Batteries
In many countries, the ARC2 ships without batteries due to safety regulations. If this is the case for
you, please buy 2 Alkaline AA batteries and insert them in the correct positioning with + and – posi-
tioned correctly. Do not use rechargeable batteries as they do not work stable.
When closing the battery compartment push each corner until the compartment cover sits in the
right position. Then close the slider to fix the battery compartment in a closed position.
