About This Manual
Congratulations on the purchase of your MicroTouch™ ToughTouch II product and
welcome to the world of 3M Touch Systems — a world where using a computer is as
simple as touching the screen.
MicroTouch™ ToughTouch II – along with its best-in-class MicroTouch™ EX II touch
electronics – sets the standard in rugged capacitive touch screen offerings. Designed to
withstand heavy abuse in unattended, vandal-prone applications, MicroTouch™
ToughTouch II capacitive touch screens are an ideal solution for extreme environments
that require a toughened, shatter-resistant, liquid-resistant touch solution. Whether you’re
designing ticketing kiosks or gaming machines, providing ATM solutions or require a
toughened product for challenging industrial environments, ToughTouch II touch screens
can meet or exceed your design requirements.
ToughTouch II is constructed by optically laminating 4 mm glass to the back of a
MicroTouch™ ClearTek™ II touch screen – the standard for capacitive touch screens.
By combining ClearTek II’s industry-leading features for reliability and robustness with
laminated impact-resistant characteristics, ToughTouch II offers excellent touch
performance when and where ever you need it.
• Laminated construction provides high impact resistance for vandal-prone locations.
• Excellent light transmission supports dynamic interactive applications.
• NEMA 4/IP66 seal-ability protects from liquids and other contaminants affecting
touch screen operation or damaging the LCD display.
• UL-60950 Third Edition.
• Available “viewer privacy” feature with 3M Vikuiti Light Control Film for ATMs
and many public applications.
Each MicroTouch™ ToughTouch II screen requires an EX II touch screen controller.
These controllers come in different form factors and may be cased or uncased; refer to the
appropriate EX II Controllers Reference Guide and the MT 7 Software User Guide for
more information on your touch system. All technical documentation is available from
the 3M Touch Systems website at http://www.3Mtouch.com/

Important Notes for Video Displays
• Plug power cord into appropriate power source.
• Plug power cord into a grounded receptacle.
• When unplugging power supply cord, pull on the plug not the cord.
• Do not connect or disconnect this product during an electrical storm.
• Install the display in a well-ventilated area. Always maintain adequate ventilation to
protect the display from overheating and to ensure reliable and continued operation.
• Do not expose the display to direct sunlight or heat. Passive heat may cause damage
to the case and other parts.
• Do not install the display in areas where extreme vibrations may be generated. For
example, nearby manufacturing equipment may produce strong vibrations. The
vibrations may cause the display to exhibit picture discoloration or poor video
quality.
• Ensure that metal enclosures or bezels do not directly contact the touch screen.
• To avoid ergonomic concerns:
Do not install the LCD in a manner or location with awkward accessibility.
Extended use may result in muscle, tendon, or fixed posture strains. It is
recommended you take periodic breaks from continuous use.
Touch Screen Care and Cleaning
The touch screen requires very little maintenance. 3M Touch Systems recommends that
you periodically clean the glass touch screen surface.
CAUTION
To reduce the risk of the potentially hazardous situations associated with the use of
isopropyl alcohol which may result in minor or moderate injury or property
damage:
Follow all instructions and recommendations in the alcohol manufacturer's Material
Safety Data Sheet and product label.
Typically, an isopropyl alcohol and water solution ratio of 50:50 is the best cleaning
agent for your touch screen. You can also use straight isopropyl alcohol. In addition, 3M
Screen Cleaner CL680 has been tested and approved for this use. Be sure to follow
solvent manufacturer's precautions and directions for use when using any solvents.
• It is important to avoid using any caustic chemicals on the touch screen.
• Always dampen the cloth and then clean the screen. Be sure to spray the cleaning
liquid onto the cloth, not the screen, so that drips do not seep inside the display or
stain the bezel.
• Apply the cleaner with a soft, lint-free cloth. Avoid using gritty cloths.
• Always handle the touch screen with care. Do not pull on or stress the touch screen
cable.

CHAPTER 1
Getting Started
The MicroTouch™ ToughTouch II touch screen is the one of the most intuitive interfaces
available for the PC today. Touch screens make using computers as simple as touching
the screen. To begin installing your ToughTouch II touch screen, take a few minutes to
review this chapter. It is your roadmap to a successful installation.
• Pay close attention to the important safety information. Disassembling a display can
be a dangerous procedure. Be sure to follow all manufacturers' recommendations for
assembly and disassembly of your flat screen display.
• Make sure you have the necessary equipment before starting the installation. Refer to
Supplies and Tools Needed for the Installation later in this chapter.
• Set up a clean, comfortable, and spacious working area. Having sufficient room to
work makes the installation easier.
• Test your display to ensure good working condition before you install the touch
screen.
• Identify the different components to install and review the summary of the
installation procedure. It is important to know how all the pieces eventually fit
together before disassembling your system.
Note: If any points within this guide are unclear to you, or further clarification is
necessary, please contact your 3M Touch Systems applications engineer.
Installation Information
3M Touch Systems recommends that only qualified display technicians install the touch
screen.
If you decide to install the touch screen, take the following precautions:
• Follow each procedure carefully, work with the system powered off and unplugged,
and observe all safety information.
