Introduction
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.
Installation
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.

CLEANING AND MAINTENANCE
CLEANING AND MAINTENANCE

Cleaning
Occasionally clean the display panel and cabinet with a soft cloth dampened (not soaked)
with a mild (non-abrasive) glass cleaner. Keep turning a fresh side of the cloth toward the
screen surface to avoid scratching it with accumulated grit.
Note:
The solvent should be applied only to the cloth, and not directly on the monitor screen.
Do not use paper products as they may scratch the surface. To minimize the risk of
abrasion, allow the screen to stand dry.
Special care should be taken when cleaning a touch screen or polycarbonate shield that is
installed over the screen. Abrasive and certain chemical cleaners can easily damage the
surface.
Never use alcoholic or ammoniac cleaners to clean the polycarbonate shield or a touch
screen.
Replacing a Line Cord
To avoid shock and fire hazards, the monitor’s power cord should be replaced if the
insulation becomes broken or if it develops a loose internal connection.
Other Maintenance
Qualified service personnel should perform all maintenance, except for the power cord
replacement described above.
