Preface
LCD Usage and Handling
• The brightness of the LCD screen will depend on the screen's current display
and the LCD's contrast adjustment. Any brightness variations that result are
normal for LCD displays.
• There are minute grid-points (Dark or Light points) on the LCD surface. These
points are not defects and are a part of the DU panel’s design.
• The displayed color will look different when viewed from an angle outside the
specified view angle. This is also normal.
• When installing this unit, be sure that the screen is viewable from within the
designated direction, otherwise the view angle will be effected.
• Displaying a single screen image for long periods of time can cause an afterim-
age to remain on the screen. To correct this, turn the unit OFF for 5 to 10
minutes, then ON again. This phenomenon is a common attribute of the LCDs,
and is not a defect. To prevent this effect, you can:
1) Use the Display OFF feature; if the same image is to be displayed for a long
period of time.
2) Change the screen display periodically to prevent the displaying of a single
image for a long period of time.
(For further information about LCD usage and handling, contact your local DU
distributor.)
Prior to Using the DU
After connecting the DU to the PL and setting up the PL's OS, you will need to
input the DU's screen settings and perform touch panel calibration.
