FCC Class B Radio Frequency Interference Statement
WARNING: (FOR FCC CERTIFIED MODELS)
NOTE: This equipment has been tested and found to comply with the limits for
a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates, uses and can radiate
radio frequency energy, and if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
4. Consult the dealer or an experienced radio/TV technician for help.
NOTICE:
1.
2.
3.
The changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate the
equipment.
Shielded interface cables and AC power cord, if any, must be used in
order to comply with the emission limits.
The manufacturer is not responsible for any radio or TV interference
caused by unauthorized modification to this equipment. It is the
responsibilities of the user to correct such interference.
WARNING:
To prevent fire or shock hazard, do not expose the monitor to rain or moisture.
Dangerously high voltages are present inside the monitor. Do not open the
cabinet. Refer servicing to qualified personnel only.

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 use an adapter to 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.

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.
When the screen becomes black or flashing, or cannot illuminate any more,
contact your dealer or service center to replace parts. Don’t repair the
screen by yourself!

Do not install the monitor in a location near heat sources such as
radiators or air ducts, or in a place subject to direct sunlight, or excessive
dust or mechanical vibration or shock.
Save the original shipping carton and packing materials, as they will come

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 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 European counties.
