Cleaning and Maintenance
Do not attempt to service the LCD display yourself, refer to qualified service personnel.
Opening or removing the covers may expose you to dangerous voltage or other risks.
Notice for the LCD Display
In order to maintain the stable luminous performance, it is recommended to use low brightness setting.
Due to the lifespan of the lamp, it is normal that the brightness quality of the LCD display may decrease
with time.
When static images are displayed for long periods of time, the image may cause an imprint on the LCD
display. This is called image retention or burn-in.
To prevent image retention, do any of the following:
• Set the LCD display to turn off after a few minutes of being idle.
• Use a screen saver that has moving graphics or a blank white image.
• Switch desktop backgrounds regularly.
• Adjust the LCD display to low brightness settings.
• Turn off the LCD display when the system is not in use.
Things to do when the LCD display shows image retention:
• Turn off the LCD display for extended periods of time. It can be several hours or several days.
• Use a screen saver and run it for extended periods of time.
• Use a black and white image and run it for extended periods of time.
There are millions of micro transistors inside the LCD display. It is normal for a few transistors to be
damaged and to produce spots. This is acceptable and is not considered a failure.
