Important Precautions

On Installation

Do not allow anything to rest upon or roll over the power cord, and do not place
the display where the power cord is subject to damage.

Do not use this display near water such as near a bathtub, washbowl, kitchen
sink, laundry tub, in a wet basement, or near a swimming pool.
Displays are provided with ventilation openings in the cabinet to allow the release
of heat generated during operation. If these openings are blocked, built-up heat
can cause failures which may result in a fire hazard. Therefore, NEVER:

Block the bottom ventilation slots by placing the display on a bed, sofa, rug, etc.
Place the display in a built-in enclosure unless proper ventilation is provided.
Cover the openings with cloth or other material.

mar, or damage the Active Matrix LCD permanently.

Do not press the LCD screen with your finger for a long time as this may cause
some afterimages.

your LCD display. If used under any mode except the recommended resolution,
some scaled or processed images may appear on the screen. However, this is
characteristic of the fixed-resolution LCD panel.

screen because over-spraying may cause electrical shock.
