ATTENTION:
Soldering on the decoder should only be carried out by experienced professionals with the appropriate
tools. For decoders that have been damaged by improper handling, the warranty claim is void.
A short circuit in the area of motor, lighting and power consumption
destroys the building block and possibly the electronics of the locomotive!
