About the LCD Display Panel

• Although the LCD display panel is made with high-
precision technology, black dots may appear or bright
points of light (red, blue, or green) may appear
constantly on the LCD screen. And a color shade or
bight shade may appear according to a viewing angle.
These are structural properties of the LCD panel and
are not malfunctions.
• The LCD panel fitted to this unit is manufactured with
high precision technology, giving a functioning pixel
ratio of at least 99.99%. Thus a very small proportion
of pixels may be "stuck", either always off (black),
always on (red, green, or blue), or flashing. In
addition, over a long period of use, because of the
physical characteristics of the liquid crystal display,
such "stuck" pixels may appear spontaneously. These

On cleaning the monitor
A material that withstands disinfection is used for the
front protection plate of the medical use LCD monitor.
The protection plate surface is especially treated to
reduce reflection of light. When solvents such as
benzene or thinner, or acid, alkaline or abrasive
detergent, or chemical cleaning cloth are used for the
protection plate surface/monitor surface, the
performance of the monitor may be impaired or the
finish of the surface may be damaged. Take care with
respect to the following:
• Clean the protection plate surface/monitor surface
with a 50 to 70 v/v% concentration of isopropyl
alcohol or a 76.9 to 81.4 v/v% concentration of
ethanol using a swab method. Wipe the protection
plate surface gently (wipe using less than 1 N force).
• Stubborn stains may be removed with a soft cloth such
as a cleaning cloth lightly dampened with mild
detergent solution using a swab method and then clean
using the above chemical solution.
Never use solvents such as benzene or thinner, or acid,
alkaline or abrasive detergent, or chemical cleaning
cloth for cleaning or disinfection, as they will damage
the protection plate surface/monitor surface.
• Do not use unnecessary force to rub the protection
plate surface/monitor surface with a stained cloth.
