD ROAD WAN CHAI, Hong Kong, China Prepared By : Shenzhen HUAK Testing Technology Co., Ltd. 1F, B2 Building, JunfengZhongchengZhizao Innovation Park, Fuhai Street, Bao'an District, Shenzhen City, China Date of Te st: Jun. 15, 2020 ~ Jun. 29, 2020 Date of Re port: Jun. 29, 2020 1 General Description of EUT Product Name wireless mouse Model/Type reference PC299A Trade Mark VICTSING FCC ID 2AIL4-PC299A Hardware Version ZM2.1 Software Version VER4.0 Operation frequency 2402.4MHz--2480.4MHz Channel number 16 Modulation Technology GFSK Antenna Type PCB Antenna Antenna Gain 0dBi Power Supply DC 1.5V from Dry cell 2 RF Exposure ComplianceRequirement 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, Wheref(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearsetmW and mm before calcution The results is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mmand for transmission frequencies between 100 MHz and 6 GHz. When the minimum testseparationdistance is < 5 mm, a distance of 5 mm is applied to determine SAR testexclusion 3 EUT RFExposure Antenna Gain: 0dBi Define the minimum distance: 5mm GFSK Channel Maximum Peak Conducted Output Power (dBm) Tune up tolerance (dBm) Maximum tune-up Power Calculated value Exclusion threshold (dBm) (mW) Lowest (2402.4MHz) -9.160 -9±1 -8 0.158 0.049 3.0 Middle (2441.4MHz) -8.187 -9±1 -8 0.158 0.050 Highest (2480.4MHz) -9.082 -9±1 -8 0.158 0.050 Conclusion: the calculated value ≤3.0, SAR is exempted. Note: For maximum peak conducted output power, please refer to Test report HK2006181455-E
