Overheating detection
The device is equipped with temperature sensor, if the temperature is too high, the
LED screen can become dark or suspend operation to protect the internal circuit.
When the temperature drops, it will recover automatically and will operate normally.
If overheating is detected, cool down the temperature inside the car with air-con or
by opening the window.
The device may not recover due to sudden change of temperature, so do not force
the cooling down using coolant or ice.

installed at the front of the monitor, and auto-adjust the brightness
to the optimum level using the DIMMER function provided.
