Troubleshooting
Never recharge standard batteries. Do not throw
the batteries into a fire. Do not expose batteries to
excessive heat. Do not short-circuit batteries. Do-
ing 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.

Troubleshooting
7.1
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
„7.4 Error codes and flashing sequences" on page 42).
In this case, replace the empty batteries by two new bat-
teries (see „6 Replacing batteries" on page 38).
7.2
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 trans-
mission process. The failed transmission may be caused
by radio interference (see „10 General information about
