For devices designed for typical desktop applications, such a wireless charging pads, RF exposure evaluation should be conducted assuming a user separation distance of (AC Mode: H-field & E- field strengths for all sides is 15cm, H-field strengths of top side is 20cm) and (DC Mode: H-field & E- field strengths for all sides is 0cm, H-field strengths of top side is 0cm) E and H field strength measurements or numerical modeling may be used to demonstrate compliance. 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. 4.1 Test Setup AC Mode: DC Mode: Page 7 of 16 Report No.: HK2312206220-2E 4.2 Result of Maximum Permissible Exposure AC Mode: For Full load: H-Field Strength at 15 cm (E top side: 20cm) from the edges surrounding the EUT (A/m) Field strength Test Position A Test Position B Test Position C Test Position D Test Position E Limits (A/m) A/m 0.2101 0.2330 0.2251 0. 2164 0.2083 1.63 For Half Load mode: H-Field Strength at 15 cm (E top side: 20cm) from the edges surrounding the EUT (A/m) Field strength Test Position A Test Position B Test Position C Te…
