Using this projection screen is easy. First, during the rough - in stage of your construction, install the case where you want your screen to be. When the finish stage arrives, install the fabric assembly. To operate the screen, use the Decora style 3 - button wall switch or the Low Voltage Control. For those with advanced control needs, the built - in SCB - 100 and SCB - 200 (RS - 232 serial control board) can be used. When it comes to maintenance, keep the screen away from sharp objects to avoid scratches on the fabric. Wipe the white powder - coated case with a soft, dry cloth to maintain its clean look. Make sure the installation area is well - ventilated as the UL Plenum Rated case ensures safety even in high - air - flow areas. If you notice any issues with the tension, don't try to adjust it on your own; contact the manufacturer for professional help. Enjoy your high - quality projection experience with this Da Lite screen!
