1 CONCLUSION The equipment under test (EUT) meets the essential requirements of the EMC Directive 2004/108/EC. This report is base on report G080144A.900. In this update, the applied standards were upgraded. After reviewing, the radiated emission test was selected to repeat on models KLP350, KLP350x3 and KLP700 and the radiated magnetic emission test was selected to repeat on model KLP350x3 which with maximum power for verification. The test results in this report belong to models KLP350, KLP350x3 and KLP700. The conclusion and results stated in this test report are based on a non-recurrent examination of sample(s) provided by the applicant.

PST ≤ 1

PLT ≤ 0,65

dt > 3,3% ≤ 500 ms
