Now, I had response from FCC OET. <QUOTE> Inquiry: These days, internal-combustion engine driven heavy machines such as cranes, excavators, etc. may have several microprocessors and other electronic circuits, and such machines may be used also in residential areas. Will such machines be covered by the FCC Rules, especially the Part 15? If such machines can be exempted, what is the rationale? I know of 47 CFR 15.103(a), but I think such movable machines may not transportation vehicle, and even if such machinery can be categorized as transportation vehicle, I think KDB 892282 suggests that such machines will not be exempted. And if engine driven machines can be exempted, what about electric motor driven machines which may or may not powered from the mains? I am not thinking of the machines which have radio transmitters. FCC response You are correct, heavy machines, such as cranes, excavators are not designed for the purpose of transporting items or people,. The digital logic within the equipment, does not qualify as transportation vehicles for the 15.103 exemption. This equipment when transported is transported by other transport vehicles (trucks) between locations where they are temporally stationed for a period of time for their purpose to perform other specific task. In addition (in the case of cranes) could be connected to the power mains, which also disqualifies the equipment. In most cases the large Heavy machines would be used beyond 200 feet of a residential area and can be considered Class A. Manufactures should note that independent of exemptions or Class A or B, all Part 15 equipment is subject to the general conditions of operation in 15.5 and 15.29 which would require the equipment to be turned off in case of any interference issues. </QUOTE> Regards, Tom -- Tomonori Sato <[email protected]> URL: http://homepage3.nifty.com/tsato/ - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
