AW: To protect the device electronics from under voltage conditions and resulting malfunction of function modules inside the device the ZENEC mainboard and the MCU constantly measure the power supply voltage via sensor, to trigger a shut-down (and reboot) if the supply voltage drops below 9 V. The automatic sense process avoids faults on the device operation and incomplete loading of software data. This is a self-protection function of the device and not a defect.

If the device does frequently reboot after engine starts it is recommended to see the car dealership for an inspection of the battery and or, if wires and contacts are corroded to cause supply voltage drop below 9V.
