Preface
n n n n n About the GP's Display Panel
• The GP's currently displayed data, its voltage
affect the intensity of Contouring. (i.e, when some parts of the screen are
brighter than others, creating a wavelike pattern)
• There are minute grid-points (dark and light) on the Display Panel's surface.
This is part of the GP's design and not a defect.
• Shadows may appear at the top of the LCD. This is normal for an LCD display.
• Sometimes the display area may look as if the display colors have changed.
This is a common attribute of LCD's and is not a defect.
• Displaying a single image for long periods can cause an afterimage to remain
when the display is changed to another screen.
To prevent this effect:
• Write "FFFFh" in the System Data Area's "Screen Display Off" address
*1 If the GP's voltage is at the very low end of its allowable range, it may effect the
intensitly of contouring.

not all entered, the correct word address may be different from those given here.
