No. Item Uncertainly 1 H-filed ±0.93dB 2 E-filed ±0.51dB 2 Requirements 2.1 According to the item 5.2 of KDB 680106 D01v04: Inductive wireless power transfer applications that meet all of the following requirements are excluded from submitting an RF exposure evaluation. a) The power transfer frequency is below 1 MHz. Yes.The device operates in the frequency from 115kHz to 205kHz. b) 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 15watts. c) 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. Client device is placed directly in contact with the transmitter. d) Only § 2.1091-Mobile exposure conditions apply (i.e., this provision does not cover § 2.1093-Portable exposure conditions). NO. The EUT is a portable wireless charger. e) 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. These measurements shall be taken along the principal axes of the device, with one axis oriented along the direction of the estimated maximum field strength, and for three points per axis or until a 1/d (inverse distance from the emitter structure) field strength decay is observed. Symmetry considerations may be used for test reduction purposes. The device shall be operated in documented worst-case compliance scenarios (i.e., the ones that lead to the maximum field components), and while all the radiating structures Yes. The EUT coil is evaluated at maximum output power and the test results are less than 50% of the limit. f) 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 power at the same time, as per design conditions. If the design allows one or more radiating structures to be powered at a higher level while other radiating structures are not powered, then those cases must be tested as well. NO, The EUT has one coil. 4 3 Method Of Measurement 3.1 Applicable Standard According to S1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission's guidelines.
