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 system may consist of more than one source primary coils, charging one or more clients. If more than one primary coil is present, the coil pairs may be powered on at the same time. (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 anywhere at or beyond 15 cm surrounding the device, and 20 cm away from the surface from all coils that by design can simultaneously transmit, and while those coils are simultaneously energized, are demonstrated to be less than 50% of the applicable MPE limit. Limits For Maximum Permissible Exposure (MPE) Report No.: TBR-C-202212-0096-1 Page: 3 of 11 TB-RF-074-1.0 3. Test Setup 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. 15cm Report No.: TBR-C-202212-0096-1 Page: 4 of 11 TB-RF-074-1.0 5.

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. Yes The transfer system includes only single primary and secondary coils. Charging systems have two primary coils and clients that are able to detect and allow coupling only between individual pairs of coilsand the coil pairs powered on at the same time. Client device is placed directly in contact with the transmitter. Yes Client device is placed directly in contact with the transmitter. Mobile exposure conditions only (portable exposure conditions are not covered by this exclusion). Yes Mobile exposure conditions and mobile exposure conditions 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. Yes The EUT 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. In all other cases, unless excluded above, an RF exposure evaluation report must be reviewed and accepted through a KDB or PBA inquiry to enable authorization of the equipment. When evaluation is required to show compliance; for example, using field strength, power density, SAR measurements or computational modeling etc., the specific authorization requirements will be determined based on the results of the RF exposure evaluation 6.
