The lower limit shall apply at the transition frequencies. 10.3.Test Procedure (1) The EUT was placed on a non-metallic table, 80cm above the ground plane. (2) Setup the EUT and simulator as shown in 10.1 (3) The EUT Power connected to the power mains through a power adapter and a line impedance stabilization network (L.I.S.N1). The other peripheral devices power cord connected to the power mains through a line impedance stabilization network (L.I.S.N2), this provided a 50-ohm coupling impedance for the EUT (Please refer to the block diagram of the test setup and photographs). Both sides of power line were checked for maximum conducted interference. In order to find the maximum emission, the relative positions of equipments and all of the interface cables were changed according to ANSI C63.10 :2013on conducted Emission test. (4) The bandwidth of test receiver is set at 10KHz. (5) The frequency range from 150 KHz to 30MHz is checked. 10.4.Test Result PASS.

Antenna Requirements 11.1.Limit For intentional device, according to FCC 47 CFR Section 15.203, an intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. And according to FCC 47 CFR Section 15.247 (b), if transmitting antennas of directional gain greater than 6dBi are used, the power shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6dBi. 11.2.Result The EUT antenna is Internal antenna. It complies with the standard requirement. Page 53 of 69 Report No.: A2103194-C01-R01 12.
