Using Custom Test Image Packs

The 780/780AH provides licensed image packs for certain sets of test images. You need to have a license key
to use these custom test image packs. You can arrange to get access to them by contacting Quantum Data
customer support at: http://www.quantumdata.com/support.
When you purchase an image pack it appears as an icon at the end of the list of Test Patterns. A sample
screen is shown below (Philips1, ChinaRes, Master). You simply select one of the test patterns (e.g. ChinaRes
in the screen example below). They will take a few seconds to load. They will load at the resolution of the
format that you have selected.
