9.8.2 Battery alarm for the living area battery
The red ALARM warning light (Fig. 137,8) flashes as soon as the voltage of
the living area battery falls below 11 V (measured under operation) and there
is a risk of a total discharge.

1)
The battery guard switches all the appliances off (at 10.5 V).
2)
If the voltage does not exceed this range for several hours.
Values for off-load voltage Charging condition of the battery

12.3 V 50 %
12.5 V 75 %
More than 12.8 V Full
Total discharge causes irreparable damage to the battery.

Only read the tank levels briefly. Keeping the reading option on for a long
time can damage the transducers.
When the battery alarm comes on, switch off the appliances and charge the
