Section 1: Introduction
Product Description
Your new touch monitor combines the latest developments in touch technology and display design with reliability for use in high-traffic environments.
This touch monitor incorporates a 24-bit color, active matrix thin-film-transistor LCD panel to provide high-quality display performance. The 03 Series
includes full sizes from 19 to 27 inches and supports resolutions from 1280 x 1024 to full HD 1920 x 1080. Its LED backlight significantly reduces power
consumption and eliminates the need for mercury (compared to CCFL-backlit panels). Other features that enhance this LCD monitor’s performance are
Plug & Play compatibility, remote on-screen display (OSD) controls and flexible mounting options.
This monitor is DICOM 14 compliant and follows AAPM-TG18 secondary medical display criteria (less than 20% variance in contrast). The monitor can
be used in a variety of non-diagnostic healthcare applications and environments including: self check-in/registration or point-of-information in hospitals
and clinics, EHR review, various kinds of modality where image reconstruction, reprocessing, or post-processing is required, clinical image review, ER,
and surgical applications. The monitor is powered by an externally recognized AC/DC adaptor.
Precautions
Follow all warnings, precautions and maintenance as recommended in this user manual to maximize the life of your unit and prevent risks to user safety.
See the Safety & Maintenance Section for more information.
This manual contains information that is important for the proper setup and maintenance of the unit. Before setting up and powering on your new touch
monitor, read through this manual, especially the Installation, Mounting, and Operation Sections.

Installing the Touch Technology Software Drivers
No additional drivers are required for your projected-capacitive touch monitor with Windows 7 or 10 operating systems, as it will use the Windows HID
drivers.
If the monitor is used with the Windows XP operating system or you want to use RS232 touch (touch via COM port), follow the steps below to install the
Windows XP touch driver.
To download the latest touch drivers:
1. Visitwww.elotouch.com/Support/Downloads/Driver/DriverDownload/Default.aspx
2. Select the operating system from the Operating System drop-down menu.
3. Select the technology from the Technologies drop-downmenu.
4. Download the driver version required for your touch monitor. (later than 7.0 for RS232 touch)
For RS232 touch, please check with and Elo sales rep or Elo support team to purchase the Elo Y-cable (Elo P/N: E810917) separately.

Magnetic Stripe Reader (MSR) Installation (Optional)
Your monitor comes with four pheripheral ports, located at the top, bottom, left and right sides of the monitor. To mount an MSR, remove one of the
pheripheral port covers with your finger tips and install the MSR as shown below. Please refer to the MSR Quick Install Guide (QIG) for set-up details.

Wall Mount
Mount the wall bracket to the wall using six fasteners appropriate for the type of wall material and following all applicable building code standards.
Ensure the unit is mounted to a solid structure and surface, such as a support beam or wall.
Attach the other bracket to the monitor using the four M4 screws included in the kit.
Hang the monitor on the wall bracket and secure using two M3 screws included with the kit on the left and right side of the bracket.

Section 4: Operation
Power
To turn the touch monitor on or off, press the touch monitor’s power button once.
The Power Status LED on the bottom of the touch monitor functions as follows:
Touch Monitor Status
LED Status
OFF
OFF
SLEEP
PULSING (Orange)
ON
ON ( Green)
The system consumes low power when in SLEEP or OFF modes. For detailed power-consumption specifications, refer to the technical
specifications on the Elo website http://www.elotouch.com
Touching the screen will bring the attached host PC out of SLEEP mode (similar to moving the mouse or pressing a keyboard key).
To improve reliability and reduce wasteful power consumption, disconnect the AC power cable from the monitor when long periods of disuse are planned.
Touch
No calibration is required for projected capacitive touch technology. Your touch monitor can support up to 10 touches (2 touches for RS232 touch) at
once.
Note: When using a privacy filter with your monitor, it is important to update the touch configuration file of you monitor to support touch.
For 2 touches with 3mm cover glass support, simply go to the OSD menu and enable the touch-through function (Recommendpowercycle). Do not forget to
disable the touch-through function when using the monitor without a privacy screen.
Touch Technology & Capacity
TouchPro® PCAP - up to 10 touches with palm rejection and touch through capability.
Direct Touch
Support 10 touches with direct finger, capacitive stylus, privacy filter, and/or latex gloves (2 layers).
Touch Through
Support up to 3mm glass with up to 2 touches. Limited power palm support.

Projected Capacitive Touch Technology
When connected to Windows 7 or 10 computers, the touch monitor can detect 10 simultaneous touches. When connected to Windows XP computers, the
touch monitor detects only single touches.
No additional drivers are required for this technology to work with Windows 7 or 10, as it uses Windows HID drivers.
Refer to Section 2, “Installing the Touch Technology Software Drivers,” for instructions on downloading touch drivers for Windows XP or RS232 touch.
No calibration is required for this technology.

Gesture Support
TouchPro PCAP technology enables several gestures that support single and multiple touches. Refer to the Microsoft website at
http://msdn.microsoft.com/en-us/library/dd940543 on the various gestures that are supported in Windows 7, 10 and later OS versions.
Video
A display’s native resolution is its width and height measured in pixels. Generally, for best performance, an image displayed on this monitor will look best
when your computer’s output resolution matches this monitor’s native resolution, which is 1280 x 1024 for the 1903L and 1920 x 1080 for the 2203L, 2403L
and 2703L monitors.
For computer output at non-native resolutions, the monitor will scale the video to its panel’s native resolution. This involves stretching or compressing the
input image as needed in the X and Y dimensions to fit the display’s native resolution. An unavoidable byproduct of the scaling algorithms is a loss of
fidelity when the computer’s output video image is scaled by the monitor to fit the display. This loss of fidelity is most apparent when viewing feature-rich
images at close distances (e.g., images containing small-font text).
Your touch monitor will likely not require video adjustments. However, for analog VGA video, variations in video graphic card outputs may require user
adjustments through the OSD to optimize the quality of the touch monitor’s displayed image. These adjustments are stored by the touch monitor. Also, to
reduce the need for adjustments for different video mode timings, the monitor correctly scales and displays some of the video industry’s most common
video timing modes. Refer to the technical specifications for this monitor at http://www.elotouch.com for a list of these Preset Video Modes.
On-Screen Display (OSD)
Five OSD buttons are located on the rear of the monitor. These can be used
to adjust various parameters. The buttons and their functionalities are:
