You calibrate the touch panel the first time you run

If you see a cross cursor on the screen, you should tap the center of
the cursor to calibrate the touch panel, or you can abort the
calibration with the

key.
Five cursors will appear on the screen in turn.
Once calibration is done,
Nm
saves the calibration parameters into the database file and uses the saved
parameters to calibrate the touch panel.

You can run
Nm
automatically with
Pa /etc/rc.d/tpctl .

calibration.
