Using this model is easy. Just connect it to a DC Analog power source. Since the PFM Sound is installed, you might want to test it out, but remember it hasn't been tested before. When handling, be gentle as it's a fragile brass model. For maintenance, keep it clean and store it in the original box and foam when not in use. If you notice any issues with the motor or gears, don't try to fix it yourself. Contact us, and we'll help you out. And if you're not satisfied with your purchase, let us know within 30 days for a full refund, though you'll be responsible for return shipping unless the item arrives damaged.
