Replacing the Battery
A low battery is indicated by a dim display, even if contrast is adjusted, or by
failure of figures to appear on the display immediately after you turn on the
calculator. If this happens, replace the battery with a new one.
Important: Removing the battery will cause all of the calculator’s memory
contents to be deleted.

minus (–) ends are facing correctly.
