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.
Place the display near or over a radiator or heat source.
Main power breaker is the power cord and this breaking device must be located at
a location where it is easy to operate.
Do not rub or strike the Active Matrix LCD with anything hard as this may scratch,
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.
Some dot defects may appear as Red, Green or Blue spots on the screen.
However, this will have no impact or effect on the display performance.
If possible, use the recommended resolution to obtain the best image quality for
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.
Leaving a fixed image on the screen for a long time may cause damage to the
screen and cause image burn-in. Make sure to use a screen saver on the product.
Burn-in and related problems are not covered by the warranty on this product.
On Cleaning
Unplug the display before cleaning the face of the display screen.
Use a slightly damp (not wet) cloth. Do not use an aerosol directly on the display
screen because over-spraying may cause electrical shock.
On Repacking
Do not throw away the carton and packing materials. They make an ideal
container in which to transport the unit. When shipping the unit to another
location, repack it in its original material.
On Disposal
The fluorescent lamp used in this product contains a small amount of mercury.
Do not dispose of this product with general household waste.
Disposal of this product must be carried out in accordance to the regulations of
your local authority.
