Replacing batteries
• Remove the empty batteries.
• Insert two new 1.5 V LR03/micro/AAA batteries
into the battery compartment, making sure that
you insert them the right way round (see fig. 7).
• Please pay attention to the flashing signals of the
device LED while inserting the batteries (see „7.4
Error codes and flashing sequences" on page
38).
• Put the cap back to the electronic unit.
Once the batteries have been inserted, the window /
door contact will perform a self-test (approx. 2 seconds).
Afterwards, initialisation is carried out. The LED test
display will indicate that initialisation is complete by
lighting up orange and green.
Caution! There is a risk of explosion if the battery
is not replaced correctly. Replace only with the
same or equivalent type. Never recharge standard
batteries. Do not throw the batteries into a fire.
Do not expose batteries to excessive heat. Do not
short-circuit batteries. Doing so will present a risk
of explosion.
Used batteries should not be disposed of with
regular domestic waste! Instead, take them to
your local battery disposal point.
