AW: In order to protect ZENEC devices against under voltage and resulting malfunctions such as software crashes or even damage to the electronics, the ZENEC device has an automatic under voltage check while the device is booting up and during device operation: If the supply voltage is unstable or fluctuating, dropping below 10.5 volts, the device triggers a restart.
Device restarts usually point at the on-board power supply, which can briefly drop below 10.5 volts during engine start. If the device frequently restarts/reboots when the engine is started, it is best to consult the service partner or motorhome dealer to have the starter battery and/or electrical installation checked.
