Using this Barco HDF - W26 projector is easy. First, connect the 30A 250V twist - lock power supply to a suitable power source. Make sure to use the correct power supply that comes with the projector. Since the lens is not included, you'll need to install your own lens before use. When using, keep an eye on the lamp hours. With 171 hours already used and 23% usage, you have about 582 hours of remaining lamp runtime. For maintenance, try to keep the projector in a clean and dry place. Also, be aware that the cart in the photo is not included, so you'll need to find a proper way to move and store the projector.
