Submitted Documents: Circuit diagram, user's manual, and rating label.

Test Set-up and Operation Modes

Principle of Configuration Selection

For emission testing, the EUT was configured to measure its highest possible emission level. Test conditions were adapted according to the instructions for use. Conducted emission tests were performed on 2025-01-09, and radiated emission tests were performed on 2025-01-15.

Equipment and Cable Arrangement

The test setup involved the following components:

• Conducted Emission Setup: EUT, LISN (Line Impedance Stabilization Network), EMI receiver, Computer, Transformer, and Power Supply.
• Radiated Emission Setup: EUT, Antenna, EMI receiver, within a semi-anechoic chamber.

The EUT was placed on an 80 cm wooden support above the reference ground plane. The interconnecting cable was folded to a length between 0.3 m and 0.4 m.

Special Accessories and Auxiliary Equipment

During the EMI tests, a dimmer (model: ICDL-20NA-BI-2, brand: IKEA) was used.

Countermeasures to Achieve EMC Compliance

No special measures were employed to achieve EMC compliance beyond standard setup.

Conformity Decision Rule

For all EMI tests in this report, compliance with limits is determined by directly comparing measurement results with corresponding limits, as measurement uncertainties are less than the values specified in CISPR 16-4-2. This approach does not take measurement uncertainties into consideration.
