When in the main screen at the top is the list of depts. You push one and the list of category's shows up on the left side of the screen. When you push any one of the category's the whole list does not show up on the screen. The up and down arrows are not lit saying that is all there is. When you do push a category that the arrows do light up they don't work - meaning they don't bring up more of the list.
