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: KDB 680106 D01 Wireless Power Transfer v04. 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.

Equipment Approval Considerations: The EUT does comply with item 5(b) of KDB 680106 V04 1) The power transfer frequency is below 1 MHz. Yes, the device operate in the frequency range from 110KHz to 205KHz 2) The output power from each transmitting element (e.g., coil) is less than or equal to 15 watts. Yes, the maximum output power of the primary coil is 3000mW. 3) A client device providing the maximum permitted load is placed in physical contact with the transmitter (i.e., the surfaces of the transmitter and client device enclosures need to be in physical contact). Yes, the surfaces of the transmitter and client device enclosures are in physical contact 4) Only § 2.1091-Mobile exposure conditions apply (i.e., this provision does not cover § 2.1093-Portable exposure conditions).. Yes, the EUT is a Mobile Wireless Charger 5) The E-field and H-field strengths, at and beyond 20 cm surrounding the device surface, are demonstrated to be less than 50% of the applicable MPE limit, per KDB 447498, Table 1. Yes, the EUT field strength levels are less 50% x MPE limit. 6) For systems with more than one radiating structure, the conditions specified in (5) must be met when the system is fully loaded (i.e., clients absorbing maximum power available), and with all the radiating structures operating at maximum power at the same time, as per design conditions. Yes, the EUT has only one coil，all test modes met the conditions specified in (5). 4.3. E and H field Strength Shenzhen CTB Testing Technology Co., Ltd. Report No.: CTB231011005RFX EMF Report Tel…
