Precaution

5

 

• Operate the unit only with a power source as specified 

in the “Specifications” section.

• A nameplate indicating operating voltage, power 

consumption, etc., is located on the rear panel.

• 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.

• Do not drop or place heavy objects on the power cord. 

If the power cord is damaged, turn off the power 
immediately. It is dangerous to use the unit with a 
damaged power cord.

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

used for several days or more.

• Disconnect the power cord from the AC outlet by 

grasping the plug, not by pulling the cord.

• The socket-outlet shall be installed near the equipment 

and shall be easily accessible.

• Allow adequate air circulation to prevent internal heat 

build-up.
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 in a location near heat sources 

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

• Bright or dark points of lights (red, blue or green) may 

appear on the LCD screen.  This is not a malfunction.  
The LCD screen is made with high-precision 
technology with more than 99.99 % of the picture 
elements intact.  However, some picture elements may 
not appear intermittently.

• 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, horizontal lines or 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.

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.

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

On cleaning the monitor
A material that withstands sterilization 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 sterilization, 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.
