I agree with John (as I usually do). We purchased an electronic device a few years ago in the US and it came is a bag of snap-on ferrite beads and instructions to what cables they had to be put on; even though not all the cables were provided. For instance, if I used a USB printer then one of the beads where to go on the USB cable.
I have seen instructions for electronic devices that require the customer to purchase shielded I/O cables. I've even seen where shielded Ethernet cables are required (usually short jumper cables between server and switch). I used to work for a PC company and the rule was No Ferrite Beads on I/O cables because Marketing says it gives the appearance of a low quality product, but today is not unusual to see two or three cables on your PC with molded ferrite beads. What more can be expected from any company than to provide the means and instructions to their customer on how to setup and use the product so it is compliant to the FCC regulations?

That may be OK for a power cable, as they are usually fairly short and provided with the product anyway. But surely it's impracticable for a LAN cable, that could be 500 m long! -- OOO - Own Opinions Only. With best wishes.
