The EUT and load, which are placed on a table that is 0.8 meter above ground, are placed with 
one coincident with the calibration plane such that the distance from antenna to the EUT was 3 
meters. 
Both horizontal and vertical polarization of the antenna and four sides of the EUT are set on 
measurement. 
In order to judge the EUT performance, a CCD camera is used to monitor EUT screen, and a 
plastic tube to monitor the sound output. 

All the scanning conditions are as follows:

The measurement of the radiated susceptibility was investigated and test result was shown in 
section 12. The acceptance criterion was met and the EUT passed the test.
