6 Troubleshooting
6.1 Command not confirmed
If at least one receiver does not confirm a command,
the device LED
(B) lights up red at the end of the failed
transmission process. The failed transmission may be
caused by radio interference (see “1 Information about
this manual” on page 35). The failed transmission may
also be caused by the following:
• Receiver cannot be reached.
• Receiver is unable to execute the command (load
failure, mechanical blockade, etc.).
• Receiver is defective.
