Installing the Decoder
Before you install the decoder, you must make sure
that the locomotive is in excellent electrical and me-
chanical condition. Defects or dirt must be removed
and fi xed before trying to install the decoder. In all ca-
ses you must pay attention to the general information
provided by the manufacturer of the locomotive.
Remove the bridge plug installed in the locomotive
and plug the decoder in its place into the connector.
Pay attention to the installation position for the deco-
der when you do this.
Solder contacts are made on the decoder for the SUSI
connector and for locomotives with the 8-pin connector.
Caution:
You must exercise extreme caution when doing
soldering work on the decoder. Damages caused by
incorrect soldering procedures cannot be accepted
as a reason for warranty claims.
