Batteries are not included !
Load the battery compartment with batteries
(8 x AA 1.5 V) before operating the refrigerator.
Self-contained gas operation
All operating modes can be selected while the
on-board 12 V DC power supply is active. The
battery compartment is disconnected from the
power supply.
If the vehicle on-board 12 V DC power supply
is not present or there is an interruption of the
mains power supply during operation, the
electronics automatically switch to the appli-
ance internal battery power supply.
The refrigerator can now only be operated
in the gas mode.
All LED indicators except the GAS LED are not
lit during operation with the batteries inside
the appliance. The GAS LED flashes every 15
seconds.
If a button is pressed, the temperature level
LEDs (7, Fig. 8) also light.
If the voltage of the battery inside the applian-
ce is too low, an acoustic signal (whistle tone)
sounds every 15 seconds.
Then replace the batteries in the battery com-
partment
