[RFI] Trying to locate the Part 15 compliance note...

Hello Dave E,
Many thanks for that link, that was statement I was looking for:
"This device complies with part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) This device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation."
Part (2) is exactly what I was talking about... I think because stoves
have been exempted from Part 15, the Part 15 notice is not there. Maybe
Ed can expand on this a bit more, as he is far more knowledgeable than I
in this sort of thing.
My hope is that somewhere the FCC has stated the part about accepting
interference for even non part 15 devices, I just can't locate it!
If I can locate that statement, then I just hand that off to the vendor,
and ask them to help the customer they sold the range to in front of the
customer.
73s and thanks,
Dave (NK7Z)
