For devices designed for typical desktop applications, such a wireless charging pads, RF exposure evaluation should be conducted assuming a user separation distance of (H-field & E- field strengths for all sides is 15cm, H-field strengths of top side is 20cm). 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 4.2 RESULT OF MAXIMUM PERMISSIBLE EXPOSURE Page 6 of 8 Report No.: HK1912063127-02E For Full load mode: E-Field Stre ngth at 15 cm fro m the edges surrounding the EUT (V/m) Frequency Range (MHz) Test Position A Test Position B Test Position C Test Position D Test Position E Limits Test (V/m) 0.125 2.05 1.59 1.25 2.08 1.62 614 H-Field Strength at 15 cm fro m the edges surrounding the EUT (A/m) Frequency Range (MHz) Test Position A Test Position B Test Position C Test Position D Test Position E Limits Test (A/m) 0.125 0.180.210.140.210.04 0.815 For Half Load mode: E- Field Strength at 15 cm from the edges surrounding the EUT (V/m) Frequency Range (MHz) Test Position A Test Position B Test Position C Test Position D Test Position E Limits Test (V/m) 0.125 1.33 1.83 0.64 1.53 1.80 614 H-Field Strength at 15 cm from the edges surrounding the EUT (A/m) Frequency Range (MHz) Test Position A Test Position B Test Position C Test Position D Test Position E Limits Test (A/m) 0.125 0.11 0.270.25 0.190.14 0.815 Page 7 of 8 Report No.: HK1912063127-02E For No load mode: E-Field Strength at 15 cm from the edges surrounding the EUT (V/m) Frequency Range (MHz) Test Position A Test Position B Test Position C Test Position D Test Position E Limits Test (V/m) 0.125 2.18 1.25 1.26 1.52 1.86 614 H-Field Strength at 15 cm from the edges surrounding the EUT (A/m) Frequency Range (MHz) Test Position A Test Position B Test Position C Test Position D Test Position E Limits Test (A/m) 0.125 0.25 0.10 0.14 0.260.31 0.815 Remark: According KDB 680106 D01 RF Exposure Wireless Charging App v03, section 5, b).
