Using this model is straightforward. You can operate it on a DC layout as it's been programmed for that. Just connect it to the appropriate power source and start running it on your track. When it comes to the SoundTraxx Tsunami DCC decoder, if the audio is too faint, you might want to check and replace the speaker or the audio circuit. Be careful when handling the model because it's made of brass and can be fragile. Avoid dropping it or hitting it against hard surfaces. For maintenance, keep it clean. You can use a soft, dry cloth to wipe off any dust. If there's dirt on the wheels, clean them gently. Store it in the original box and foam when not in use to protect it from damage. If you have any issues with the lighting, you may need to check the wiring. And remember, if you're not satisfied with your purchase, you can return it within 30 days for a full refund, but you'll need to cover the return shipping costs unless the item arrives damaged.
