Precaution

On Safety

• Operate the unit on 100-240 V AC only.
• The nameplate indicating operating voltage, etc. is

located on the AC adaptor.

• Should any solid object or liquid fall into the cabinet,

unplug the unit and have it checked by qualified
personnel before operating it any further.

• Unplug the unit from the wall outlet if it is not to be

used for several days or more.

• To disconnect the AC power cord, pull it out by

grasping the plug. Never pull the cord itself.

• The socket-outlet shall be installed near the equipment

and shall be easily accessible.

On Installation

• Prevent internal heat build-up allowing adequate air

circulation.
Do not place the unit on surfaces (rugs, blankets, etc.)
or near materials (curtains, draperies) that may block
the ventilation holes.

• Do not install the unit near heat sources such as

radiators or air ducts, or in a place subject to direct
sunlight, excessive dust, mechanical vibration or
shock.

• Do not place the monitor near equipment which

generates magnetism, such as a transformer or high
voltage power lines.

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 screen is made with high-precision

technology and more than 99.99% of the picture
element is intact. However, some of the picture
element may not appear or some of the picture element
may appear constantly.

• 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 monitor’s screen. Do

not place a heavy object on the LCD monitor’s 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.

• If a still picture is displayed for a long time, a residual

image may appear. The residual image will eventually
disappear.

• The screen and the cabinet become warm during

operation. This is not a malfunction.

About the Fluorescent Tube

• A specially designed fluorescent tube is installed as

the lighting apparatus for this unit. If the LCD screen
becomes dark, unstable or does not turn on, consult
your Sony dealer.

On Cleaning

Before cleaning
Be sure to disconnect the AC power cord from the AC
outlet.

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.
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 or the coating may come off.
