Please take a moment to review this manual, it will help ensure you many years of trouble-free service from your new Stewart Filmscreen product. About your ABT-EM Trapdoor ElectriMask Electriscreen Your ABT-EM ElectriMask Electriscreen offers the most technologically advanced trapdoor roller screen in the world. The hingeless door is powered by its own motor. Sound dampers ensure quiet operation. The ElectriMask system is designed to integrate with the latest multi-format video projectors, which are capable of variable sizes and aspect ratios for viewing standard broadcast television and the wide format seen in commercial theaters (“letterbox”). The term aspect ratio refers to the format (width to height) in which your home cinema sources are produced. Your screen is equipped with either a vertical masking system to achieve a 1.33:1 aspect ratio (see Figure 1) or a horizontal masking system to achieve a 1.85:1 aspect ratio (see Figure 2). Figure 1: Vertical masking system 1.85:1 Format Screen Converts to 1.33:1 Standard Video NTSC Format Figure 2: Horizontal masking system 1.85:1 Format “Letterbox” 1.33:1 Standard Video NTSC Format Converts to Stewart Filmscreen Corporation PREPARING THE INSTALLATION • Before proceeding with the installation of this screen, take time to thoroughly read and understand these installation and operation instructions. • All electrical wiring installations must conform to local and national codes and should be performed by qualified service personnel. • There are no user-serviceable parts contained within the unit. Preparation Specifications regarding the individual screen dimensions, weight, mounting type, and controls are provided by the factory when the unit is ordered. Before beginning the installation: • Check the specifications for the type of mounting and switch control to be used. • Ensure that the mounting area and electrical connection are prepared. • Check the size and weight of the screen to be installed so that you can plan for the number of people required for the mounting procedure.
