Usually, when the product complies with certain Emissions/Immunity FCC regulations on interference with different devices it is getting an approval for a certain FCC Class. Majority of Electronics targeted at consumers bare FCC Class B certification meaning they will cause less interference while operating in residential installs, while Class A is really for the "industrial" type of the environment. I can get deep into detail but not sure if it will be interesting for forum members. I have a Plasma display which conforms to FCC Class A. If another TV is turned on in another bedroom I can see interference lines caused by the Plasma. If you can - try getting a device which bares FCC Class B approval.
