TOUCH SCREEN CALIBRATION

IMPORTANT: Before proceeding with any touchscreen repairs
you should ensure the display is thoroughly cleaned as per the
notes in installation guide. This must include cleaning around the
bezel area using compressed air. Dust in this bezel area is a
common cause of touchscreen failures .
From time to time the touchscreen on Tango may need to be re-calibrated. In
particular if you notice that it is hard to select items on the screen accurately, it is
time to re-calibrate the touchscreen. Follow the steps below to re-calibrate the
touchscreen.
If you have the "Touchscreen Properties window already open (or you wish to
open it from the control panel as shown in the preceding section) you can
continue by clicking the Calibrate button on this panel as shown below.
Otherwise, perform the calibration from the Tango software as follows:-
• Select the "System" menu tab on the LHS of the display.
• Select "Operating System" from the System Menu
• Select "Calibrate Touch" from the System Menu to open the "Touchscreen
Properties".
