Hello Everyone,
A lot of "budding midnight designers" ask these questions on the
microcontroller newsgroups so I thought I'd ask them here - and learn
something :)
(If I've missed some FAQ that covers this please let me know.)
1) Say I'm building some microcontroller based widget in my home
business that runs model trains (or whatever). It's not an intential
transmitter, its typically used in the home. And I want to sell them.
Do I need some FCC approval.
Specifically do I need to:
1.a) Spend money having someone test emissions.
1.b) File some paperwork with the FCC.
2) If I don't have the money for testing - but I really do know how
to keep my microcontroller quiet (i.e I know loop area, di/dt, and
maybe even have done lots of other 'approved' products) - and a
little in-home testing shows it doesn't bother the rabbit ears or
show-up on the AM or FM radio. Would I be in violation of some law if
I just sold the darn thing.
2.a) Would I be in violation if it really was quiet to CISPR (i.e.
would have passed). (i.e. is there now a CE mark like compliance that
lets me self declare and assert who's responsible).
3) How does the FCC verify that I don't pollute the EM band - do they
random sample train widgets or wait for someone to complain.
Thanks,
Jon Bertrand
