4 Touch screen recalibration
The touch screen should not require calibration unless there are problems when trying to select
objects on the screen. In this case the touch screen can be recalibrated as follows:
Touch screen

The touch screen calibration is started by pressing the recessed button on the top of the unit with
a small pointed object.
Figure 22: An example of a calibration screen showing the target
After pressing this button the screen will change to a blank display with a small target on it similar
to the one shown in Figure 22. Using a small blunt pointed object, touch the screen at the area
indicated until prompted to release. This will be repeated a number of times after which the system
will display a prompt for the calibration to be accepted. Accept this prompt to continue.
After calibrating the screen the system should be shut down and restarted by pressing the power
button briefly and then clicking 'Yes'. If this is not done then the system may not save the screen
calibration settings.
