Replacing batteries
If an empty battery is displayed via the app or the device (see
„8.3 Error codes and flashing sequences“ on page 39), re-
place the used batteries by two new LR6/mignon/AA batteries.
You must observe the correct battery polarity.
To replace the batteries of the passage sensor, please proceed
as follows:
•
Slightly press the catch on the side of the device and
remove the electronic unit
(A)
from the cover
(E)
to
open the battery compartment cover
(C)
(
see fig. 3
).
•
Remove the empty batteries from the battery com-
partment
(C)
.
•
Insert two new LR6/mignon/AA batteries in the battery
compartment, observing the polarity shown
(see fig. 6).
•
Reattach the cover.
•
Please pay attention to the flashing signals of the de-
vice LED while inserting the batteries (see „8.3 Error
codes and flashing sequences“ on page 39).
Once the batteries have been inserted, the passage sensor will
perform a self-test/restart (approx. 2 seconds). Afterwards, in-
itialisation is carried out. The test display
(D)
will indicate that
initialisation is complete: orange and green lighting.
