Changing battery Troubleshooting
Button “light” (E):
Switches individually defined lights with a brief button
press on or with a long button press o (e.g. in connec-
tion with the Homematic IP Pluggable Switch).
7 Changing battery
If the battery symbol is displayed via the app or an emp-
ty battery is indicated on the device (see sec. „8.4 Error
codes and flashing sequences“ on page 35), replace
the used battery by a new LR03/micro/AAA battery. Please
observe the correct battery polarity.
To replace the battery of the key ring remote control,
please proceed as follows:
• Open the battery compartment (H) at the rear
by pushing the battery compartment cover away
from the device. You will need to apply some
pressure to do this (see figure 2).
• This will open the catch and the battery compart-
ment cover can be opened (the cover remains
attached to the housing).
• Insert a new 1.5 V LR03/micro/AAA battery into
the battery compartment, making sure that it is
the right way round (see figure 4).
• Close the battery compartment by swinging the
battery compartment cover back on. Push the
cover towards the centre of the housing (apply-
ing a little pressure) until it latches into place.
Once the battery has been inserted, the key ring remote
control performs a self-test (approx. 2 seconds). After-
wards, initialisation is carried out. The LED test display
will indicate that initialisation is complete by lighting up
orange and green
(see sec. „8.4 Error codes and flashing
sequences“ on page 35)
.
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.
8 Troubleshooting
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 battery has been allowed a brief recovery period.
If the battery voltage is too weak, this will be displayed
in the Homematic IP app and directly on the device via
