Using the Barco HDX - W14 projector is easy. First, connect it to the correct power supply that comes with it. Make sure to place it in a well - ventilated area to avoid overheating. When using, connect your device to the projector via appropriate cables. For maintenance, keep the projector clean. You can use a soft, dry cloth to wipe the exterior. When the lamp reaches the end of its estimated remaining runtime of 2572 hours, you'll need to replace it. Remember, this projector doesn't come with a lens, so you'll need to use your own if required.
