- Blurry Image: Adjust the focus ring on the projector lens until the image is sharp.
- Trapezoidal Image: Use the manual keystone correction to adjust the image shape.

- Cleaning the Casing: Wipe the projector's casing with a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water, then wipe dry.
