PRECAUTIONS  
z Do not use the monitor near water, e.g. near a bathtub, washbowl, kitchen  
sink, laundry tub, swimming pool or in a wet basement.  
z Do not place the monitor on an unstable trolley, stand, or table. If the  
monitor falls, it can injure a person and cause serious damage to the  
appliance. Use only a trolley or stand recommended by the manufacturer  
or sold with the monitor. If you mount the monitor on a wall or shelf, use a  
mounting kit approved by the manufacturer and follow the kit instructions.  
z Slots and openings in the back and bottom of the cabinet are provided for  
ventilation. To ensure reliable operation of the monitor and to protect it  
from overheating, be sure these openings are not blocked or covered. Do  
not place the monitor on a bed, sofa, rug, or similar surface. Do not place  
the monitor near or over a radiator or heat register. Do not place the  
monitor in a bookcase or cabinet unless proper ventilation is provided.  
z The monitor should be operated only from the type of power source  
indicated on the label. If you are not sure of the type of power supplied to  
your home, consult your dealer or local power company.  
z The monitor is equipped with a three-pronged grounded plug, a plug with a  
third (grounding) pin. This plug will fit only into a grounded power outlet as  
a safety feature. If your outlet does not accommodate the three-wire plug,  
have an electrician install the correct outlet, or use an adapter to ground  
the appliance safely. Do not defeat the safety purpose of the grounded  
plug.  
z Unplug the unit during a lightning storm or when it will not be used for long  
periods of time. This will protect the monitor from damage due to power  
surges.  
z Do not overload power strips and extension cords. Overloading can result  
in fire or electric shock.  
z Never push any object into the slot on the monitor cabinet. It could short  
circuit parts causing a fire or electric shock. Never spill liquids on the  
monitor.  
z Do not attempt to service the monitor yourself; opening or removing covers  
can expose you to dangerous voltages and other hazards. Please refer all  
servicing to qualified service personnel  
z To ensure satisfactory operation, use the monitor only with UL listed  
computers which have appropriate configured receptacles marked  
between 100 - 240V AC, Min. 3.5A.  
z The wall socket shall be installed near the equipment and shall be easily  
accessible.  
z For use only with the attached power adapter (output 12V DC)which have  
UL,CSA listed license.

SPECIAL NOTES ON LCD MONITORS  
The following symptoms are normal with LCD monitor and do not indicate a  
problem.  
NOTES  
Due to the nature of the fluorescent light, the screen may flicker during  
initial use. Turn off the Power Switch and then turn it on again to make  
sure the flicker disappears.  
You may find slightly uneven brightness on the screen depending on the  
desktop pattern you use.  
The LCD screen has effective pixels of 99.99% or more. It may include  
blemishes of 0.01% or less such as a missing pixel or a pixel lit all of the  
time.  
Due to the nature of the LCD screen, an afterimage of the previous screen  
may remain after switching the image, when the same image is displayed  
for hours. In this case, the screen is recovered slowly by changing the  
image or turning off the Power Switch for hours.

NOTES  
Do not install the monitor in a location near heat sources such as radiators

mechanical vibration or shock.  
Save the original shipping box and packing materials, as they will come in  
handy if you ever have to ship your monitor.  
For maximum protection, repackage your monitor as it was originally  
packed at the factory.  
To keep the monitor looking new, periodically clean it with a soft cloth.  
Stubborn stains may be removed with a cloth lightly dampened with a mild  
detergent solution. Never use strong solvents such as thinner, benzene, or  
abrasive cleaners, since these will damage the cabinet. As a safety  
precaution, always unplug the monitor before cleaning it.

PLUG AND PLAY  
Plug & Play DDC1/2B Feature  
This monitor is equipped with VESA DDC1/2B capabilities according to the  
VESA DDC STANDARD. This allows the monitor to inform the host system of  
its identity and, depending on the level of DDC used, to communicate  
additional information about its display capabilities. The communication  
channel is divided in two levels, DDC1 and DDC2B.  
The DDC1 is a unidirectional data channel from the display to the host that  
continuously transmits EDID information. The DDC2B is a bidirectional data  
channel based on the I²C protocol. The host can request EDID information  
over the DDC2B channel.  
THIS MONITOR WILLS NOT WORK IF THERE IS NO VIDEO INPUT  
SIGNAL. IN ORDER FOR THIS MONITOR TO OPERATE PROPERLY,  
THERE MUST BE A VIDEO INPUT SIGNAL.  
This monitor meets the Green monitor standards as set by the Video  
Electronics Standards Association (VESA) and/or the United States  
Environmental Protection Agency (EPA) and The Swedish Confederation  
Employees (NUTEK). This feature is designed to save electrical energy by  
reducing power consumption when there is no video-input signal present.  
When there is no video input signal this monitor, following a time-out period,  
will automatically switch to an OFF mode. This reduces the monitor's internal  
power supply consumption. After the video input signal is restored, full power  
is restored and the display is automatically redrawn. This is similar to a  
"Screen Saver" feature except the display is completely off. The display is  
restored by pressing a key on the keyboard, or clicking the mouse.  
USING THE RIGHT POWER CORD:  
The accessory power cord for the Northern American region is the wallet plug  
with NEMA 5-15 style and is UL listed and CSA labeled. The voltage rating for  
the power cord shall be 125 volts AC.  
Supplied with units intended for connection to power outlet of personal  
computer: Please use a cord set consisting of a minimum No. 18 AWG, type  
SJT or SVT three conductors flexible cord. One end terminates with a  
grounding type attachment plug, rated 10A, 250V, CEE-22 male configuration.  
The other end terminates with a molded-on type connector body, rated 10A,  
250V, having standard CEE-22 female configuration.  
Please note that power supply cord needs to use VDE 0602, 0625, 0821  
approval power cord in European counties.
