Chapter 5. The Firmware Upgrade Utility
If you enabled Check Firmware Upgrade, the Utility compares the device's firmware level with that of the upgrade files. If it finds that the device's version is the same, or higher, it brings up a dialog box informing you of the situation and gives you the option to Continue or Cancel.
If you didn't enable Check Firmware Upgrade, the Utility installs the upgrade files without checking their version level.
While a device group is being upgraded, the background behind its name changes to blue and blinks on and off to indicate that upgrading is in progress.
A green background behind the device name indicates that it will be upgraded.
As the Upgrade proceeds, status messages appear in the Status Messages panel, and the progress toward completion is shown on the Progress bar.
The KH2508 / KH2516 OSD also displays the progress toward completion in its own progress bar.
