8.6.1 Switching the 12 V power supply on/off
The rotary knob (Fig. 134,5) switches the panel and the 12 V power supply
to the living area on and off.
Exception: Heater, basic light (lighting in the entrance area), entrance step
and the refrigerator are always ready to operate.
Press the rotary knob (Fig. 134,5): The 12 V living area power supply is
switched on. The 12 V indicator lamp (Fig. 134,4) lights up.
Press the rotary knob (Fig. 134,5): The 12 V living area power supply is
switched off. The 12 V indicator lamp (Fig. 134,4) goes off.
When leaving the vehicle, switch off the main 12 V power supply at the
rotary knob. This prevents any unnecessary discharge of the living area
battery.
Appliances, such as control units (e.g. solar charge regulator, defroster
or panel) or fitted appliances (e.g. heater, refrigerator or step) continue
to take power from the battery capacity, even if the 12 V power supply
on the panel is switched off. Therefore disconnect the living area battery
from the 12 V power supply via the switch on the transformer/rectifier if
the vehicle will not be used for a long period of time.
8.6.2 Battery voltage display
The panel shows the battery voltage of the entire battery system. If the
vehicle has a
HYMER
Smart Battery System (special equipment), a fur-
ther display panel is installed. You can read the exact voltage values on
this additional display panel.
The battery voltage will be displayed for approx. 20 seconds after it has
been called up.
Use the rotary knob (Fig. 134,5) for reading the voltage of the living area
battery as well as that of the starter battery. The voltage is displayed on the
indicator scale for battery voltage (Fig. 134,1).
Turn the rotary knob (Fig. 134,5) until the symbol for the desired battery
lights up.
