Active Menu consists of two interfaces: a) Main Menu (JobMenu.xml) and b) System Menu (SystemMenu.xml). You can find those XML files at \Program Files\CASIO\ActiveMenu\ENV\INI\.
Generally speaking, the end-user works with the Main Menu, while the System Menu is intended to be used by administrators. When Active Menu is launched, it goes to the Main Menu. You can switch to the System Menu by executing the ActiveMenuSwitcher.exe at \Program Files\CASIO\ActiveMenu.
