Precautions  
EN7400e  
• Do not use the monitor near water, e.g. near a  
pin. As a safety feature, this plug will only fit  
bathtub, washbowl, kitchen sink, laundry tub,  
swimming pool or in a wet basement.  
into a grounded power outlet. 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.  
• 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.  
• 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.  
• 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.  
• 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 yourself;  
opening or removing covers can expose you to  
dangerous voltage 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 appropriately configured receptacles  
marked between 100 - 240 V AC, Min. 5A.  
• The monitor should be operated only with 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 wall socket should be installed near the  
equipment and should be easily accessible.  
• Disconnect the power cord to stop the power  
supply to the monitor.  
• Do not overload power strips and extension  
cords. Overloading can result in fire or electric  
shock.  
• The monitor is equipped with a three-pronged  
grounded plug, a plug with a third (grounding)

Special Notes on LCD Monitors  
General Notes  
The following symptoms are normal with an LCD  
monitor and do not indicate a problem:  
• Do not install the monitor near heat sources  
such as radiators or air ducts.  
• 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.  
• Do not place monitor in direct sunlight or in  
areas with excessive dust, mechanical vibration  
or shock.  
• Save the original shipping carton and packing  
materials in case you need to ship your monitor.  
Be sure to repackage your monitor as it was  
originally packed at the factory.  
• 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.  
• Periodically clean your monitor 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 thinners,  
benzene, or abrasive cleaners, since these  
will damage the cabinet. Always unplug the  
monitor before cleaning it.  
• Due to the nature of the LCD screen, an after-  
image of the previous screen may remain after  
switching from an image that has been  
displayed for hours. This after-image could  
require several hours to disappear.  
Using the Right Power Cord  
The supplied power cord is a NEMA 5-15 style  
plug. It is UL-listed and CSA labeled for  
125 volts AC.  
• The life of the fluorescent light used in the LCD  
monitor is approximately 20,000 hours. Contact  
your dealer or EPI service center for  
replacement when the screen is dark, flickering  
or not lighting up. Never attempt to replace it by  
yourself.  
If the monitor will be connected to your computer’s  
power outlet, use a minimum No. 18 AWG, type  
SJT or SVT three conductors cord with one end  
terminating with a male grounded plug, rated 10A,  
250V, CEE-22. The other end must terminate with  
a molded-on type connector body, rated 10A,  
250V, having standard CEE-22 female  
configuration.

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.

Dead Pixel Criteria  
• In order to provide the highest performing products, EPI has set the following  
limits as to the maximum allowable number of bad pixels: 5 Bright Sub-pixels  
or 5 Dark Sub-pixels or combination of 8 Dark & Bright. The panel used on  
this product has a total of 3,932,160 sub-pixels. So even the maximum  
allowed of 6 bad sub-pixels would only amount to a very small 0.0002% of the  
total sub-pixels

Problem  
Possible Solution  
• Adjust the CLOCK1 and FOCUS2 settings or press the AUTO button to  
automatically re-configure the monitor’s settings.  
Screen image is not  
centered or sized  
properly  
Picture has color  
defects (white does  
not look white)  
• Adjust the settings for Red, Green and/or Blue colors or select a different  
color temperature: 65 (6500 K) or 78 (7800 K).  
Poor brightness or  
contrast  
• The life time of the back-light is limited. After 20,000 hours, the luminance of  
the light has been reduced to half of its original value. Please send the  
monitor to an authorized service agent for service.  
Horizontal or vertical  
disturbances on the  
screen  
• Adjust the CLOCK and FOCUS settings or press the AUTO button to  
automatically re-configure the monitor’s settings.  
• Use Win 95/98 shut-down mode.  
1CLOCK (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’s width is incorrect.  
2FOCUS adjusts the phase of the pixel clock signal. With a wrong phase adjustment the picture has horizontal  
disturbances with very light screen images.  
Note: For FOCUS and CLOCK adjustment use “dot-pattern” or Win 95/98 shut-down mode pattern.
