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.

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.)

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.

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

The monitor is based on VESA DPMS (Display
Power Management Signaling).
To activate the monitor's Power Management func-
tion, both the video card and the computer must
conform to the VESA DPMS standard.

This monitor supports the VESA DDC (Display Data
Channel) standard.
DDC is a signal standard for carrying out Plug &
Play functions on the monitor or PC. It transfers
information such as degree of resolution between
the monitor and PC. You can use this function if your
PC is DDC compliant and if it is set so that it can
detect the Plug & Play monitor.
There are many varieties of DDC due to the differ-
ences between systems. This monitor works with
DDC1 and DDC2B.
