behaves strangely.	• Inability to make further downloads to the panel. May get "directory"
	errors, "graphics hierarchy" errors, etc.… indicating problems with
	the Flash memory.
	• Panel will not boot, or gets stuck on "AMX" splash screen.
	• Other problems also started after downloading to a new panel or a
	panel with a TPD4 file that takes up a considerable amount of the
	available Flash memory.
	Cause:
	• If the G4 device already contains a large enough file, subsequent
	downloads will take up more space than is available and could often
	corrupt the Flash memory. The demo file that typically ships with G4
	panels is one such file.
	Solution:
	• DO NOT download TPD4 files (of large size) over the demo pages, or
	any other large TPD4 file.
	• First download a small blank one page file to the G4 panel using the
	Normal Transfer option to send/download the page. Reboot the
	device, then do your regular file or firmware download.
