All, I concur with Rich Nute. The LED light bulb in the bathroom shower interferes with the FM radio used in the adjoining bedroom.

Agreed, but the real issue is the ambiguity of 'may not'. It can be interpreted as anything from 'shall not' or 'must not' to 'might not (but might)'. It really should be clarified.

Re: [PSES] FCC regulatory statements
Hi John, The radio listening law was around many decades ago. Usually we just had a #47 pilot lamp on a radio instead of the speaker to know when the station went off the air. At that point, one was to listen on 640 or 1240 kHz. Only required of ham radio operators. That went away decades ago. I like that for most equipment there are no immunity requirements in the US. The market is a very strong force and will eliminate companies whose equipment does not work in its environment. The standards should be there but not required. I buy stuff from overseas that I know is not likely to pass all the immunity tests, but I do not care. I ascertain if it will work for what I want. I would rather not pay for testing I do not need.

Re: [PSES] FCC regulatory statements
Apologize if someone else has already answered Rich Nute’s question. Part (2) interpretation is incorrect. It means that if your Part 15 widget is susceptible to rf from some licensed transmitter, that’s tough. You don’t get to complain about it. It doesn’t mean you are prohibited from using the widget.

Re: [PSES] FCC regulatory statements
Well, technically the label for FM and Land mobile receivers is different, per 15.19 (a) (1) from all other devices and does not contain the two parts. This device complies with part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference.

Re: [PSES] [EXTERNAL] Re: [PSES] FCC regulatory statements
I would read the FCC two-part statement a little differently. Let's start with the second statement. It indicates that equipment must accept interference. It uses "must", so this is a requirement. This just indicates that the product falls under a category where there are no immunity requirements mandated by the FCC. It's a warning to the user. If they find that their device is misbehaving due to interference from other devices, the user is being told that it isn't the fault of the FCC. The first statement is harder to figure out. I can start with the signal words. "Must" means a requirement, "should" indicates a recommendation, and "may" indicates an option. What does "may not" mean? A prohibition should be "must not" or "shall not". A recommendation against would be "should not". However, as written it could be interpreted to mean that the equipment might not cause harmful interference. I don't know if that is what is intended, but that is how it could be interpreted if read literally. The way I look at it, these statements are to make it clear to the user that the FCC is absolving itself of any fault for accepting the certification of the device. First, if your equipment causes interference with other devices, blame the manufacturer and not the FCC. Second, if your equipment is susceptible from interference from other devices, blame the manufacturer and not the FCC.
