Command not confirmed

If at least one receiver does not confirm a command, the
device LED (A) lights up red at the end of the failed trans-
mission process. The failed transmission may be caused
by radio interference (see „1 Information about this man-
ual" on page 27). 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.
