3.3 Displays
3.3.1 Mains indicato r
The ”Mains indicator” symbol lights up when 230V mains voltage is being applied to the 12V
charging system. The batteries are charged.
The display is only shown when the 12V supply for the leisure area is switched on (”12V
ON”).
3.3.2 Battery voltag es
The 12V supply for the leisure area must be switched on for the display (see section 3.1).
 T urn the encoder until the ”Leisure battery” symbol lights up.
F The ”V olt” scale lettering lights up.
F The voltage of the leisure battery is displayed on the LED scale for approx. 20 se-
conds.
The following display function only exists for motorhomes because caravans have no vehicle
battery.
 T urn the encoder until the ”Starter battery” symbol lights up.
F The ”V olt” scale lettering lights up.
F The voltage of the starter battery is displayed on the LED scale for approx. 20 se-
conds.
CAUTION!
Batteries (regardless of type) can be damaged permanently, possibly beyond repair, when
fully discharged. So therefore:
F Avoid low battery charge (indicated by low voltage)
F Check the voltage regularly (see section 3.3.2)
It is best to carry out checks in the morning before 12V consumers are switched on.
The following table shows how to correctly interpret the leisure battery voltage.
