PRECAUTIONS
Cleaning and Maintenance
Use a soft cloth to clean the glass surface and the housing.
The display can be cleaned using a cloth moistened with 95% ethyl alcohol.
Do not rub or tap the surface of the glass with sharp or abrasive items such as a pen or
screwdriver. This may result in scratching the surface of the glass.
Do not attempt to service the LED-backlit display yourself, refer to qualified service personnel.
Opening or removing the covers may expose you to dangerous voltage or other risks.
Notice for the LED-Backlit 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 LED-backlit display may
decrease with time.
When static images are displayed for long periods of time, the image may cause an imprint on the LED-
backlit display. This is called image retention or burn-in.
To prevent image retention, do any of the following:
• Set the LED-backlit 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 LED-backlit display to low brightness settings.
• Turn off the LED-backlit display when the system is not in use.
Things to do when the LED-backlit display shows image retention:
• Turn off the LED-backlit 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.
When the LED-backlit display is moved from one room to another or there is a sudden change from low to
high ambient temperature, dew condensation may form on or inside the glass surface. When this happens,
do not turn on the LED-backlit display until the dew disappears.
Due to humid weather conditions, it is normal for mist to form inside the glass surface of the LED-backlit
display. The mist will disappear after a few days or as soon as the weather stabilizes.
There are millions of micro transistors inside the LED-backlit display. It is normal for a few transistors to be
damaged and to produce spots. This is acceptable and is not considered a failure.
