The alarm functions are only active when the corresponding display is
called up. Perform checks regularly.
It is best to perform checks in the morning, before the 12 V appliances are
switched on.
Total discharge damages the battery.
If the battery voltage falls below 10.5 V, the battery monitor in the trans-
former/rectifier switches off all of the 12 V appliances, excluding the safety/
drainage valve.
