Thanks, Paul, for your helpful reply - in language I could understand!! I tried the suggestions, and it's still red. I can learn to live with it, but do you think this might be an indicator that in the future other problems will turn up? I haven't checked to see if there's a dealer nearby (I live in a small town in rural Alabama, USA), but I can always send it somewhere, I guess. Thanks again. I hesitated to find a forum and post because I figured I wouldn't understand the answer, but I'm glad I did.
