First request may have gone astray, so will try again. Came upon yours of 29 November 2014, and had copies made on transparencies. The color contrast on the transparencies could be better, though my color vision was always a problem, still is. Perhaps something can be done color wise, to assist old eyes. In any event, could you send operating instructions, please. Thanks for your attention.
