FCC ID: 2AQUQGL52275 Test date:2018-12-31 RF Exposure Considerations 1. Measuring Standard KDB 680106 D01 RF Exposure Wireless Charging Apps v02 2. TEST MODE Test Mode Description Remark TM1 5W OUTPUT With mobile phone 3. 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. a) Power transfer frequency is less than 1 MHz. b) Output power from each primary coil is less than or equal to 15 watts. c) 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 d) Client device is placed directly in contact with the transmitter. e) Mobile exposure conditions only (portable exposure conditions are not covered by this exclusion). f) 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. 4.

FCC ID: 2AQUQGL52275 Test date:2018-12-31 5. Test Setup Note: Measurements should be made from all sides and the top of the primary/client pair, with the 10cm measured from the center of the probe(s) to the edge of the device. 6. Test Procedure 1) The RF exposure test was performed in anechoic chamber. 2) The measurement probe was placed at test distance (15cm) which is between the edge of the charger and the geometric center of probe. 3) The highest emission level was recorded and compared with limit as soon as measurement of each points (A, B, C, D, E, F) were completed. 4) The EUT was measured according to the dictates of KDB 680106 D01 v02. Remark: The EUT’s test position A, B, C, D, E and F is valid for the E and H field measurements 7.
