About the built-in stereo speakers
Be sure to keep magnetic recording equipment,
tapes, and floppy discs away from the speaker’s
opening as the speakers generate a magnetic
field. This magnetic field may affect data stored
on magnetic tapes and discs.
Handling the headphones
Be sure to remove the headphones before
moving away from the display. If the
headphone cord is pulled away from the display
abruptly, injury or damage may occur.
Note on the LCD (Liquid Crystal
Display)
Please note that the LCD screen is made with
high-precision technology. However, black
points or bright points of light (red, blue, or
green) may appear constantly on the LCD
screen, and irregular colored stripes or
brightness may appear on the LCD screen. This
is not a malfunction.

Maintenance
■
Be sure to unplug the power cord from the
power outlet before cleaning your display.
■
Clean the LCD screen with a soft cloth. If you
use a glass cleaning liquid, do not use any type
of cleaner containing an anti-static solution or
similar additive as this may scratch the LCD
screen’s coating.
■

with a soft cloth lightly moistened with a mild
detergent solution, then dry off with a soft
cloth. Do not use any type of abrasive pad,
scouring powder, or solvent, such as alcohol or
benzine.

Do not rub, touch, or tap the surface of the
screen with sharp or abrasive items such as a
ballpoint pen or screwdriver. This type of
contact may result in a scratched LCD display

coating degradation may occur if the display is
exposed to volatile solvents such as insecticide,
or if prolonged contact is maintained with
rubber or vinyl materials.
