mended small
amount of cleaner by using a soft cloth to polish. Do not force the LCD \
area but rub softly.
If excessive force is applied, you may stain it.  If you are not satisfied with the picture quality, you can get better q\
uality of picture by
performing the  Auto Adjustment  function in display screen that is appeared as window
termination button is pressed.
If theres still noise after the automatic adjustment, use the  Fine/Coarse adjustment func-
tion.  When viewing a fixed screen for an extended period of time, a residual \
image or blur-
riness may appear.
Change the mode to energy save or set a screensaver to move the picture \
when you need
to be away from the monitor for an extended period of time.
PRODUCT INFORMATION (Image Retention Free) LCD Monitors and TVs may have image retention when switching from one im\
age to another espe-
cially after displaying a stationary image for a long time.
This guide is to demonstrate correct usage of LCD products in order to p\
rotect them from Image
retention.  Warranty
Warranty does not cover any damage caused by image retention.
Burn-in is not covered by the warranty.  What is Image retention ?
During normal operation of a LCD panel, pixel image retention doesnt oc\
cur. However, if
the same image is displayed for a long time, a slight difference in elec\
tric charge accumu-
lates between the two electrodes which encase the liquid crystal. This m\
ay cause the liquid
crystal to build up in a certain areas of the display. Thus, the previou\
s image is retained 49
