Monitor care

Always remove the plug from the AC outlet when
cleaning the monitor.
Cabinet and control panel section
Use a soft dry cloth to lightly wipe away any grime from
the cabinet and control panel.
If very dirty, apply neutral detergent to a dampened soft
cloth, wring it out well and wipe away grime.
LCD panel section
Use a soft dry cloth to lightly wipe away dirt and dust
from the surface of the LCD panel. (A soft cloth such as
gauze or that used for lens cleaning is suitable.)
CAUTION!
- Never use thinner, benzine, alcohol, glass cleaner,
etc, as this could lead to color change or change in
shape.
- Never scratch the monitor with anything hard or
apply strong pressure as this could leave marks or
result in malfunction.

Storage

be sure to remove the power plug from the AC outlet.

Do not leave the monitor in contact with rubber or plastic
items for long periods of time as this could lead to color

Troubleshooting

If you think the monitor may be faulty, please check the
following points before taking it to be repaired.
If afterwards it still does not work, please contact the
shop where you purchased the monitor or your nearest
Sharp authorized Service Center.
The monitor's florescent tubes have a limited life
span.
- If the screen darkens, persistently flickers or
does not light up, the florescent tube unit may
need replacement. Please inquire at the shop
where you purchased the monitor or your
nearest Sharp authorized Service Center. (Never
attempt this replacement on your own.)
- In the initial period of use, due to the
characteristics of florescent tubes the screen
may flicker. (This is not a malfunction.) Should
this happen, check by first turning off the power,
then turning it on again.
