Changing the backup battery is simple enough. I need to know how to replace the battery which keeps the control panel lit up. My main screen just went dark but the system still works.

Rhonda, what type of keypad do you have? For many keypads, the backlight is powered through the main AC power. You may be in need of a replacement keypad.
