I have an ICE 2 36711 with the station announcement and horn functions. They work with a Mobile Station. But I recently got an old Central Station 1 and am still learning how it works. When I entered the loco into the CS1 as 36711, none of the sound functions seem to work. The light function works fine. How can I change the CS1 settings to get the sound to work? (All my MFX locos work just fine with the CS1.)
