Important instructions for using the touch screen
• You can calibrate the touch screen using the Windows 7 calibration routine.
• Do not bend the retro-reflective bars. The touch screen cannot function normally if the
bars are bent.
• Keep the touch screen out of direct sunlight or spotlights.
• Avoid displaying still images to prevent image retention.

may adversely affect the performance of your touch screen. Clean the retro-reflective
bars as illustrated below. Do not clean the touch sensors on the top of the screen.
• The function described in this section only applies to Windows 7 - Home Premium,
