Same reason your computer needs an FCC ID - high frequency electrical circuits cause RF radiation in frequency bands regulated by the FCC.
Taken from Don's post:
I have searched the FCC database and found no results when seeking to find a Grantee Code assigned to Nanotech. Neither has a filing been made for a Produce Code for the missing NP-1. Those two codes combine to form the FCC mark of the device. The following explains why this is significant for those attempting to sell Class B electronic devices in the US.
Quote:All electronics products sold in the United States are required by the Federal Communications Commission (FCC) to obtain an FCC mark showing that the product complies with the following standards:
- Emissions (the effect on other electronic devices of energy radiated from the product)
- Immunity (the product's response to other electronic devices)
There are two categories that your product can fall into: Class A or Class B. A Class A device is a product marketed for commercial or industrial use and is not intended to to be used in a home. A Class B device is a product marketed for residential or home use. Class B requirements tend to be stricter than Class A requirements.
"The FCC Rules and Regulations, Title 47, Part 15, Subpart B regulates "unintentional radio-frequency devices". Products regulated include any unintentional radiator (device or system) that generates and uses timing pulses at a rate in excess of 9000 pulses (cycles) per second and uses digital techniques. This includes almost every product that employs a microprocessor including workstations, personal computers, point-of-sale terminals, printers, modems, and many electronic games. It is illegal to sell or advertise for sale any products regulated under Part 15, Subpart B until their radiated and conducted emissions have been measured and found to be in compliance.
