If the screen calibration is out on your HEMA Navigator HN6, that is it registers the screen tap in the incorrect position, it can be rectified by doing the following:
From the Main Menu of your HEMA Navigator:
Tap the Tools icon. This will take you to the Settings screen.
Tap the Calibration icon - You will be asked to confirm that you wish to calibrate the screen:
Tap OK to confirm, or Cancel if you change your mind.
The calibration screen will be displayed. There will be black cross-hairs in the center of the screen. Tap as closely as you can to the center of the cross-hairs using the stylus (do not use your finger, unless you have very small pointy fingers!)
The cross-hairs will then move to the top-left of the screen
Tap the cross-hairs at top-left. They will then move to a position at lower-left of the screen. Again, tap as closely as you can to the center of the cross-hairs.
Continue this process following the cross-hairs around the screen in an anti-clockwise direction.
Once the cross-hairs at upper-right have been tapped, the Settings screen should be automatically displayed again.
Use the back arrow to return to the main screen.
Your screen is now calibrated.
