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 cart, stand, or table. If the monitor  
falls, it can injure a person and cause serious damage to the appliance.  
Use only a cart 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 ground the appliance safely.  
Do not defeat the safety purpose of the grounded plug.  
z Unplug the unit during a lightening storm or when it will not be used for  
long period 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 by 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. 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 12Vdc) 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.

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

PLUG AND PLAY  
Plug & Play DDC2B Feature  
This monitor is equipped with VESA DDC2B capabilities according to the  
VESA DDC STANDARD. It allows the monitor to inform the host system of its  
identity and, depending on the level of DDC used, communicate additional  
information about its display capabilities.  
The DDC2B is a bidirectional data hannel based on the I2C protocol. The  
host can request EDID information over the DDC2B channel.  
THIS MONITOR WILL APPEAR TO BE NON-FUNCTIONAL 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 conserve 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. The appearance 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.

stripes and the picture has not correct width.  
FOCUS adjusts the phase of the pixel clock signal. With a wrong phase  
adjustment the picture has horizontal disturbances in light picture.  
For FOCUS and CLOCK adjustment use “dot-pattern” or win 95/98 shut-down  
mode pattern.
