Error messages

10.1

Weak battery

If the batteries are weak, the respective error code (see Changing
the batteries) is shown.
If the batteries are so weak that a reset is triggered several times
in a row without transmitting successfully, no transmission will
be made for following button presses and the LED will only be
illuminated in red for 0.5 seconds.
10.2

Command not confirmed

If a receiver does not confirm a command (at least one when
more than one have been taught), the device LED is illuminated
in red when the transmission is complete. The error will then be
found with the receiver:
• Receiver not accessible
• Receiver cannot execute command (load failure, me-
chanical blockage, etc.)
• Defective receiver

Maintenance and cleaning

The product is maintenance-free besides possibly requiring a
battery change. Maintenance or repairs are only to be done by
trained professionals. Clean the product using a soft, clean, dry
and lint-free cloth.
To remote heavier contamination, make the cloth damp with
lukewarm water. Cleaning agents that contain solvents are not to
be used because it can harm the plastic housing and the labels.
