PRECAUTIONS
Cautions When Using
Use only the power cord supplied with the LCD display.
The power outlet should be installed near the LCD display and be easily accessible.
If an extension cord is used with the LCD display, ensure that the total current consumption
plugged into the power outlet does not exceed the ampere rating.
Do not allow anything to rest on the power cord. Do not place the LCD display where the power
cord may be stepped on.
If the LCD display will not be used for an indenite period of time, unplug the power cord from
the power outlet.
To disconnect the power cord, grasp and pull by the plug head. Do not tug on the cord; doing
so may cause re or electric shock.
Do not unplug or touch the power cord with wet hands.
WARNING:
Unplug the power cord from the power outlet and refer to qualied service personnel under

PRECAUTIONS
Cleaning and Maintenance
Do not attempt to service the LCD display yourself, refer to qualied 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.
