• 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.

• Use the unit under an operating temperature of 0°C to 

35°C (32°F to 95°F).

• When the unit is installed on the rack or on a shelf, 

leave the space above and beneath the unit and 
between the unit and other equipment.

• Use a fan to cool the unit if the spaces are small.

First secure the upper screws and then the lower ones, as 
illustrated below.

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

consumption, etc. is located on the rear.

• 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.

• 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 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

• 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, the 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
