LCD PANEL
When the monitor is cold and brought into a room or the room temperature goes up quickly,
dew condensation may occur inside and outside the monitor. In that case, do not turn the
monitor on and wait until dew condensation disappears, otherwise it may cause some
damages to it.
In order to suppress the luminosity change by long-term use and to maintain the stable
luminosity, please use the monitor with the lower brightness.
The screen may have defective pixels. These pixels may appear as slightly light or dark area
on the screen. This is due to the characteristics of the panel itself, and not the product.
The backlight of the LCD panel has a fixed life span. When the screen becomes dark or
begins to flicker, please contact your dealer.
Do not press on the panel or edge of the frame strongly, as this may result in damage to the
screen. There will be prints left on the screen if the pressed image is dark or black. If
pressure is repeatedly applied to the screen, it may deteriorate or damage your LCD panel.
Leave the screen white to decrease the prints.
Do not scratch or press on the panel with any sharp objects, such as a pencil or pen as this
may result in damage to the panel. Do not attempt to brush with tissues as this may scratch
the LCD panel.
When the screen image is changed after displaying the same image for extended periods of

4. ADJUSTMENT
This touchmonitor will not likely require adjustment. Variations in video output and
application may require adjustments to the touchmonitor to optimize the quality of the
display.
For best performance, the touchmonitor should be operating in native resolution 1600 x
1200. Use the Display control panel in Windows to choose 1600 x 1200 resolution.
Operating in other resolutions will degrade video performance.
All control adjustments are automatically memorized.

4.3 Screen Adjustment
Screen adjustments for the LCD monitor should be used in suppressing screen flickering
and also for adjusting the screen to its proper position. There is only one correct position for
each display mode. It is also recommended to use the OSD Menu function when first
installing the display or whenever changing the system.
Note: Allow the LCD monitor to stabilize for at least 20 minutes before making image
adjustments.Making Adjustting must be VGA signal.
Adjustment Procedure
1. Adjust by <Auto Adjust> menu in the OSD Menu.
To automatically adjust the clock, phase, screen position and resolution.
Note:
The Auto sizing function is intended for use on the computer running Windows. It may not
work properly when the computer is running on MS-DOS (Not windows) or the background
color for the "wall paper" or "desktop" pattern is set to black.
If the appropriate screen cannot be made by using the Auto adjustment button, adjust the
screen through the following procedures.

2. Adjust by using <VGA> menu in the OSD Menu.
(1) Vertical bars appear on the screen
→ Use the <Clock> adjustment.
Select the <Clock> and eliminate the vertical bars by using the UP and Down of the Control
buttons.
Do not continuously press the Control buttons, as the adjustment value will change quickly
and make it difficult to locate the most suitable adjustment point. If the horizontal flickering,
blur or bars appear, proceed to <Phase> adjustment as follows.
(2) Horizontal bars appear on the screen.
→ Use the <Phase> adjustment.
Select the <Phase> and eliminate the horizontal flickering, blurring or bars by using the
Right and Left buttons.
Note: Horizontal bars may not completely disappear from the screen depending on the
computer.
(3) The screen position is incorrect.
→ Use the <Position> adjustment.
The <Position> adjustment moves the image to the correct position. Select <Position> and
adjust the position by using the Up and Down buttons.
If vertical bars of distortion appear after finishing the <Position> adjustment, return to

5. TROUBLESHOOTING
If a problem persists even after applying the suggested remedies, contact a dealer.
Problems Points to check with Possible Solutions
1. No picture
Indicator status: Off
Check that the power cord is correctly connected. If the
problem persists, turn off the monitor power for a few
minutes, then turn it back on and try again.
- when the signal is not inputted correctly, even if the monitor
functions properly.
- When the image is displayed correctly after a short time,
there is no problem with the monitor. (Some PCs do not
output the signal soon after powering on.)
Check that the signal cable is properly connected to the PC or
graphics board.
Indicator status: Green Check the "Brightness" setting.
2. Display position is
incorrect.
Adjust the image position using the <Position>. If the
problem persists, use the graphics board's utility software to
change the display position if available.
3.Vertical bars of
distortion appear.
Decrease the horizontal bars using the <Clock>.
4 Horizontal bars of
distortion appear.
Decrease the horizontal bars using the <Phase>.
5 The screen is too
bright or too dark.
Adjust the <Brightness> (The backlight of the monitor has a
fixed life span. When the screen becomes dark or begins to
flicker, please contact your dealer.)
6. Afterimages appear.
- Do you use the screen saver or timer when displaying the
same image for extended periods of time?
- Afterimages are particular to monitors. Avoid displaying the
same image for extended periods of time.
7. The screen has
defective pixels
(e.g. slightly light
or dark).
This is due to the characteristics of the panel itself, and not
the product.
8. Touch doesn’t work. Make sure the touch cable is securely attached at both ends.

6. CLEANING
Periodic cleaning is recommended to keep the monitor looking new and to prolong its
operation lifetime.
Note: Never use thinner, benzene, alcohol (ethanol, methanol, or isopropyl alcohol),
abrasive cleaners, or other strong solvents, as these may cause damage to the cabinet or
LCD panel.
Cabinet
