How to use

Mount the screen securely on a suitable wall or support following the included mounting points and local installation guidelines. Pull the front tab or bottom bar gently to extend the viewing surface to the desired length; the internal latch will hold the screen in place. To retract, release the latch mechanism as indicated in the product documentation and allow the screen to roll back slowly into its housing. Ensure the surface is clean and free from dust before projecting to maintain image clarity.

Recommendations

For optimal results, position the projector so that its lens is perpendicular to the screen surface to reduce keystone distortion. Use ambient lighting control to improve perceived contrast on the white surface; dim lights or use directional lighting when projecting images with fine detail. Regularly inspect the mounting hardware and the screen housing for secure installation and safe operation.
