Precautions
■ The liquid inside the LCD contains an irritant. If some of this liquid makes contact
with your skin, immediately wash the affected area with running water for a mini-
mum of 15 minutes.
■ If the liquid from inside the LCD gets into your eyes, rinse your eyes with running
water for 15 minutes and then consult a doctor.
LCD characteristics
■ The tone and brightness of each MB-Panel Display is an individual characteristic
and can be slightly different from one display to the other.
■ At some contrast settings or with some images, flickering or differences in the
brightness levels may appear.
■ When viewing an MB-Panel display from an angle which is outside of the specified
viewing angle, colours could appear differently, and depending on what is being
displayed, may not be visible at all. The viewing angle for the MB-Panel Display is
as follows: Draw a line perpendicular to the display, from the center of the display.
From the center chapter using this line as a reference, you can go 40 ° in each
direction.
■ On some MB-Panels with a monochrome display, you may see an isolated black
or white spot. This happens when a pixel stays permanently on (white) or perma-
nently off. (black). A pixel with this state may or may not been seen depending on
what is being displayed.
■ Displaying the same image for a long period of time could result in traces of that
image appearing when another image is displayed. To correct this, turn off the unit
for at least 10 seconds and then power the unit back on.
■ From around the sides of some screen images, lines or streaks may appear. (Also
known as «Crosstalk»)
Note: If the unit has just been powered up, let it stabilize for 30 minutes. After this
adjust the contrast. This should minimize if not eliminate the lines/streaks com-
pletely.
Example of Crosstalk
The lines/streaks coming
from around the edges of
the + / - Buttons is referred
to as «Crosstalk»
