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.  
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.  
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.

How to Install the VESA Standard wall mounting  
This monitor meets VESA-compliant mounting interface pad  
specifications.  
1. Please the monitor on a piece of cloth or other soft surface with the  
front side facing downward and remove the rear cap.  
2. Slide off the lower section of the cover  
base with two hands as shown in the  
picture.  
3. Separate the stand base using a  
screwdriver as shown in the picture.  
4. Install the VESA standrad wall mounting.  
VESA wall mounting  
Connected to another object (stand type  
and wall-mounted type. This monitor  
accepts a VESA-compliant mounting  
interface pad.-optional)

Making use of USB (Universal Serial Bus) - Optional  
USB (Universal Serial Bus) is an innovation in connecting your different  
desktop peripherals conveniently to your computer. By using the USB, you will  
be able to connect your mouse, keyboard, and other peripherals to your display  
instead of having to connect them to your computer. This will give you greater  
flexibility in setting up your system. USB allows you to connect a chain of up to  
120 devices on a single USB port; and you can “hot” plug (attach them while  
the computer is running) or unplug them while maintaining the Plug and the  
Plug auto detection and configuration. This display has an integrated BUS-  
powered USB hub, allowing up to 2 other USB devices to be attached it.  
USB connection  
1. Connect the upstream port of the display to the downstream port of the USB  
compliant PC or another hub using the USB cable. (Computer must have a  
USB port)  
2. Connect the USB compliant peripherals to the downstream ports of the  
display.  
This is a simplified representation  
of rear view.  
USB upstream Port  
To USB downstream port of  
the USB compliant PC or  
another hub cable  
USB downstream Port  
connect the cables from USB  
compliant peripherals-such as  
keyboard, mouse, etc  
NOTE  
To activate the USB hub function, the display must be connected to a USB compliant PC(OS)  
or another hub with the USB cable(enclosed).  
When connecting the USB cable, check that the shape of the connector at the cable side  
matches the shape at the connecting side.  
Even if the display is in a power saving mode, USB compliant devices will function when they  
are connected the USB ports(both the upstream and downstream) of the display.
