• Use the supplied power cord. If you use a different power cord, 

be sure that it is compatible with your local power supply.
For the customers in the U.S.A.
If you do not use the appropriate cord, this monitor will not 
conform to mandatory FCC standards.

• Before disconnecting the power cord, wait at least 30 seconds 

after turning off the power to allow the static electricity on the 
screen’s surface to discharge.

• After the power is turned on, the screen is demagnetized 

(degaussed) for about 5 seconds. This generates a strong 
magnetic field around the screen which may affect data stored 
on magnetic tapes and disks placed near the monitor. Be sure to 
keep magnetic recording equipment, tapes, and disks away 
from the monitor.

Do not install the monitor in the following places:
• on surfaces (rugs, blankets, etc.) or near materials (curtains, 

draperies, etc.) that may block the ventilation holes

• near heat sources such as radiators or air ducts, or in a place 

subject to direct sunlight

• in a place subject to severe temperature changes
• in a place subject to mechanical vibration or shock
• on an unstable surface
• near equipment which generates magnetism, such as a 

transformer or high voltage power lines

• near or on an electrically charged metal surface

• Clean the screen with a soft cloth. If you use a glass cleaning 

liquid, do not use any type of cleaner containing an anti-static 
solution or similar additive as this may scratch the screen’s 
coating.

• Do not rub, touch, or tap the surface of the screen with sharp or 

abrasive items such as a ballpoint pen or screwdriver. This type 
of contact may result in a scratched picture tube.

• Clean the cabinet, panel and controls with a soft cloth lightly 

moistened with a mild detergent solution. Do not use any type 
of abrasive pad, scouring powder or solvent, such as alcohol or 
benzene.

When you transport this monitor for repair or shipment, use the 
original carton and packing materials.

This monitor can be adjusted within the angles shown below. To 
find the center of the monitor’s turning radius, align the center of 
the monitor’s screen with the centering dots on the stand.
Hold the monitor at the bottom with both hands when you turn it 
horizontally or vertically. Be careful not to pinch your fingers at 
the back of the monitor when you tilt the monitor up vertically.

The equipment should be installed near an easily accessible 
outlet.
