Do you have Owners manual? That would have the best explanation and directions to re-calibrate it.
D'oh! Of course it is in there. Thank you so much!
My seriously sincere congratulations to you for finding it !!! If you still have problems with calibrating it please post and maybe someone will have another idea. Thanks for the response!
