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. The changes or modifications not expressly approved by the party

responsible for compliance could void the user's authority to operate the
equipment.

2. Shielded interface cables and AC power cord, if any, must be used in

order to comply with the emission limits.

3. 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.

As an ENERGY STARPartner our company has determined that this
product meets the ENERGY STARguidelines for energy efficiency.

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.

2

PRECAUTIONS

 Do not use the monitor near water, e.g. near a bathtub, washbowl,

kitchen sink, laundry tub, swimming pool or in a wet basement.

 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.

 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.

 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.

 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.

 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.

 Do not overload power strips and extension cords. Overloading can result

in fire or electric shock.

 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.

 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.

 To ensure satisfactory operation, use the monitor only with UL listed

computers which have appropriate configured receptacles marked
between 100 - 240V AC, Min. 5A.

 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 has
been displayed for a long time. The monitor will slowly recover from this.

 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 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.

CLOCK and FOCUS or perform hot- key

CLOCK (pixel frequency) controls the number of pixels scanned by one
horizontal sweep. If the frequency is not correct, the screen shows vertical
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 shut­down mode pattern.
