FCC Rule: 15.109(a) ICES-003: 3.2.2

Test plan
The radiated emission measurements were done within a semi anechoic screened chamber. Additional floor absorbers were used on the floor between the EUT and receiving antenna in radiated emission test above 1 GHz. The EUT was placed on a table 0.8 m above the reflecting ground plane.The measurement distance was 3 meters. The worst interferences were determined during measurements by rotating the turntable and adjusting the antenna height. The measurements were done in horizontal and vertical antenna polarizations. The supply voltage to the turntable was fed through the filter.
The EUT was working as described in the section "EUT Test Conditions" using Operation modes 1 and 2. Above 1 GHz only the results with Operation mode 1 are presented.
