Johdanto
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.
Asennus ja asennus
1. Purkaminen
- Avaa pakkaus varovasti ja poista kaikki osat.
- Inspect the screen and frame for any signs of damage. If damage is found, contact customer support immediately.
- Ensure all parts listed in the packing list (refer to your product packaging) are present.
2. Seinäasennus
The Spectra Projection Helios screen is designed for wall mounting. Professional installation is recommended due to the size and precision required for optimal viewing.
- Valitse sijainti: Choose a flat wall surface free from obstructions. Ensure the wall can support the screen's weight (approximately 30 pounds).
- Mittaa ja merkitse: Determine the desired height and center point for the screen. Use a level to mark the positions for the mounting brackets according to the provided template (if included) or measurements in the assembly guide.
- Asenna kiinnikkeet: Securely attach the wall mounting brackets to the marked positions using appropriate hardware for your wall type (e.g., wall anchors for drywall, screws for studs).
- Assemble Frame (if required): Follow the separate assembly instructions for the screen frame.
- Attach Screen Material: Carefully attach the screen material to the frame, ensuring it is taut and wrinkle-free.
- Kiinnitä näyttö: With assistance, lift the assembled screen and carefully hook it onto the installed wall brackets. Ensure it is securely seated and level.

3. Projektorin sijoittelu
This screen is specifically designed for Ultra Short Throw (UST) projectors. The projector must be placed directly below the screen, very close to the wall, projecting upwards onto the screen surface. Refer to your projector's manual for exact placement distances and keystone correction settings.

Käyttöohjeet
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 viewkokemusta.
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 viewing.

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.

Huolto
Cleaning the Screen Surface
- Pölynpoisto: Gently wipe the screen surface with a soft, dry, lint-free microfiber cloth to remove dust.
