I also want to thank people who have contributed to this thread - truly expert advice. My problem is that living in the UK I know of no-one who has the full DCS system - the problem is the different electricity supply, which makes the Remote Commander so attractive here as it can be run off my 20v supply to the track.
So if anyone knows of anyone in the UK with DCS so I can try a factory re-set ..... I'd be very interested!
Best wishes to all
David
