Using the battery monitor

The device is equipped with a multi-level battery monitor that protects your vehicle
battery against excessive discharging when the device is connected to the on-board
DC supply.
If the cooler is operated when the vehicle ignition is switched off, the cooler switches
off automatically as soon as the supply voltage falls below a set level. The cooler will
switch back on once the battery has been recharged to the restart voltage level.
