AW: Zenec devices include under-voltage monitoring circuitry to avoid low voltage boot processes, safeguarding the unit electronics that may not work as intended without stable supply voltage. The root cause of device reboot issues can usually be attributed to the on-board batteries or power supply network cables and connections, causing the voltage to drop below 10.5 volts during engine start-up.
In case of frequent device reboots after engine starts, please consult your vehicle service point or the motor home dealer to review your car´s starter or second battery and the electrical wiring.
