the sides of the electronic unit and pull it from the

the batteries.
• Insert two new 1.5 V LR6/mignon/AA batteries into
the battery compartment, making sure that you
insert them the right way round
(see figure 14) .
• Place the electronic unit back into the mounting
plate (see figure 12) .
• Please pay attention to the flashing signals of the
device LED while inserting the batteries (see “9.4
