There should be a button on the back which will reset it for you...
otherwise take the batteries out and put them back in...
the busy will eventually go away if you just leave it long enough though!

Functions don't work


The presence of the Fat arrows to the left of the Y1, Y2,etc = functions means that the Transfrm application is running. It takes over the graphing from the native OS.
You must uninstall it.
  1. Press [APPS] and scroll up to go to the bottom of the list of Applications.
  2. Highlight [ : Transfm] and press [ENTER]
  3. In the new screen with the heading "Transfm App" press the number that corresponds to uninstalling the Apps [1:Uninstall]
  4. Try to graph two simple functions Y1=X and Y2=2X.
  5. If these functions are graphed correctly you are back in business, if not turn Stats Plots off.
To turn Stat plots Off
Press [2nd][Y=] (Stat Plot)
Press [4:PlotsOff]
Press [ENTER]

If all else fails, Reset the Ram
Press [2nd][+] (MEM)
Press [7:Reset]
Press [1:All Ram]
Press [2:Reset]
Press [ENTER]
Press [CLEAR] to erase the "Ram Cleared" Message.
