8PRECAUTIONS
LCD Panel
In order to suppress the luminosity change by long-term use and to
maintain the stable luminosity, use of a monitor in lower
brightness is recommended.
The screen may have defective pixels. These pixels may appear as
slightly light or dark area on the screen. This is due to the
characteristics of the panel itself, and not the product.
The backlight of the LCD panel has a fixed life span. When the
screen becomes dark or begins to flicker, please contact your
dealer.
Do not press on the panel or edge of the frame strongly, as this
may result in damage to the screen. There will be prints left on the
screen if the pressed image is dark or black. If pressure is
repeatedly applied to the screen, it may deteriorate or damage
your LCD panel. Leave the screen white to decrease the prints.
When the screen image is changed after displaying the same image
for extended periods of time, an afterimage may appear. Use the
screen saver or timer to avoid displaying the same image for
extended periods of time.
When the monitor is cold and brought into a room or the room
temperature goes up quickly, dew condensation may occur inside
and outside the monitor. In that case, do not turn the monitor on
and wait until dew condensation disappears, otherwise it may
cause some damages to it.
Do not scratch or press on the panel with any sharp objects, such
as a pencil or pen as this may result in damage to the panel. Do
not attempt to brush with tissues as this may scratch the LCD
panel.
