Operation and Maintenance
This mobile decoder is maintenance free.
Its live is mainly determined by the electrical
and mechanical condition of the locomotive.
Therefore you should regularly change the
motor brushes.
Installing the Decoder into a
Loco without NEM-Plug
If your loco is not equipped with a NEM-Plug
you have to cut the plug off the decoder and
solder the wires directly to the contacts of the
locomotives.
Colours of the wires:
red
- track 1
black - track 2
orange - motor 1
grey
- motor 2
white - headlights 1
yellow - headlights 2
blue
