How do I Recalibrate the Touch Screen on my Vantage and Vanguard?
Over time you may notice that the icons and images on the device's screen do not speak the correct message for the icon you selected. This is normal with a touch screen and can be easily fixed by recalibrating
To Recalibrate the Display:
NOTE: You must be in a Unity overlay, the Toolbox or a Custom Page to recalibrate your screen. You cannot do this from a menu.
1. On the top front of the case, press and hold the TOOLS key while you activate the last USER DEFINED key on the far right of the case (the key that was pre-programmed as the SET-UP key).
2. Release both keys.
3. You will see a cross + in the middle of a blank screen.
4. With a stylus, a pen cap, or the eraser end of a pencil, press on the cross + and hold for 3 seconds. Lift stylus. The cross will move to the upper left section of the screen.
5. Press and hold the stylus on the cross + again, then release.
6. Repeat this until the cross+ has traveled to all five points on the screen (the center and all four corners).
7. If the calibration is successful, you will see a message at the top of the screen that tells you "New Calibration Settings have been measured. Tap the Screen to register saved data." Tap the screen once before the 30 seconds expires.
8. If the device recognizes the tap, the screen will return you to the Toolbox or wherever you started from.
9. If you do not see the message in step 7, repeat these directions.
Reasons the Touch Screen may need to be Recalibrated:
1. You used your battery pack until there was no charge left in it.
2. Your battery pack was unplugged.
Important Note: You can put a HOLD on these calibration settings by going to the Toolbox, then to Maintenance Menu, then to Hardware Diagnostics. Now enter the Touch Screen test. Press the TOOLBOX key on the top of the case 5 times. You now will hear 6 beeps in return. This verifies that your new calibration settings have been stored, so if your device looses power or is reset, you should not have to recalibrate your device.
