Using this Martin moving light is easy. First, connect it to the correct power supply that comes with the product. Plug it in and turn it on to start using it. When it comes to placement, make sure it's in a stable position where it can shine light effectively. As for maintenance, keep the light clean by gently wiping it with a soft, dry cloth. Check the lamp regularly, and if you notice a significant decrease in brightness or if it stops working, it might be time to replace the lamp. Even though the display menu screen has scratches, it still works fine. Just be careful when using the menu not to apply too much pressure. And always remember to turn off the power before any maintenance work to ensure your safety.
