dampened soft cloth, wring it out well and wipe
away grime.

dust from the surface of the LCD panel. (A soft
cloth such as gauze or that used for lens cleaning
is suitable.)

cleaner, etc, as this could lead to color change or
change in shape.

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, it may be necessary to
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.
