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 has UL, CSA listed license

Specific notes in LCD monitor

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.

HOW TO OPTIMIZE THE DOS-MODE
PLUG AND PLAY
Plug & Play DDC1/2B Feature

This monitor is equipped with VESA DDC1/2B 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 communication channel is defined 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 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 Europe
