No voltage module is installed in the standard version.
Warning: Do not open the batteries. Do not bring
batteries into contact with water or expose to tem-
peratures above 80 °C. Dispose of used batteries at
suitable collection points.
In the 110 V AC and 230 V AC versions a cable is fitted at the
factory leading outwards which must be connected to the net-
work voltage indicated. The 24 V ACDC version has connec-
tion terminals instead of a cable.

comes to a noticeable stop.

In order to free up the appropriate battery compartment,
move the red locking hatch accordingly.
Note: Left compartment for 2× AA-cells or 1× C-cell,
right compartment for 1× D-cell.
