Operation and adjustment of the display
This section of the manual explains all the functions and calibration of the display.
For instance the calibration of the LCD monitor is carried out with the help of the OSD (On Screen
Display) and the four pushbuttons. These four pushbuttons are used to navigate the menus and
set parameters in the OSD menus.
You have the choice of using the four pushbuttons on the rear of the display or you can use the
arrow keys on the keyboard ( CHALLENGER KB ).
To activate the four arrow keys on the keyboard that are used to control the OSD, the key
combination
Ctrl OSD must be entered. In other words, the Ctrl key and the keys O, S and D must
be pressed at the same time. In this mode of operation the keyboard stops sending data to the
PC. The functions now allocated to the four arrow keys are described in the table below. To revert
to normal keyboard operation, simply press the Esc key.
