   • Sound: This locomotive is sound-ready. If equipped with a sound decoder, various sound functions (e.g., horn, bell, engine sounds) can be activated via your DCC controller's function buttons (F1-F28, depending on the decoder). Consult your DCC system's manual and the decoder's specific documentation for function mapping.
