R-88 Attaching the Ferrite Core
You must attach the ferrite core before using the R-88.
If you use a commercially available USB cable to connect the R-88 to your computer, you must attach the included ferrite core.
This is for the purpose of preventing electromagnetic noise; do not remove it.
Ferrite Core
1. Open the ferrite core and position it over the cable.
* You must attach the ferrite core near the plug that is connected
to the R-88.
2. Wrap the cord around the ferrite core; one turn is enough.
3. Close it rmly; you should hear a distinct sound as it clicks
shut.
* Take care not to get your ngers pinched when attaching the
ferrite core.
* Make sure you don’t apply undue force and damage the cord
when clamping on the ferrite core.
Depending on the thickness of the USB cable, you might not
be able to close the ferrite core with the cable wrapped once
around it. Use a cable of a thickness that allows the ferrite core
to be attached with the cable wrapped once around it.
