Using your EIKI LC - HDT2000 projector is easy. First, make sure you have a compatible power source (remember, it doesn't come with a power cable, so you'll need to provide your own). Connect the projector to your source device, like a laptop or DVD player. Adjust the focus and zoom to get a clear image on the screen. When it comes to lamp usage, keep an eye on the hours. Lamp 1 is locked in eco - mode, which can save energy but may also affect brightness. Check the filter counter regularly. If it reaches a high number, it might be time to clean or replace the filter. Always turn off the projector properly after use to avoid damage. Store it in a cool, dry place when not in use.
