Recommendation to Use more than
One Unit
As problems can occasionally occur for the monitor,
when the monitor is used for safety control of personnel,
assets or stable picture, or for emergencies, we strongly
recommend you use more than one unit or prepare a
spare unit.
LCD image display
Due the physical characteristics of LCD panels, there
may be a decrease in brightness or change in color
temperature over a long period of use. These problems
are not a malfunction.
In addition, these occurrences will not affect recorded
data.
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 display, such
“stuck” pixels may appear spontaneously. These
problems are not a malfunction.
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 push or scratch the LCD screen. Do not place
a heavy object on the LCD screen. This may cause the
screen to lose uniformity.
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.
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.
Do not damage the panel with a sharp object. The glass
may crack due to the damage.
On 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 display 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.
To prevent any of the above issues, we recommend
reducing brightness slightly, and to turn off the power
whenever the unit is not in use.
On Burn-in
For LCD panel, permanent burn-in may occur if still
images are displayed in the same position on the screen
continuously, or repeatedly over extended periods.
Images that may cause burn-in
Masked images with aspect ratios other than 17:9 for
the LMD-X310MD and 16:9 for the LMD-X550MD
Color bars or images that remain static for a long time
Character or message displays that indicate settings or
the operating state
To reduce the risk of burn-in
Turn off the character displays
Press the MENU button to turn off the character
displays. To turn off the character displays of the
connected equipment, operate the connected
equipment accordingly. For details, refer to the
operation manual of the connected equipment.
Turn off the power when not in use

environment and the internal temperature rises, an error
is displayed on the screen. When the error is displayed,
contact an authorized Sony dealer.
On Moisture Condensation
If the unit is suddenly taken from a cold to a warm
location, or if ambient temperature suddenly 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
condensation clears before operating the unit. Operating
the unit while condensation is present may damage the
unit.

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 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 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.
