Question about Casio CFX 9850GA Plus Calculator
OK, changed batteries both at the same time, I know, didn't see that part. nor do I have an instruction manual. When I turn it on, all I get is a screen with list 1, list 2, list and 4, then 1,2,3,4,5 in the viertical column, In number 1 is 2.2266, at the very bottom right is a row of 2's. I can't get it to do anything but boot to this screen. Your help would be appreciated. Paul Shea
