Touch Panel Calibration
The display screen uses a touch sensitive membrane. This means that every location of the entire surface of the display is touch sensitive. This diagnostic allows alignment of these touch locations with the location of the buttons images on the screen.
Normally this should never need adjustment, and is used only to adjust the touch locations for parallax (the touch locations appear different when viewed at an angle). However, if an adjustment is necessary, follow this procedure:
- The screen consists of the + button icons. Touch the center of the five + buttons on order 1-5.
- To store any change you make, touch the Set button.
- Use the Return key to exit the diagnostic.
