Touchscreen Calibration
If a touchscreen is attached to the Annotator, the touch accuracy should be calibrated
using the Calibrate Panels setting in the Advanced configuration menu.
Both RS-232 and USB connected touchscreens require calibration.
To calibrate a connected and powered-on panel, do the following:
1. Press the Menu button on the front panel of the Annotator repeatedly until reaching
the Advanced Configuration menu.
2. Within the Advanced configuration menu press Next repeatedly to cycle to Calibrate
Panels Press Size.
3. Press Size and observe the touchpanel screen. A cross appears in the upper left corner.
4. Tap the screen at the cross, and the cross then moves to the top right corner.
5. Tap the cross in the top right corner. This moves the cross to the bottom right corner.
6. Tap the cross in the bottom right corner. This moves the cross to the bottom left
corner.
7. Tap the cross in the bottom left corner. The unit now saves the calibration data and
restarts the sequence.
8. Repeat the process for each connected touchscreen.
9. Press any Annotator front panel button to exit the sequence and save the data.
