Brian:
I should let some other ex-FCC guys comment on this authoritatively, but I can toss in my observations too. There is a voluntary EMC standard for vehicles in the USA, but RV's are built with a split responsibility. A chassis maker (like Ford or Freightliner of Mercedes) builds a chassis (likely under the EMC standard) and then sells it to an RV coach builder (who either hasn't heard of the standard or ignores it). Yachts are a bit different; I think that there is a body (NMEA, National Marine Electronics Association ?) that sets some standard for the marine environment, but they seem to be focused on data interoperability more than traditional EMC. Another interesting angle is that RV's and yachts are rather expensive, so the people who own them tend to have a bit more personal resources available to mitigate their own EMC problems. And lastly, if the FCC doesn't hear complaints, then they probably have enough obligations already and likely wouldn't want to extend into larger areas of responsibility. Maybe. Anyway, God doesn't like trailer parks, as he always routes His tornados through them.

So is a harbor considered a residential area which would require Class B computing devices among other electronic devices?? A harbor is really like a trailer park. How does the FCC consider motor homes or trailers? Interesting Topic.

However, I thought I'd share an interesting recent experience with you, for your information. I sent a KDB to the FCC about a boat (luxury yacht) that had a USB port on the dashboard (I'm not sure if boat users employ the terminology 'dashboard'? I guess I mean the place where the 'driver' stands, to guide the 'pointy end' of the boat). J The USB port on the dashboard was there to allow a person to use a laptop, to update the software to the boat's GPS and navigation systems. The FCC confirmed that the GPS etc. within the boat's dashboard would require a DoC, because it becomes a Class B computer peripheral when you take a laptop onto the boat and plug it into the dashboard. I suspect this probably comes from the history of the Class B or A decision, with regard to proximity to television receivers. Being a luxury yacht, it had many television receivers. I confess, I was surprised. Michael.

Test required for verification process is OK (No harmful interference at Industrial environment). This device has been tested and found to comply with the limits for a Class A digital device. These limits provide reasonable protection against harmful interference when equipment is operated in a commercial environment. **************************************************************************** ********************************************* I know the following from FCC: Verification: allows you to use an FCC listed lab or you can use your own lab. * Both require you to maintain test records in a format specified in the rules: Verification:- Retention of Records are in 2.955 of the rules. 1. No additional description of measurement facilities is required if using a FCC listed lab under 2.948 (1 ) (ii) 2.

Do you think we just needs Verification for this industrial Class A device? Please advise. Thank you for your help.
