3.3 Additional On Screen Display (OSD) Information
The OSD disappears (times-out) several seconds after you stop pressing the buttons
while performing an adjustment. This function can be adjusted up to 60 seconds allow-
ing the user more time. This adjustment is made in the “Settings” submenu.
Any changes made are automatically saved in the Touch Monitor memory when the
OSD disappears. Turning off the power should be avoided while using the OSD, as this
may not allow changes to be saved.
Adjustments for clock, phase and positions are saved for each signal timing or screen
resolution. Except for these adjustments, all other adjustments have only one setting
that applies to all signal timing.
The submenu color will change from white to pink when the function is selected.
You can skip the OSD menu and display commonly used adjustment scales directly by
using the following button operations (refer to previous diagram for button locations):
Brightness Press the Brightness Button (3) when the Menu is not displayed.
Contrast Press the Contrast Button (2) when the Menu is not displayed.
Auto Setting Press the Auto Button (5) when the Menu is not displayed.
The Auto Adjust process may take as much as 10 consecutive seconds. The display image
will make noticeable changes as the Auto Adjust function completes.
3.4 Self Test Check
This product provides a self-test ability, through which you can check whether the LCD
monitor functions are working properly.
If your LCD monitor is properly connected, but there is no image showing and the power
indicator light on the Touch Monitor displays orange, please follow the steps below:
1. Turn off both the computer and LCD monitor.
2. Unplug the video signal connector from the back of the computer.
3. Turn the LCD monitor on.
4. The monitor should display “No Signal Input” on the screen and the power LED indicator
should be orange. If no display is observed, there may be a problem with the Touch
Monitor.
5. Turn off the LCD monitor and reconnect the signal cable, then turn the computer and LCD
monitor on. As the computer boots, there should be a video display and the power LED
should now be green. If the LED of the monitor is an orange color after completing the
steps above, please check your VGA card and computer system.

Touch Screen
5
Section
Touch screens are a common means to interface operator inputs to a system. The universal
standard of Windows GUI (Graphical User Interface) has significantly increased the use of
touch screens.
There are four main touch technologies. The technologies are resistive, surface acoustic
wave (SAW), capacitive, and infrared (IR). Each touch technology has advantages and
disadvantages based on different user applications.
All Vartech Systems displays configured with a touch screen are supplied with a CDROM
which includes user manuals, application software, and drivers for various operating systems.
Insert the supplied CDROM into a CDROM drive and follow the installation instructions that
will appear on the screen.
Limited technical support is available by contacting Vartech Systems customer support at
800-223-8050.

Notes

Section
SPECIAL NOTES ON LCD TOUCH MONITORS
The following are normal with LCD Touch Monitors and do not indicate a problem.
• When the LCD Touch Monitor is first powered on, the picture may not fit in the display area. This is
because of the type of computer graphics system that is used. In such case, adjust the picture posi-
tion to a desired image (See Operating the Monitor).
• The screen may flicker during initial use. Turn off the power and then turn it on again the flickering
should disappear.
• Users may notice some uneven brightness on the screen depending on the desktop resolution they
use. It is normal for LCD Touch Monitors to show uneven brightness.
• Due to the nature of the LCD displays, images displayed on the screen for long periods of time may
still appear after the screen content has been changed. This phenomenon can be corrected, over
time, by switching display content or leaving the monitor off for a number of hours.
• If the screen becomes dark, flickers, or does not light-up, contact your dealer or the nearest service
center for a backlight replacement. Do not attempt to replace it yourself.
