Product Wireless Charger, PPXWT-200WU, has been the units used for conducting FCC compliance testing, and it meets KDB 680106 Clause 5(2) all 6 conditions as stated below hence PBA is not required. 1 Power transfer frequency is less that 1 MHz The power transfer frequency is set from 110kHz to 205kHz. Therefore the frequency specification is satisfied with the device. 2 Output power from each primary coil is less than 5 watts The maximum output power of each coil is 5 watts. 3 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 The DUT(Device Under Test) includes only one coil in transmitter. A secondary coil is detected and coupled by transmitter. 4 Client device is inserted in or placed directly in contact with the transmitter When the client device is placed directly in contact with transmitter, then charging is able to start. 5 The maximum coupling surface area of the transmit (charging) device is between 60 cm2 and 400 cm2. The maximum coupling surface area of the transmitter is 87.52Cm2. Maximum coupling surface area(6.37 Cm X 13.74 Cm) 6 Aggregate leakage fields at 10 cm surrounding the device from all simultaneous transmitting coils are demonstrated to be less than 30% of the MPE limit. The highest leakage filed is less than 30 % of the MPE(Maximum Permissible Exposure) limit. If you have any question or concerns, pls. contact us. Sincerely, Client’s signature Name: Dong-Hyuk Hwang Address: 60, Jugyangdaero 1763Beon-gil, Wonsam-myeon, Cheoin-gu, Yong-in-si, Gyeonggi- do, Korea

Information about test items 2.1 Test Configuration and Mode ▪Test configuration The field strength of both E-field and H-field were measured at 10 cm using RF exposure survey meter with E-field and H- field probes for determining compliance with the MPE requirements of FCC Part 1.1310 During measurements, the wireless charging pad (EUT) was wirelessly charging a battery housed inside a portable handset and was loaded with the client device using the resistor as described below summary table for test modes and conditions. The RF power density was measured with the battery at 2 different charge conditions: battery at almost 0 % and 50 % status, 3 resistive load conditions: 300 mA, 600 mA, 1000 mA (Max. charging current with 5 Ω resister). These testing were performed at test configuration as test setup diagram on clause 3 of this test report. EUT was placed on a non-conductive turntable, and the portable handset with charging cover for charging a battery or client device with resistive load for drawing various load current. This device uses a wireless charging circuit for power transfer operating at the frequency of 110 KHz ~ 205 KHz. Thus, the 300 KHz RF exposure limits were used as below table. ▪Test mode This device has been tested with the below test modes and charging current conditions: Charging Current Support Equipment 300mA Wireless Charging Cover 600mA 1000mA(Max) ▪ Limit Frequency E-Field limit H-Field limit FCC Part 1.1310 300 kHz ~ 3 MHz 614 V/m 1.63 A/m 2.2 Tested environment Temperature : 23 ~ 25 o C Relative humidity content : 35 ~ 45 % R.H.

Pages: 6 / 7 3. E and H field strength For RF exposure purposes, the E and H field strengths are measured separately with E and H probes and meters at different locations surrounding the test setup. ▪ Test setup diagram ▪ Measurement procedure These testing were performed at test configuration as above diagram. EUT was placed on a turntable, and the measurement distance of 10 Cm from the center of the probe to the edge of the device. And test was performed all sides of the EUT(except bottom side). ▪Test equipment list Type Manufacturer Model Cal.Date (yy/mm/dd) Next.

Spectrum analyzers with pre-selectors and peak, quasi-peak detectors are used to perform radiated measurements. Conducted emissions are measured with Line Impedance Stabilization Networks and EMI Test Receivers. Calibrated wideband preamplifiers, coaxial cables, and coaxial attenuators are also used for making measurements. All receiving equipment conforms to CISPR Publication 16-1, “Radio Interference Measuring Apparatus and Measurement Methods.” FCC ID: PPXWT-200WU Report No.: DRTFCC1509-0203 TRF-RF-204(03)150922 Prohibits the copying and re-issue of this report without DT&C approval.
