7-5-11-1 Calibration
NOTE: Always try TP calibration verification before attempting to calibrate.If the Touch Panel is so far
out of calibration, hangs or does not calibrate and the normal calibration procedure does not
work, it may be necessary to do a complete Pre-calibration.
To do a Touch Screen Calibration, follow the directions on the Touch Screen. As each of the cross-hairs
appear, touch them with your finger or a pencil eraser.
NOTE: You MUST hold your finger on the cross-hair until it moves to the next location. If you just tap
the calibration cross-hair, there is a good chance your calibration will be corrupt.

Calibration Verification

The Start Touch Screen Verification brings up a grid. Each time you touch the screen a small red dots
appears where you touch, this will indicate that the calibration is correct and you do not need to
re-calibrate.
If the red dots do not show up at the touched places, you need to run the Touch Panel calibration. To
terminate the verification, move the trackball pointer into the grid and press the set key.
