Additional features for the module from manufacturer Lenz,
The radio receiver can control up to 4 wireless controls.
Up to 9999 digital locomotive addresses are available.

Switching of hands and feet is also possible.
Switching of points and signals.
Important note for use on analogue locomotives:
Analog locomotives controlled by Lenz digital systems, generate a whistling sound.
This is normal, as the DC current varies constantly on the track (which is not usually dealt with by a decoder on an analogue locomotive, as it is applied directly to a motor).
Not suitable for locomotives with a bell motor (Faulhaber for example). This type of model is only agreed for use on digital systems.
.
Without a receiver, these motors would be damaged and could cause overheating in a short time. If in doubt, please refer to the manufacturer associated with your motrix.
