I had the same problem, sent email to dobeck(the manufacturer) reply was
"FMF PP bought after Aug, 2010 for the WR250R will not scroll after engine start up. Yes our Green looks yellowish to some people and yellow is a redish orange. From what you have stated on what you observed the unit is working correctly. "
I watched the video above, took a few goes but I eventually got the hang of it, you just have watch for the sequence of the lights, good luck
