Diagnostics/Troubleshooting
For reducing EMC noise consider following options
•
use WLAN instead of LAN-cable
•
use wireless video transmitter instead of VGA-cable, DVI-cable, S-Video-cable, ...
If EMC noise does not depend on whether the ultrasound probe is contacted
When the EMC noise does not depend on whether the ultrasound probe is contacted (hold in hand/apply to
body), then do the following:
1. Hold the ultrasound probe only at the cable and change the orientation of the ultrasound probe.
2. If the EMC noise changes by changing the orientation of the ultrasound probe then the EMC noise is
caused by a magnetic field in the room/building.
In such situations the Power Filter (H48701EL) cannot reduce the EMC noise.
