Temperature Warning
The touch display contains a temperature sensor that can monitor the system temperature. If the touch display is
operated outside the specified temperature range, it will go into Thermal Protection mode. In this mode, the
brightness will be reduced in order to bring the system temperature back within the specified temperature range.
The brightness will not be able to be increased beyond the set value. After five minutes of use within the normal
temperature range, the touch display will automatically restore the brightness level back to what it was set at
previously. If the touch display is continuously operated outside the specified temperature range, it will shut off after
a 60 second on-screen timer.
