Description
The tap sound can be set to mute, low or loud from "Volume &
Sounds" on the Control Panel
Tap on the screen and then hold the contact to display a pop-up
menu relevant to the tapped object.
When screen rotation display is used with the display function, the
coordinates of the touch panel will also flip in unison.
Disables touch panel input.
The unit is equipped with a calibration function for coordinate
correction. Set data for calibration is saved to flash disk when the
Welcome wizard runs on first startup, and when calibration is run by
pressing the "Fn + 4" keys. Therefore, even if the batteries run
down, there is no need to run calibration again. The touch panel
calibration may drift due to deterioration over time, voltage
fluctuation temperature change, etc.
If it does, re-calibrate the touch panel settings.
