Calibrating the Touch Screen

With a clear desktop on the computer:

1. Run the Touch Screen Tools by clicking its icon in the system tray or Windows Control Panel.

2. Make sure the computer desktop is clear.

3. Click the [Calibrate] button on the Touch Screen Tools. The mouse pointer moves automatically to a position at the top left of the screen.

4. Touch and hold your finger (or stylus) on the screen at that position until the pointer moves.

5. The pointer moves to three further positions in sequence—top right, bottom right, bottom left—touch each point in turn until the pointer moves.

This completes the touch screen calibration procedure.

NOTE:

When removing your finger, lift it straight off the screen, making sure you don't drag it across the screen.

NOTE:

Test the calibration by moving the mouse pointer around the screen checking that it closely follows your finger.

NOTE:

If the calibration is not satisfactory, you can re-calibrate.

NOTE:

Make sure your finger is placed accurately at each calibration point.

Diagnostic Test

This option on the Touch Screen Tools runs a diagnostic test on the touch screen and displays one of the following three messages:

screen and try again. If problem persists call

Using the cleaning cloth supplied, clean the screen and surrounding area inside the

bezel gently taking care to avoid cameras located on the top left and right corners of

the screen. Re-run the diagnostic test again after cleaning.
