  It is well known to us who work in this field that the FCC
  noise limits for computing equipment are so loose that even if
  the equipment - with or without the wiring - meets the specs,
  there is still sufficient signal radiated to cause harmful
  interference.

  The law does require that the operator of the offending
  equipment cease operation if harmful interference is being
  caused, but this is a very delicate situation because in
  general the operator of the equipment does not have the
  technical savvy to understand why and how interference is being
  caused.

  If not handled correctly, the problem then escalates from a
  technical problem to a legal confrontation, which is never
  pleasant.
