With the calculator off press and hold "g" then "enter" then "on. Release "on" then "g" then "enter". You will see "1.L 2.C 3.H" Press 1 to illuminate all LCD segments. Press 2 to display the checksum. Press 2 again to display the firmware version. Press 3 to perform the keyboard test. Press "on" to exit.
