Specifications

Using this Athearn HO scale SD39 locomotive is a breeze. First, make sure you have a compatible power source. If you're using DC power, the engine, horn, and bell sounds will work just fine. For more functions, switch to DCC mode where you can access full DCC features. To start the engine, use the sound decoder to trigger the startup sound sequence. You can control the lighting functions with F5 and F6 buttons. When programming a multiple - unit (MU) lashup, remember that only the lead unit's horn, bell, and lights will be in use. As for maintenance, keep the locomotive clean. You can gently wipe the body with a soft cloth. Check the wheels regularly to make sure they're clean and not stuck. Avoid getting water or other liquids on the electrical components. If you're adding grime or rust to the primed - for - grime model, use appropriate modeling paints and techniques. And always follow the safety instructions, especially since this product is recommended for ages 14 and up.
