For devices designed for typical desktop applications, such a wireless charging pads, RF exposure evaluation should be conducted assuming a user separation distance of 15 cm. E and H field strength measurements or numerical modeling may be used to demonstrate compliance. Measurements should be made from all sides and the top of the primary/client pair, with the 15 cm measured from the center of the probe(s) to the edge of the device. Emissions between 100 kHz to 300 kHz should be assessed versus the limits at 300 kHz in Table 1 of Section 1.1310: 614 V/m and 1.63 A/m. A KDB inquiry is required to determine the applicable exposure limits below 100 kHz. FCC ID: 2ARDY-T580-F EST Technology Co., Ltd Report No. ESTE-R2010150 Page 6 of 15 2.2. Test Setup 2.3. Test Procedure a. The test was performed on turn table in anechoic chamber with a dummy load. b. The dummy load must be placed horizontal of the EUT at the top (Parallel to the coil). c. The probe was placed at 15 cm surrounding the device and 20 cm above the top of the charger and the geometric centre of the probe. d. The highest emission level was recorded and compared with limit as soon as measurement of each point; A, B, C, D, E were completed. FCC ID: 2ARDY-T580-F EST Technology Co., Ltd Report No. ESTE-R2010150 Page 7 of 15 2.4. Equipment Approval Considerations Inductive wireless power transfer applications with supporting field strength results and meeting all of the following requirements are not required to submit a KDB inquiry for devices approved using SDoC or a PAG for equipment approved using certification to address RF exposure compliance. 1. Power transfer frequency is less that 1 MHz YES; the device operated in the frequency range from 110.5-168KHz. 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 15W. 3. The transfer system…
