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.: HK2005081216-3E For Full load mode: E-Field Strength at 15 cm from the edges surrounding the EUT (V/m) Frequency Range (MHz) Te s t Position A Te s t Position B Te s t Position C Te s t Position D Te s t Position E Limits Te s t (V/m) 0.125 1.66 1.47 1.32 1.41 1.20 614 H-Field Strength at 15 cm from the edges surrounding the EUT (A/m) Frequency Range (MHz) Te s t Position A Te s t Position B Te s t Position C Te s t Position D Te s t Position E Limits Te s t (A/m) 0.125 0.69 0.70 0.25 0.11 0.45 1.63 For Half Load mode: E-Field Strength at 15 cm from the edges surrounding the EUT (V/m) Frequency Range (MHz) Te s t Position A Te s t Position B Te s t Position C Te s t Position D Te s t Position E Limits Te s t (V/m) 0.125 1.12 1.47 1.25 1.73 1.34 614 H-Field Strength at 15 cm fro m the edges surrounding the EUT (A /m) Frequency Range (MHz) Te s t Position A Te s t Position B Te s t Position C Te s t Position D Te s t Position E Limits Te s t (A/m) 0.125 0.31 0.45 0.22 0.17 0.57 1.63 Page 7 of 8 Report No.: HK2005081216-3E For No load mode: E-Field Stre ngth at 15 cm from the edges surrounding the EUT (V/m) Frequency Range (MHz) Te s t Position A Te s t Position B Te s t Position C Te s t Position D Te s t Position E Limits Te s t (V/m) 0.125 1.25 1.37 1.65 1.45 1.66 614 H-Field Strength at 15 cm from the edges surrounding the EUT (A/m) Frequency Range (MHz) Te s t Position A Te s t Position B Te s t Position C Te s t Position D Te s t Position E Limits Te s t (A /m) 0.125 0.57 0.68 0.44 0.49 0.60 1.63 Remark: According KDB 680106 D01 RF Exposure Wireless Charging App v03, section 5, b).
