Hi! My first post here.
I have an issue with my recently acquired FX-4000p. It is in very nice shape, and everything seems to work well in Comp, SD, and LR modes, but not in Base-n mode.
When I enter a number (say 37) in decimal and subsequently switch to octal or binary view I get the expected 45 and 00100101, but hex view messes thing up -- I only get a row of eleven zeros. Switching back to dec, bin, or oct returns the proper number again.
After trying a little more in hex display it seems to me now that those zeros are leading zeros to the actual value, and that the 5 least significant numbers are not shown. So if I enter ABCDEFAB and press <EXE>, the display will show 00000000ABC. I cannot shift the display left or right, and calculations with the number shown give unusable results. Again, in dec, bin, oct everything works fine.
Is this a known bug or is the calculator simply defective? I haven't found anything mentioning this issue on line (yet).
