| TM1 | Wireless charging | Transmit | DC 5V (with a adapter input AC 120V/60Hz) |
Measurement Distance: 15 cm
2.3 Test Procedure
Test Setup Description: The measurement probe was placed at test distances of 15 cm for points A, B, C, D, F, and 20 cm for point E, which is between the edge of the charger and the geometric center of the probe. The highest emission level was recorded at these measurement points (A, B, C, D, E, F). The EUT was measured according to the distance requirements of KDB 680106 D01 V03.
2.4 Test Result
The EUT complies with item 5.2 of KDB 680106 D01V03.
