METHOD OF MEASUREMENT 3. 1.Applicable Standard According to §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to §1.1310 and §2.1091 RF exposure is calculated. According KDB680106 D01: RF Exposure Wireless Charging Apps v 03r01. 4. TEST RESULT 4.1. Conducted Emission at the Mains Terminals Test Note: Measurements should be made from all sides and the top of the primary/client pair, with the 15 cm measured from the center of the probe(s) to the edge of the device Test Procedure: a) The RF exposure test was performed on 360 degree turn table in anechoic chamber. b) The measurement probe was placed at test distance (15cm) which is between the edge of the charger and the geometric centre of probe. c) The turn table was rotated 360d degree to search of highest strength. d) The highest emission level was recorded and compared with limit as soon as measurement of each points were completed. e) The EUT were measured according to the dictates of KDB 680106v03r01. EMF Report Te l : 4008-707-283 Web: http://www.ctb-lab.net Page5 of 10 4.2. Equipment Approval Considerations: The EUT does comply with item 5(b) of KDB 680106 V03R01 1) Power transfer frequency is less than 1MHz Ye s , the device operate in the frequency range from 110KHz to 205KHz 2) Output power from each primary coil is less than or equal to 15 watts. Ye s , the maximum output power of the primary coil is 5000mW. 3) The transfer system includes only single primary and secondary coils. This includes charging systems that may have multiple primary coils and clients that able to detect and allow coupling onlybetween individual pair of coils. Ye s , the transfer system includes only single primary and secondary coils. 4) Client device is inserted in or placed directly in contact with the transmitter. Ye s , client device is placed directly in contact with the transmitter. 5) Mobile exposure conditions only (portable exposure conditions are not covered by this exclusion). Ye s , the EUT is a Mobile Wireless Charger 6) The aggregate H-field strengths at 15 cm surrounding the device and 20 cm above the top surface from all simultaneous transmitting coils are demonstrated to be less than 50% of the MPE limit. Ye s , the EUT field strength levels are less 50% x MPE limit. 4.3.
