Rev 1.3
7.2.4 To complete the total system grounding for the overlay and enclosure/kiosk, please review the
following:
a) The enclosure/kiosk, enclosure door, and other overlay mounting system
components must all share a single point electrical ground connection with the
overlay.
b) Installer/technician must determine the best location and method of grounding the
enclosure, enclosure door, and other enclosure components as well as the overlay/monitor
chassis attached to a single AC power ground connection.
7.2.5 After the overlay and enclosure/kiosk are grounded, the 80-point touch screen will need to be
reset due to the change in its overall sensing environment:
a) Unplug the touch overlay’s USB cable from the PC or media player.
b) Leave the overlay’s USB cable unplugged for 10 to 15 seconds.
c) Plug the overlay’s USB cable back into the PC.
d) Wait for approximately 10 to 15 seconds for the system to reset, then test the touch
functionality.
7.2.6 Touch overlay hardware grounding is complete. Enjoy your new touch capabilities!
7.2.3 Using a #2 Philips screwdriver, remove the factory screw in the top right corner of the monitor
chassis. Secure the other end of the grounding wire to the monitor using the provided M3x10
pan head screw, as shown in figure 8c. The overlay is now grounded to the monitor chassis.
