Important Instructions for Using the Touch Screen (for Touch

Model Only)

• 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.

• Regularly clean the retro-reflective bars with a clean, soft cloth. A dusty environment

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.
