හැඳින්වීම
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.
සැකසුම සහ ස්ථාපනය
1. ඇසිරීම
- ඇසුරුම් ප්රවේශමෙන් විවෘත කර සියලුම සංරචක ඉවත් කරන්න.
- 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. බිත්ති සවි කිරීම
The Spectra Projection Helios screen is designed for wall mounting. Professional installation is recommended due to the size and precision required for optimal viewing.
- ස්ථානය තෝරන්න: Choose a flat wall surface free from obstructions. Ensure the wall can support the screen's weight (approximately 30 pounds).
- මිනුම් සහ ලකුණු: 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.
- වරහන් ස්ථාපනය කරන්න: 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.
- තිර ද්රව්ය අමුණන්න: Carefully attach the screen material to the frame, ensuring it is taut and wrinkle-free.
- Mount Screen: With assistance, lift the assembled screen and carefully hook it onto the installed wall brackets. Ensure it is securely seated and level.

3. ප්රොජෙක්ටර් ස්ථානගත කිරීම
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.

මෙහෙයුම් උපදෙස්
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 viewඅත්දැකීමෙන්.
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.

නඩත්තු කිරීම
තිර මතුපිට පිරිසිදු කිරීම
- දූවිලි ඉවත් කිරීම: Gently wipe the screen surface with a soft, dry, lint-free microfiber cloth to remove dust.
- ස්ථාන පිරිසිදු කිරීම: 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.
- රසායනික ද්රව්ය වලින් වළකින්න: Never use harsh chemicals, solvents, alcohol-based cleaners, or abrasive materials on the screen surface, as these can damage the optical layers.
- පීඩනය: Do not apply excessive pressure when cleaning, as this can cause permanent damage or distortion to the screen material.
සාමාන්ය සත්කාර
- Avoid touching the screen surface directly with bare hands.
- Keep the screen away from direct sunlight or strong heat sources when not in use, if possible, to prevent material degradation.
- Ensure the screen is not exposed to sharp objects that could scratch or puncture the surface.
