5.3 Display Contrast Control
This function serves for the contrast adjustment of the LC display. The last adjustment is
stored and does not have to be repeated at every system start.
A pattern is shown by means of which the
display can be adjusted to the optimum
contrast. Use the functional keys to modify
the contrast upon request:
Press key "OK" to store the adjusted
contrast value and to quit the function.
During normal LMI operation the display
contrast can be adjusted too by pressing
F2 (brighten display) or
F3 (darken display).
