MAIN POWER SWITCH, 12 V SYSTEM
The living area’s 12 V system has a main power switch
with a key.
This main power switch cuts the supply from the battery.
This de-energises all the living area’s functions.
When the motorhome is not being used, turn the main
power switch off. This saves the battery and thus reduces
the risk of it running flat.
When the main power switch is turned on, the electri -
cal system begins a start-up procedure that takes a few
moments. The living area’s electrical functions cannot be
used before completion of the start-up procedure.
If the motorhome is connected to 230 V, the living area’s
battery and the vehicle’starter battery will be charged even
if the main power switch is off.
ALARM ON ENGINE START
The electrical system gives an alarm if the engine is star-
ted while:
• 230 V AC is connected; or,
• the antenna is in the extended position.
There is an audible alarm and the corresponding alarm
icon shows on the control panel.
