>From your research, would you conclude that the machine did not comply  with 
emc regulations?

This sort of problem is, as we all know, common with many imported 
computers, shipped with filters designed in but obviously missing.

Is this a sign that industry in general is prepared to save a few $ per 
machine and have very few complaints from their customers?  After all, as a 
proportion of the population, how many would notice?
