1INTRODUCTION
Congratulations on your purchase of an Elo TouchSystems Entuitive touchmonitor. Your
new high-resolution touchmonitor combines the reliable performance of Elo’s touch
technology with the latest advances in CRT display design. This combination of features
creates a natural flow of information between a user and the touchmonitor.
1.Precautions

TOUCH TECHNOLOGY
1.Touchscreens: An Overview
Typically, users communicate with computers by using a mouse, a keyboard, or a
combination of the two. Users who are not keyboard-literate or mouse-savvy can become
frustrated with how long human-to-computer interactions take.
Computer literacy is learned. This is complicated by the fact that using a keyboard or a
mouse is neither intuitive nor natural for most people.
Touchscreens cut out the learning curve by eliminating keyboard/mouse intermediaries and
allowing a natural flow of information to develop between a user and a computer.
When a user wants to access information or perform a function on a computer with a
touchscreen installed, a touch quickly and accurately does the job that once required
complicated keyboard interactions or precise mouse movements.
A frustrating experience with a computer during a transaction can create dissatisfaction for
your customer. Touchscreens help eliminate unpleasant transactions by creating a natural
flow of information that enhances your product or service. Touchscreens speed up
user/computer interactions. People get what they want faster and are more satisfied with
the process.

2.iTouch Touchscreens
Elo built on its IntelliTouch surface wave technology to create its iTouch "touch-on-tube"
solution. Elo eliminated the clear glass layer between the viewer and the display. iTouch
touchmonitors have been adopted by some of the largest manufacturers in the world in their
next generation games.
Elo CRT gaming monitors offer consistent features across all sizes:
•Touch directly on tube—no touchscreen overlay and no parallax.
•Preserves 100 percent of CRT brightness, clarity, antireflection and color properties.
•More durable and safer than even bonded touchscreen overlays.
•Same fast, accurate, stable performance as Elo’s IntelliTouch surface wave
touchscreen overlays.
•"Drift free" and not affected by surrounding metal or poor earths/grounding.
•Dual touches are not averaged, allowing extremely fast two-handed play.
•Z-axis for pressure can add a new dimension to games.
•No need for periodic recalibration.

5.Connect the Power Cable
•Your monitor does not include a power cable. You may either purchase a country
specific power cable from Elo (www.elogaming.com), or construct your own custom
power cable (see page 4 for details). Connect the power cable to the AC connector on
your touchmonitor. To protect your equipment against risk of damage from electrical
surges in the power line, plug the touchmonitor’s power cord into a switched surge
protector, and then connect the surge protector to a grounded (three-pronged) AC
electrical outlet.
•Your touchmonitor has no power switch. Power on your monitor using the power switch
of the surge protector, and check that the power LED is on. If not, refer to page 32,
Troubleshooting.
•After a brief pause the picture should appear. If necessary, adjust the front panel controls
according to your personal preference (see page 13).
•Insert the Elo TouchTools CD-ROM in your computer’s CD-ROM drive to install the
appropriate touchscreen driver software. Follow the directions starting on the next page
to install the driver software.
6.Installing the Driver Software
Elo TouchSystems provides driver software that allows your touchmonitor to work
with your computer. Drivers are located on the enclosed CD-ROM for the following
operating systems:
•Windows XP
•Windows 2000
•Windows Me
•Windows 98
•Windows 95
•Windows NT 4.0
Additional drivers and driver information for other operating systems are available on the
Elo TouchSystems web site at www.elogaming.com.

of your touchmonitor is sent to your video display adapter when
Windows starts. If Windows detects your touchmonitor, follow the instructions on the
screen to install a generic plug-and-play monitor.
Refer to the appropriate following section for driver installation instructions.
7.Installing the Touch Driver for Windows XP, Windows 20001, Me,
95/98 and NT 4.0
NOTE: For Windows 2000 and NT 4.0 you must have administrator access rights to
install the driver.
1.Insert the Elo CD-ROM in your computer’s CD-ROM drive.
If the AutoStart feature for your CD-ROM drive is active, the system
automatically detects the CD and starts the setup program.
2.Follow the directions on the screen to complete the driver setup for your version of
Windows.
If the AutoStart feature is not active:
1.Click Start > Run.
2.Click the Browse button to locate the EloCd.exe program on the CD-ROM.
3.Click Open, then OK to run EloCd.exe.
4.Follow the directions on the screen to complete the driver setup for your version of
Windows.
8.Installing the Touch Driver for MS-DOS and Windows 3.1
You must have a DOS mouse driver (MOUSE.COM) installed for your mouse if you
wish to continue using your mouse along with your touchmonitor in DOS.
To install Windows 3.x and MS-DOS from Windows 95/98, follow the directions
below:
1.Insert the Elo CD-ROM in your computer’s CD-ROM drive.
2.From DOS, type d:\EloDos_W31 to change to the correct directory on the CD-ROM
(your CD-ROM drive may be mapped to a different drive letter).
3.Type install and press Enter to start the installation.
4.Align the touchscreen.
You must have already completed Steps 1 and 2 before proceeding. Refer to page 9 of
the Elo DOS and Windows Driver Guide as necessary for additional installation
information.
To run the INSTALL program:
1.Type INSTALL at the DOS prompt in the directory containing the driver install files.
2.INSTALL asks you to select the software to install. Then choose d:\EloDos_W31
from the displayed list.
3.INSTALL also asks you for the paths to use during installation, or you may use its
defaults. INSTALL creates directories as necessary, and warns you if they exist.
If you are updating your software, you may wish to specify the paths containing the
earlier versions, and overwrite the obsolete files. All executable programs are upward
compatible. For a list of differences from each previous version of the drivers, be
sure to select "Differences from Previous Versions" during the installation process.
INSTALL updates your AUTOEXEC.BAT file with the drivers you select.
INSTALL makes a copy of your original AUTOEXEC.BAT file, called

- 13 -
AUTOEXEC.OLD. If you already have Elo driver commands in your
AUTOEXEC.BAT file, they will be commented out.
When INSTALL is finished, it leaves a file called GO.BAT in the subdirectory you
specified. GO loads the touchscreen driver, runs the calibration program
ELOCALIB, and gives you some final instructions.
If you are using Windows 3.1, you will also calibrate the touchscreen within Windows
3.1 with the Touchscreen Control Panel.
OPERATION
1.About Touchmonitor Adjustments
By design, your Elo Entuitive touchmonitor should not require any adjustments.
The factory settings will give you optimum video results with most standard PC video
display adapters.
However, after connecting your touchmonitor you can further optimize the settings to
meet your requirements by following the directions in this chapter.
All adjustments you make to the controls are automatically memorized, so you do not
need to reset your choices every time you unplug your touchmonitor or power it off
and on. If there is a power failure your touchmonitor settings will not default to the
factory specifications.
IMPORTANT: Do not insert conductive metal objects into the monitor's circuitry. The
monitor uses high voltages and the metal edges can be sharp.
Disassembly or realignment of the monitor circuitry voids the warranty.
2.Touchmonitor Controls
You can adjust the screen display by using the plastic knob labeled OSD located on
the right-hand side of the touch controller bracket.
2.1 Using the On Screen Display (OSD)
2.1.1 Push the OSD knob to access the OSD.
2.1.2 Turn the OSD knob to choose the item you want to adjust. The selected item
is highlighted. See figure 1 for OSD menu options.
2.1.3 Push the OSD knob to adjust the highlighted item.
The display unit automatically saves the new settings in about 45 seconds
after your last adjustments. The menu will automatically disappear or you can
push the OSD knob to make the menu disappear.
