Measurements in both horizontal and vertical polarities were performed. During the test, each emission was maximized by: having the EUT continuously working, investigated all operating modes, rotated about all 3 axis (X, Y & Z) and considered typical configuration to obtain worst position, manipulating interconnecting cables, rotating the turntable, varying antenna height from 1m to 4m in both horizontal and vertical polarizations. The emissions worst-case are shown in Test Results of the following pages. The worst case is X position EUT Page 8 of 22 Report No.: HK2104161155-E 2.5 MEASUREMENT INSTRUMENTS LIST Item Equipment Manufacturer Model No. Serial No. Last Cal. Cal. Interval 1. L.I.S.N.
