Once the batteries have been inserted, the device will perform a self-test
for approx. 2 seconds. Afterwards, initialisation is carried out. The LED
test display will indicate that initialisation is complete by lighting up or-
ange 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 re-
charge non-rechargeable batteries. Do not throw the batteries into
a fire. Do not expose batteries to excessive heat. Do not short-cir-
cuit batteries. There is a risk of explosion
Used batteries should not be disposed of with regular domestic
waste! Instead, take them to your local battery disposal point.

Troubleshooting
8.1
Weak batteries
Provided that the voltage value permits it, the device will remain ready for
operation even if the battery voltage is low. Depending on the particular
load, it may be possible to send transmissions again repeatedly once the
batteries have been allowed a brief recovery period.
If the voltage drops too far during transmission, this will be displayed on
the device or via the Homematic IP app (see „8.4 Error codes and flashing
sequences" on page 30). In this case, replace the empty batteries by
two new batteries (see „7 Changing the batteries" on page 28).
8.2
Command not confirmed
If at least one receiver does not confirm a command, the device LED
(A) lights up red at the end of the failed transmission process. The failed
transmission may be caused by radio interference (see „11 General infor-
mation about radio operation" on page 32). This may be caused by the
following:
•
Receiver cannot be reached.
•
Receiver is unable to execute the command (load failure, me-
chanical blockade, etc.).
•
Receiver is faulty.
