I have just purchased a new loco which DCC sound (ESU Decoder), when the loco is going forward the rear lights are on when in reverse the front lights are on. Looked through the operating manual can’t find any instructions to reset, Also unable to change from 03 to my own number, the loco is a Scale trains Rivet counter model. Can anyone help would be very much appreciated
