Equipment Approval Considerations: The EUT does comply with item 5(b) of KDB 680106 V04 1) Power transfer frequency is less than 1MHz Yes, the device operate in the frequency range from 110kHz to 205kHz 2) The output power from each transmitting element (e.g., coil) is less than or equal to 15 watts. Yes, the maximum output power of the primary coil is 15000mW. 3) A client device providing the maximum permitted load is placed in physical contact with the transmitter (i.e., the surfaces of the transmitter and client device enclosures need to be in physical contact). Yes, the surfaces of the transmitter and client device enclosures are in physical contact 4) Only § 2.1091-Mobile exposure conditions apply (i.e., this provision does not cover § 2.1093-Portable exposure conditions).. No, the EUT is portable condition assessment. 5) The E-field and H-field strengths, at and beyond 20 cm surrounding the device surface, are demonstrated to be less than 50% of the applicable MPE limit, per KDB 447498, Table 1. Yes, the EUT field strength levels are less 50% x MPE limit. 6) For systems with more than one radiating structure, the conditions specified in (5) must be met when the system is fully loaded (i.e., clients absorbing maximum power available), and with all the radiating structures operating at maximum powe…
