Even after 30 years of playing with FCC-certified toys, I've 
never understood that wording.  Most computer equipment I've 
used has at least SOME shielding from outside RFI, which would 
seemingly violate the terms you're describing, which are from 
FCC Part 15.  I've heard people claim that it was just intended 
to provide a shield to the manufacturers against consumer 
complaints when RFI did impair their use of the product, but I 
would think they'd have made that a little less cryptic.

Has any audio or computer equipment manufacturer ever been fined 
by the FCC for NOT crashing when the neighbor turns on his 
blender (or when the guys in dark sunglasses sitting in the 
flower delivery truck in the parking lot turn on their 
computer-crashing ray gun?)  This seems like one of 
those "Straight Dope" kind of questions, but I can't find a 
definitive answer.
