Using this Athearn Genesis EMD GP9 model is easy. Just place it on your HO scale track and power it up. In DC mode, you can enjoy basic engine, horn, and bell sounds. For more functions, switch to DCC mode. When programming multiple units (MU), make sure to follow the instructions to set up the lead unit's horn, bell, and lights.
