The latest thread regarding FCC compliance got me thinking. 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.
