Hi, indeed I reached the second phase of the process and just before attacking the black plastic cover of the rails, decided to maybe discuss the matter with ARC first.
The issue for me is that, living in France, the local rep tends to charge tremendous amounts of money for service, may the sums be justified or, mostly usually, may they not.
Question: when lifting the square metallic cover, from underneath it's left side, a 1 inch long piece of a plastic tube (like the one used for shrink or the edge of the cables that run through the unit) fell into the palm of my hand. Is it possible that this piece serves for anything or is just that the person who built the unit didn't finish the cleanup properly?...
Thanks again.
