Been reading the gobs of FCC part 15 docs this past weekend and will summarize eventually after I've read all the relevant parts. However, I can add a few clues. Experts feel free to chime in and correct me if necessary. If your device does not purposely generate RF signals, it is classified as an unintentional radiator. There are standards to be met, but there are exemptions available for various devices. (Exempt from having the device tested/certified -- this does not mean that you are exempt from creating emissions beyond a certain level). There are exemptions for battery operated devices not consuming more than some ridiculously low level of power (IIRC 6nW), and digital devices operating below 1.705MHz. There is also an exemption for devices in a transportation vehicle (car or airplane), but I'm not sure if an RC airplane classifies as true transportation. Unless you promise to deliver something everytime you fly it :-) There is also special situations for items sold as kits -- so perhaps that might meet your requirements. Labelling pretty much needs to say that it meets FCC part 15 standards. Also, the rules are written as if they're nice about it -- if it's found that your device emits more than the limit of emissions, then you get a slap on the wrist, and meet the compliance requirements. Obviously lots of paraphrasing here, so these are really just clues. I recommend you read part 15 for yourself.

I'm about to start on producing my first commercial product (100% developed and produced by me, that is), which is intended for the model airplane (hobby) industry. I hope to produce at least a few hundred per year. Basically it's an in-flight monitor (no RF or telemetry) that stores measured values of altitude, etc. The unit operates at 4 MHz and borrows power from the flight battery pack of the radio control. (I don't know if any of this matters, but I'm including it for information.) Do I have to be concerned about FCC compliance for this application? That is, do I have to have this formally certified in order to sell it commercially? Does it need some sort of markings on the package that indicate compliance? Or can I just "let the buyer beware" so to speak? I feel that this is a relatively innocuous application, and this isn't going to cause problems with the radio controls (they typically operate in the 72 KHz range), as I've tested it on a number of airplanes using various radios. --Andrew _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
