DIAGNOSTICS softkey

The Diagnostics screen contains three tabs:

• READINGS tab
• TESTS tab
• ABOUT tab

READINGS tab

This tab will display operating voltages, part numbers, and hours of operation.

TESTS tab

This tab will allow the user to perform 3 different screen calibrations—Color Test, Touchscreen Test, Touchscreen Calibration.

The main function under the tests tab will be Touchscreen calibration. Touchscreen calibration will be required when the screen icon does not align with the area depressed. This may be caused by normal wear and tear, age, certain weather conditions, and contaminants on the screen (chemicals, solvents, etc.).

Touchscreen Calibration:

1. Under the Touchscreen Calibration button a new screen will appear with an X in the upper right corner.

2. Press the screen at the X and continue to follow the X’s around the screen. Always press the screen directly at the center of the X.

3. Several X’s will show up at various locations on the screen.

4. Continue to press at the center of the X until complete.

Reset Touchscreen calibration will abort any saved calibrations and allow the user to start over and perform a new calibration.

Color Test:

Under the Test button, select the color test. The color test will display 3 distinct colors on the display for approximately 5 seconds. If you do not see 3 distinct colors, contact your John Deere Dealer for service.

Touchscreen Test:

Under the Test button, select the Touchscreen Test. This test will allow the user to identify a pixel problem on the screen.

1. As you touch the screen, a sighting target will show up on the area touched.

2. Continue to touch the screen around the area of suspected pixel malfunction and see if the sighting target appears.

If sighting target does not appear, contact your John Deere Dealer.
