X
Recommendation to use more than one unit
As problems, can occasionally occur, when the monitor is used under critical conditions, we
strongly recommend you use more than one unit or prepare a spare unit for replacement.

About the LCD Display Panel
•
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 dis-
play, such “stuck” pixels may appear spontaneously. These problems are not a malfunc-
tion.
•
Do not leave the LCD screen facing the sun as it can damage the LCD screen. Take care
when you place the unit by a window.
•
Do not store the monitor FACE DOWN.
•
Do not push or scratch the LCD screen.
•
Do not place a heavy object on the LCD screen. This may cause the screen to lose unifor-
mity.
•
If the unit is used in a cold place, a residual image may appear on the screen. This is not a
malfunction. When the monitor becomes warm, the screen returns to normal.
•
The screen and the cabinet become warm during operation. This is not a malfunction.
X
Images that may cause burn-in
•
Masked / boarded images with aspect ratios other than 16:9
•
Color bars or images that remain static for a long time
•
Continuous characters or messages displaying on the screen
X
To reduce the risk of burn-in
Turn off the character displays from connected equipment.

About the screen protect panel
The screen protect panel is made of toughened glass, but there is a possibility that it may
crack.
•
Handle with care. Avoid strong impact, such as dropping from a high place or an object
swinging into it.
•
Do not scratch the panel with a sharp object or place it in harm’s way.
X
A long period of use
•
Due to the characteristics of LCD panel, displaying static images for extended periods, or
using the unit repeatedly in a high temperature/high humidity environments may cause
image smearing, burn-in, areas of which brightness is permanently changed, lines, or a
decrease in overall brightness.
•
In particular, continued displaying of an image smaller than the monitor screen, such as in
a different aspect ratio, may shorten the life of the unit.
•
Avoid displaying a still image for an extended period, or using the unit repeatedly in a high
temperature/high humidity environment such an airtight room, or around the outlet of an
air conditioner.
X
Moisture condensation
If the unit is suddenly taken from a cold to a warm location, or if ambient temperature sud-
denly rises, moisture may form on the outer surface of the unit and/or inside of the unit. This
is known as condensation. If condensation occurs, turn off the unit and wait until the conden-
sation clears before operating the unit. Operating the unit while condensation is present may
damage the unit.
X
Before cleaning
Be sure to disconnect the AC power cord from the AC outlet.
X
Cleaning the monitor
A material that withstands disinfection is used for the front protection plate of the healthcare
use LCD monitor. The protection plate surface is specially 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 re-
spect 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 damp-
ened 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. The protection plate surface/monitor surface may be scratched.
•
Do not keep the protection plate surface/monitor surface in contact with a rubber or vinyl
resin product for a long period of time. The finish of the surface may deteriorate.
