Gas operation with internal
batteries (optional)
An optional battery compartment in the
electronics case for internal (self-contained)
power supply of the electronics is available
for the model variants RM 8xx1 and RM 8xx5
(appliances with electronics).
Battery compartment

Load the battery compartment with batteries
(8 x AA 1.5 V) before operating the refrigerator.
Fig. 18
All operating modes can be selected while the
on-board 12 V DC power supply is active. The
internal voltage is disconnected.
If the 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 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 internal batteries.
The GAS LED flashes every 15 seconds. If a
button is pressed, the temperature level LEDs
(7) also light.
If the battery voltage is too low, an acoustic
signal (whistle tone) sounds every 15 seconds.
Then replace the batteries in the battery
compartment.
Inserting / changing the batteries
