8 Troubleshooting
8.1

Weak battery

Provided that the voltage value permits it, the wall-mount
remote control will remain ready for operation also 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 pe-
riod.
If the voltage drops too far during transmission, this will
be displayed on the device or via the Homematic IP app
(see sec. „8.4 Error codes and flashing sequences" on page
46). In this case, replace the empty batteries by two new
batteries (see sec. „7 Replacing batteries" on page 42).
8.2

Command not confirmed

If at least one receiver does not confirm a command, the
device LED lights up red at the end of the failed transmis-
sion process. The failed transmission may be caused by
radio interference (see sec. „11 General information about
radio operation" on page 49). This may be caused be
the following:
• Receiver cannot be reached.
• Receiver is unable to execute the command (load
failure, mechanical blockade, etc.).
• Receiver is defective.
