Equipment Approval Considerations: The EUT does comply with item 5(b) of KDB 680106 V03R01 1) Power transfer frequency is less than 1MHz Yes, the device operate in the frequency range from 300kHz-350kHz 2) Output power from each primary coil is less than or equal to 15 watts. Yes, the maximum output power of the primary coil is 15000mW. 3) The transfer system includes only single primary and secondary coils. This includes charging systems that may have multiple primary coils and clients that able to detect and allow coupling onlybetween individual pair of coils. Yes, the transfer system includes only single primary and secondary coils. 4) Client device is inserted in or placed directly in contact with the transmitter. Yes, client device is placed directly in contact with the transmitter. 5) Mobile exposure conditions only (portable exposure conditions are not covered by this exclusion). No, submit a KDB inquiry to get test guideline and fully follow the KDB inquiry guideline. 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. Yes, the EUT field strength…
