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.

EN7220  
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 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.  
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 lightning 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.

GENERAL NOTES  
SPECIAL NOTES ON LCD MONITORS  
The following symptoms are normal with LCD monitor and do not indicate a  
problem.  
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 panel used in this monitor is a very high technology product with  
3,932,160 thin film transistors giving you fine picture details. Occasionally,  
a few non-active pixels may appear on the screen as a fixed point of red,  
green, blue, white or black. Please note that this does not indicate a  
defective panel.  
Due to the nature of the LCD screen, an after-image 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.  
LCD monitors have a fixed size & number of pixels. Due to this, an  
interpolation is necessary to operate the monitor in a relution below it’s  
native resolution which may slightly degrage the display quality.  
Therefore, it is highly recommended to operate the monitor at it’s native  
resolution of 1280 x 1024 @ 60Hz.  
OTHER NOTES  
The screen surface is very soft. Do not rub, touch or tap the screen  
surface with sharp object such as pen or pencil. This contact may scratch  
or damage the screen. These damages are not covered under the  
warranty.  
Turn your computer OFF before installing your new monitor. Refer to your  
computer manual for the proper shut down procedure.  
Save the original shipping carton and packing materials, as they will come  
in handy if you ever have to ship your monitor.  
For maximum protection, repackage your monitor as it was originally  
packed at the factory.  
To keep the monitor looking new, periodically clean the case & surface of  
the TFT-LCD panel with a soft non-fiberous cloth lightly dampened with a  
glass cleaner. Do not use any paper products to clean the screen. Never  
spay the glass cleaner directly on the monitor. Never use strong solvents  
such as thinner, benzene, or abrasive cleaners, since these will damage  
the case & panel. As a safety precaution, always unplug the monitor  
before cleaning it.

GENERAL NOTES (cont)  
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 not video input  
signal. In order for this monitor to operate properly, there must be a video  
input signal.

TECHNICAL SUPPORT (FAQ) (cont)  
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 shut-down  
mode pattern.  
ERROR MESSAGE & POSSIBLE SOLUTION  
CABLE NOT CONNECTED :  
1. Check that the signal-cable is properly connected , If the connector is  
loose, tighten the connector’s screws.  
2. Check the signal -cable connection pins for damage.  
INPUT NOT SUPPORT :  
Your computer has been set to unsuitable display mode. Set the computer  
to a display mode given in the Preset Display Modes table.
