9.2 Command not confirmed

If a receiver (at least one in cases where multiple
devices have been taught in) does not confirm a com-
mand, the device LED lights up red at the end of the
transmission process. This behaviour may be caused
by the following:
• The receiver cannot be accessed.
• The receiver is unable to execute the command
(load failure, mechanical blockade, etc.).
• The receiver is defective.
