7-4 OSD FACTORY CONTROL
This should be adjusted by a technician or qualified repair personnel.
This monitor has two-adjustment modes.
One is for the user’s own adjustment and other is for factory adjustment.
But sometimes adjustments in the factory adjustment modes are needed for repair.
Caution: More precautions must be made in the factory adjustment mode compared to the
user mode, because after finishing adjustments in the factory mode, if wrong values have been
entered, you can not revert back to the old settings. At the user mode, if there are mistakes,
you can use the “RECALL” function (refer to 6-3 M item) to go back to the previous settings.
In factory mode, the “RECALL” function will only display your current settings.
A. Factory mode entering.
Press the “MODE” and “DOWN” key simultaneously until the OSD comes out as below.
The OSD of factory mode is the same format with user mode except for the color of the
bottom line. (User mode is blue; factory mode is red).
