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 §2.1093 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 20 cm-0cm measured from the center of the top, and 15cm-0cm measured from the center of the rest Test Procedure: a) The RF exposure test was performed on 360 degree turn table in anechoic chamber. b) 20 cm-0cm measured from the center of the top, and 15cm-0cm measured from the center of the rest sides.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 680106 D01 RF Exposure Wireless Charging App v03r01. 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 D01 RF Exposure Wireless Charging App 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 1000mW. 3) The system may consist of more than one source primany coils, charging one or more chients, if more than one primary coils is present, the coil pairs may be powered on at the same time. Ye s , the transfer system includes only single primary 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). No, submit a KDB inquiry to get test guideline and fully follow the KDB inquiry guideline. 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.
