4.4.2        Test Procedures

E and H-field measurements should be made with the center of the probe at a distance of 15 cm
surrounding the device and 20 cm above the top surface of the primary/client pair.

These measurements should be repeated for three different client battery levels, 1%, 50%, and 99%.

Record the test results.

KDB 680106 D01 RF Exposure Wireless Charging App v03:

(1) Power transfer frequency is less than 1MHz.

(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.

Note: The device is in compliance with KDB 680106 D01 RF Exposure Wireless Charging App v03 6
conditions.
