11. Troubleshooting
11.1 Low battery capacity
If the voltage allows, the window and door contact will also be
operational when the battery capacity is low. Depending on the load,
after a brief battery recovery period, the signals may be transmitted
again multiple times.
If the voltage fails again during transmission, this will be indicated in
the SilverCrest Smart Home app and on the device (see Section "11.4
Error codes and flash sequences"). In this case, replace the empty
batteries immediately with two new batteries of the same type, in
order to guarantee safe operation (see Section "10. Changing the
batteries").
11.2 Command not confirmed
If at least one receiver does not confirm a command, the device LED
(C) will turn red at the end of the faulty transmission. The faulty
transmission may be due to radio interference (see Section "14.
General information on radio interference"). Possible causes of the
faulty transmission are:
Receiver batteries are dead
The receiver cannot be reached
The receiver cannot carry out the command (load failure,
mechanical blockade etc.)
The receiver is faulty.
