Attention
• Do not exert strong pressure to the surface of the display screen. You may break the LCD panel.
• Do not place heavy objects on top of this product. They may damage the display.
• Do not touch the display screen with your fingers. Fingerprints and oil stains may remain on the 
screen surface. They are difficult to wipe off.
• The display is heavy. Ask the help of others if you cannot carry it by yourself.
• When leaving your office for a long vacation, always unplug the power cords from the main

LCD considerations
The liquid crystals in the display panel contain several irritants. If the panel is damaged or broken, 
do not let the liquid come in contact with your skin, eyes, or mouth. If you do come in contact with 
the liquid, flush the affected part with running water for at least 15 minutes. If any symptom remains, 
consult a doctor.
The fluorescent lamp in the liquid crystal display (LCD) contains mercury (50 mg. (0.002 oz.) 
maximum). Do not place in trash that is disposed of in landfills. Dispose of it as required by local 
ordinances or regulations.
Considerations on the display resolution
This display is able to display characters, graphics, and pictures at high resolution. When you 
connect this display to a PC with a high resolution (3840 x 2400), the characters will be displayed at 
1/4 the normal size. Do not continue to operate the PC at this character size. You can spoil your eyes. 
Change the character size to a bigger size or the resolution to a lower resolution on the operating 
system or application.
Operating considerations
To ensure comfortable operation of the display, follow the instructions below:
• Place the display in front of you for easy viewing.
• Place the display at a comfortable distance (50 –60 cm) (19 – 24 in.) from you.
• Tilt the display so that top of the display is at your eye level.
• Adjust the angle of the tilt so that there is no reflection of light and objects. If necessary, turn off 
the light or lower its luminescence. If near a window, close the curtains or pull down the blind to 
cut the sunlight.
• Adjust the screen brightness.
• Use a chair with a high-reclining and sit deep into it.
• Operating on the screen for long hours can cause fatigue and eyestrain. Divert your eyes from the 
screen for short intervals during operation, and take short rests.
