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, uses 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. 5A.
z The wall socket shall be installed near the equipment and shall be easily accessible.
Special Notes on LCD Monitors
The following symptoms are normal with LCD monitor and do not indicate a problem.
Notes
z 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.
z You may find slightly uneven brightness on the screen depending on the desktop pattern you use.
z 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.
z 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.

How to Optimize The DOS-Mode
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 bi-directional data channel 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 signals 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. Pressing a key on the keyboard, or clicking the mouse
restores the display.
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, and 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.
Enter into the factory mode:
Turn off the power, press the “e-color” and turn the power on. The factory OSD will be at the left top of the panel.
