The other emission levels were very low against the limit. 4. Margin value = Emission Level – Limit value Page 22 of 33

Report No.: SET2019-16118 2.7. Conducted Emission 2.7.1. Limit of Conducted Emission For equipment that is designed to be connected to the public utility (AC) power line, the radiofrequency voltage that is conducted back onto the AC power line on any frequency or frequencieswithin the band 150 kHz to 30 MHz shall not exceed the limits in the following table. Conducted Limit (dBµV) Frequency range (MHz) Quai-peak Average 0.15 - 0.50 66 to 56 56 to 46 0.50 - 5 56 46 5 - 30 60 50 2.7.2. Measuring Instruments The measuring equipment is listed in the section 3 of this test report. 2.7.3. Test Setup Page 23 of 33

Report No.: SET2019-16118 2.7.4. Test Procedures 1. The EUT was placed 0.4 meter from the conducting wall of the shielding room was kept at least80 centimeters from any other grounded conducting surface. 2. Connect EUT to the power mains through a line impedance stabilization network (LISN). 3. All the support units are connecting to the other LISN. 4. The LISN provides 50 ohm coupling impedance for the measuring instrument. 5. The FCC states that a 50 ohm, 50 microhenry LISN should be used. 6. Both sides of AC line were checked for maximum conducted interference. 7. The frequency range from 150 kHz to 30 MHz was searched. 8. Set the test-receiver system to Peak Detect Function and specified bandwidth (IF Bandwidth = 9kHz) with Maximum Hold Mode. Then measurement is also conducted by Average Detector and Quasi-Peak Detector Function respectively. 2.7.5. Test Result The EUT configuration of the emission tests is Bluetooth Link + USB Cable (Charging from Adapter) Page 24 of 33
