                              RF Exposure Considerations
1. Measuring Standard
   KDB 680106 D01 RF Exposure Wireless Charging App v03.
2. Requirements
   According to the item 5.2 of KDB 680106 D01v03:
   Inductive wireless power transfer applications that meet all of the following requirements
   are excluded from submitting an RF exposure evaluation:
   (1) Power transfer frequency is less than 1 MHz.
   (2) Output power from each primary coil is less than or equal to 15 watts.
   (3) The transfer system includes only single primary and secondary coils. This includes
   charging systems that may have multiple primary coils and clients that are able to detect
   and allow coupling only between individual pairs of coils.
   (4) Client device is placed directly in contact with the transmitter.
   (5) Mobile exposure conditions only (portable exposure conditions are not covered by this
   exclusion).
   (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.

3. Test Setup




                                                15cm




Note: The aggregate H-field strengths at 15 cm surrounding the device and 20 cm above the top
surface.

4.Test Procedure
     1) The RF exposure test was performed in anechoic chamber.
     2) The aggregate H-field strengths at 15 cm surrounding the device and 20 cm above the
     top surface.
     3) The highest emission level was recorded and compared with limit as soon as
     measurement of each points (A, B, C, D, E) were completed.
     4) The EUT was measured according to the dictates of KDB 680106 D01 v03.
     Remark:
     The EUT’s test position A, B, C, D and E is valid for the E and H field measurements.
