Image Persistence:
Image persistence exists, when a residual or “ghost” image of a previous image remains visible on the
screen. Unlike with CRT monitors, image persistence on LCD monitors is not permanent, but constant images being displayed
for a long period of time should be avoided.
To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image
was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image.
NOTE:
As with all personal display devices, NEC DISPLAY SOLUTIONS recommends using a moving screen saver at regular
intervals whenever the screen is idle or turning off the monitor when not in use.
Maintenance:
This display is factory calibrated for diagnostic imaging, in accordance with DICOM Part 14. To ensure constant
visual quality over the life of the display, the recommended time interval to re-calibrate these models is 12 months.
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 during normal operation, allow 20 minutes for the display
to warm up. For re-calibration and DICOM conformance tests, please allow at least
60 minutes to achieve best results.
•
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 40 cm (15.75 inches) and no further away than
70 cm (27.56 inches) from your eyes. The optimal distance is 50 cm (19.69 inches).
•
Rest your eyes periodically by focusing on an object at least 6 m (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.
•
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.
•
Avoid displaying fi xed patterns on the monitor for long periods of time to avoid image persistence (after-image effects).
•
Get regular eye checkups.
Cleaning the LCD Panel
•
When the LCD is dusty, please gently wipe with a soft cloth.
•
Please do not rub the LCD panel with hard or coarse material.
•
Please do not apply pressure to the LCD surface.
•
Please do not use OA cleaner as it will cause deterioration or discoloration on the LCD surface.
Cleaning the Cabinet
•
Unplug the power supply cord from the wall outlet.
•
Gently wipe the cabinet with a soft cloth.
•
To clean the cabinet, dampen the cloth with a neutral detergent and water, wipe the cabinet and follow with a dry 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 time. These types of fl uids and fabrics can cause the paint to deteriorate, crack or peel.
