Passap 6000 mechanical use?

Hello, help please, I bought a Passap 6000 machine but while I learn and connect some cables that were cut I want to use it mechanically trying to use the duomatic manual which is more specific than the 6000, the problem is that the letters change, the previous version has ABC on the front carriage while the 6000 has k,l,c... thank you very much!
