Hello Gary, I know Panasonic supply clip-on ferrite cores with some of their TV's with the instruction to fit them to certain cables the end user plugs into the TV.
This would seem a sensible approach where the manufacturer doesn't supply all the cables that will be plugged into their product but where they know their product may conduct EMI from those ports. Your scenario seems like a perfect example of this. You wouldn't expect to receive LAN cables with a PC but if you know you emit from that port then you provide the user with the means to suppress those emissions. Just my thoughts...
