Important Safety Instructions
Please read the following instructions carefully. This manual should be retained for future use.
1. To clean the LCD Monitor screen, first, make sure the Monitor is in the power off mode. Unplug
the Monitor from its power source before cleaning it. Do not spray liquid cleaners directly onto the
unit. Stand away from the LCD Monitor and spray cleaning solution onto a rag. Without applying
excessive pressure, clean the screen with the slightly dampened rag.
2. Do not place your LCD Monitor near a window. Exposing the Monitor to rain, water, moisture or
sunlight can severely damage it.
3. Do not place anything on top of the Monitor-to-PC signal cord. Make sure the cord is placed in an
area where it will not be stepped on.
4. Do not apply pressure to the LCD screen. Excessive pressure may cause permanent damage to the
display.
5. Do not remove the cover or attempt to service this unit by yourself. You may void the warranty.
Servicing of any nature should be performed only by an authorized technician.
6. Safe storage of the LCD Monitor is in a range of minus 20 to plus 65 degrees Celsius (68°F-149°F).
Storing your LCD Monitor outside this range could result in permanent damage.
7. If any of the following occurs, immediately unplug your Monitor and call an authorized technician.
• The power or Monitor-to-PC signal cord is frayed or damaged.
• Liquid has been spilled onto the Monitor, or it has been exposed to rain.
• The Monitor has been dropped or the case has been damaged.
8. Only with use of supplied adaptor, in case of loss or replacement contact the retailer or service cen-
ter.

CHAPTER 1
The LCD Monitor
Your New LCD Monitor!
Your LCD Monitor has been designed to be versatile, ergonomic and user-friendly. The LCD Monitor is
capable of displaying most standards, from 640 x 480 VGA to 1024 x 768 XGA. The digital controls lo-
cated on the front panel allows the user to easily adjust the Monitor’s display parameters. The LCD
Monitor’s small footprint allows you more room in your workspace for other peripherals. Lightweight and
compact, the LCD Monitor is the perfect solution for users on the go. You can use the LCD Monitor for
everything from making business presentations to playing computer games. The two stereo speakers allow
you to further expand your computer’s multimedia capabilities by connecting your computer’s Audio out
port to the LCD Monitor’s Audio in port. If you have a complete full workstation, the LCD Monitor has the
additional feature of an optional wall-mountable stand for added convenience.
The architecture of the LCD Monitor incorporates an LCD panel that produces a clear display with low ra-
diation emission, limiting health concerns. With its low power consumption, the LCD Monitor helps you
reduce your power bill.
Unpacking
Before you unpack your LCD Monitor, prepare a suitable workspace for your LCD Monitor and computer.
You need a stable, level and clean surface near a wall outlet. Even though the LCD Monitor uses very little
power, you should put it in a location which allows sufficient airflow to ensure that the LCD Monitor and
your computer does not become too hot. Set up your LCD Monitor so that the panel doesn’t face a window
where sunlight often comes in. The glare caused by sunlight reflecting off the LCD Monitor’s screen will
makes it difficult to see.
Using a computer for an extended period of time with a poor workstation set-up and incorrect
working habits can cause health problems. The science of ergonomics studies the relationship
between health and a suitable working environment. There is a section on ergonomics at the
end of this chapter. For more information on ergonomics, contact your nearest computer book-
store, or local library. The Internet also has information on this and other subjects.
After you unpack your LCD Monitor; make sure the following items are included in the box and in good
condition:
• LCD Monitor
• Monitor-to-PC signal cable
• 1.5M Stereo Jack Audio Cable
• AC Adapter
• Power cord
• This user’s manual
If you find that any of these items are missing or appear damaged, contact your dealer immediately. Do not
throw away the packing material or shipping carton in case you need to ship or store the LCD Monitor in the
future.

Troubleshooting
Troubleshooting Procedures
This LCD Monitor was pre-adjusted in the factory with standard VGA timing. Due to output timing differ-
ences among various VGA cards, you may initially experience an unstable or unclear display when a new
display mode or new VGA card is selected.
This LCD Monitor Supports Multiple VGA Modes. Refer to Addendum for a listing of the fac-
tory preset modes supported by this LCD Monitor.
PROBLEM: Display is Unclear and Unstable
To stabilize and clarify your display, follow this procedure in this order:
It’s best to adjust the display on a screen displaying of vertical lines. In Windows, load a
wallpaper bitmap that has vertical lines in it. (or you can select the window shut down screen)
After you have the wallpaper loaded, open the OSD and select the “Clock” function. Press the
top (or bottom) Adjustment Control button and continue pressing the button until you see ver-
tical dark and light lines across the screen.
When you can see distinct light and dark vertical bands, stop pressing the Adjustment Control
button. Now press the opposite (top or bottom) Adjustment Control button. The vertical dark
and light bands will decrease in number. Keep pressing the button until the distinct bands
disappear and you have a clear display.
Next, press the Function Control button to choose the “Phase” function. The Phase will ad-
just the horizontal display. Press the top (or bottom) Adjustment Control button and you will
see horizontal dark and light lines appear. The number of lines increases as you press the but-
ton. Now press the bottom (or top) Adjustment Control button until the lines disappear and
you have a clear display.
PROBLEM: There is no LCD Display
If there is no display on the LCD, please perform the following steps:
Make sure that the power indicator on the LCD Monitor is lit, all connections are secure, and
the system is running on the correct timing. Refer to the Addendum for information on tim-
ing.
Turn off the LCD Monitor and then turn it back on again. Press the upper Function Control
button (refer to Chapter 2) once and then press either the upper or lower Adjustment Control
button several times. If there is still no display, press the other Adjustment Control button
several times.
If step 2 doesn’t work, connect your PC system to another external CRT. If your PC System
functions properly with a CRT Monitor but it does not function with the LCD Monitor, and
the LCD Monitor’s power LED is blinking, the output timing of the PC’s VGA card may be
out of the LCD’s synchronous range. Please change to an alternate mode listed in Addendum
or replace the VGA card and repeat steps 1 and 2.
13
User’s Manual
If the PC doesn’t function with the CRT monitor neither, check BIOS to see if there is a dual
scan setting under the display mode item. Set the BIOS display mode to Dual Scan or CRT
and try again. If there is still no display, then there may be a problem with your system.
Contact technical support.
If the power LED is not lit, check to see if the AC power connector is securely connected.
Verify that the AC adapter LED is lit. If the AC adapter LED is not lit, please contact your
dealer for assistance.
