Recommended Use
CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR
CAN REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK THE
FOLLOWING WHEN YOU POSITION THE MONITOR:
• For optimum performance, allow 20 minutes for warm-up.
• Adjust the monitor height so that the top of the screen is at
or slightly below eye level. Your eyes should look slightly
downward when viewing the middle of the screen.
• Position your monitor no closer than 16 inches and no
further away than 28 inches from your eyes. The optimal
distance is 20 inches.
• Rest your eyes periodically by focusing on an object at
least 20 feet away. Blink often.
• Position the monitor at a 90° angle to windows and other
light sources to minimize glare and refl ections. Adjust
the monitor tilt so that ceiling lights do not refl ect on your
screen.
• If refl ected light makes it hard for you to see your screen, use an antiglare fi lter.
• Adjust the monitor's brightness and contrast controls to enhance readability.
• Use a document holder placed close to the screen.
• Position whatever you are looking at most of the time (the screen or reference material)
directly in front of you to minimize turning your head while you are typing.
• Get regular eye checkups.
Ergonomics
To realize the maximum ergonomics benefi ts, we recommend the following:
•
Use the preset Size and Position controls with standard signals
•
Use the preset Color Setting
•
Use non-interlaced signals with a vertical refresh rate between 60-75Hz
•
Do not use primary color blue on a dark background, as it is diffi cult to see and
may produce eye fatigue to insuffi cient contrast.
Cleaning the LCD Panel
• When the liquid crystal panel becomes dusty or dirty, wipe grntly with a soft cloth.
• Do not rub the LCD panel with coarse or hard material.
• Do not apply pressure to the LCD surface
• Do not use OA cleaner as it will cause deterioration or discoloration to the LCD sur-
face.
Cleaning the Cabinet
• Unplug the power supply.
• Dampen a soft cloth with water and a neutral detergent. Gently wipe the cabinet then
dry gently with a soft cloth.
NOTE: Many plastics are used on the surface of the cabinet. DO NOT clean with benzene,
thinner, alkaline detergent, alcoholic system detergent, glass cleaner, wax,
polish cleaner, soap powder, or insecticide. Do not touch rubber or vinyl to the cabinet
for a long period of time. These type of fl uids and fanrics can cause the paint to deteriorate
crack or peel.
