Monitor care
Always remove the plug from the AC outlet when clean-
ing the monitor.

the cabinet and control panel.
If they are very dirty, apply neutral detergent to a damp-
ened 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.)

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.
