Introdução
This manual provides comprehensive instructions for the setup, operation, maintenance, and troubleshooting of your Spectra Projection Helios Fresnel ALR Projector Screen. Designed for ultra short throw (UST) projectors, this 120-inch screen utilizes advanced Fresnel Ambient Light Rejecting (ALR) technology to deliver bright and vivid images even in well-lit environments.
Please read this manual thoroughly before installation and use to ensure optimal performance and longevity of your projector screen.
Configuração e instalação
1. Desembalagem
- Abra cuidadosamente a embalagem e remova todos os componentes.
- Inspect the screen and frame for any signs of damage. If damage is found, contact customer support immediately.

Instruções de operação
The Spectra Projection Helios screen is a passive display surface. Its operation is directly linked to your Ultra Short Throw projector. Ensure your projector is correctly aligned and calibrated for the best viewexperiência.
Ambient Light Rejection (ALR) Technology
The screen features advanced Fresnel ALR technology. This specialized optical surface is engineered to reflect light from the UST projector directly to the viewer while absorbing or deflecting ambient light from other angles. This results in a bright, high-contrast image even in rooms with significant ambient light, making it suitable for daytime viewindo.

8-Layer Optical Surface Structure
The screen's performance is enhanced by an 8-layer optical surface structure. Each layer contributes to image quality, color accuracy, and durability. These layers include anti-glare, color plane, diffusion, columnar, speckle diffusion, Fresnel, reflecting, and blackened layers, working in concert to optimize the projected image.

Manutenção
Cleaning the Screen Surface
- Remoção de poeira: Gently wipe the screen surface with a soft, dry, lint-free microfiber cloth to remove dust.
- Limpeza de manchas: For smudges or fingerprints, lightly dampen a clean microfiber cloth with distilled water. Wipe the affected area gently in one direction. Do not rub vigorously.
- Evite produtos químicos: Never use harsh chemicals, solvents, alcohol-based cleaners, or abrasive materials on the screen surface, as these can damage the optical layers.
