Here is some interesting info on FCC part 15

http://www.arrl.org/tis/info/part15.html#Myths

Interesting. Part 15 sticker may not necessarily mean it meets it.
(Read article above, honor system)

However, Part 15 does address a very small amount of *harmful interference*
but not necessarily none. It also describes classes and other good info.

Read link above, it is written in easy to understand English and I found it
very interesting.
