8.1 Weak battery
Provided that the voltage value permits it, the key ring re-
mote 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 battery voltage is too weak, this will be displayed in
the Homematic IP app and directly on the device via the
device LED
(A) (see „8.4 Error codes and flashing sequenc-
es“ on page 36). In this case, replace the empty battery
by a new one (see „7 Changing battery“ on page 32).
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 (depending on the reason, the LED can light
up with a delay of up to 10 s). The failed transmission may
be caused by radio interference (see „11 General informa-
tion about radio operation“ on page 39). This may be
caused by the following:
• Receiver cannot be reached.
• Receiver is unable to execute the command (load
failure, mechanical blockade, etc.).
• Receiver is defective.
