Monitor care and repair
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 they are 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.

If the monitor will not be used for a long period of
time, be sure to remove the power plug from the
AC outlet.

life span.

replace the florescent tube unit. 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.
