Product Description The EUT is Wireless Handheld Microphone Operation Frequency: 204-215MHz Modulation Type: GFSK Antenna gain: 2.5dBi Antenna Designation: PCB Antenna Rating Two AA batteries(DC 3V from battery) Hardware Version BY-WHM12 V1.1 Software Version V1.3 1.2 TEST FACTORY SHENZHEN STS TEST SERVICES CO., LTD Add. : A 1/F, Building B, Zhuoke Science Park, No.190 Chongqing Road, HepingShequ, Fuyong Sub-District, Bao’an District, Shenzhen, Guang Dong, China FCC test Firm Registration Number: 625569 IC test Firm Registration Number: 12108A A2LA Certificate No.: 4338.01 Page 6 of 8 Report No.: STS2105122H02 2. FCC 47CFR §2.1093 REQUIREMENT 2.1 TEST STANDARDS The limit for Maximum Permissible Exposure (MPE) specified in KDB 447498 D01 General RF Exposure Guidance v06 is followed. The gain of the antennas used in the product is extracted from the Antenna data sheets provided and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis Transmission formula is far field assumption, the calculated result of that is an over-prediction for near field power density. It is taken as worst case to specify the safety range. 2.2 LIMIT Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. Page 7 of 8 Report No.: STS2105122H02 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 f(GHz) is the RF channel transmit frequency in GHz. Power and distance are rounded to the nearest mW and mm before calculation The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. Page 8 of 8 Report No.: STS2105122H02 2.3 TEST RESULT Maximum measured transmitter power. The Worst Case Mode frequency Maximum Output Power Tune up tolerance Max Tune up MHz dBm dBm dBm GFSK 210 7.27 7±1 8 Remark: The worst case gain of the antenna is 2.5dBi. 2.5dBi logarithmic terms convert to numeric result is nearly 1.78. Maximum Tune up Power (210) = 6.31mw [(power of channel, including tune-up tolerance, mW)/(min. test separation distance,mm)] · [√f(GHz)]= 6.31/5*√0.210=0.578≤3.0 Threshold at which no SAR required is 0.578≤ 3.0 for 1-g SAR, Separation distance ≤ 5mm. ※※※※※END OF THE REPORT※※※※※
