Connecting the STI To Projector or AC power source Optional 12 VDC transformer with switch Automatic Vertical Screen: Owner’s Manual 7 ADJUSTING THE SCREEN EXTENSION The extension and retraction limit switches have been preset at the factory. In general, we advise you to avoid readjusting these switches. In rare cases, to enable proper alignment of the displayed image on the screen, you may need to adjust the extension of a screen. If adjustment to the extension is necessary, carefully follow these instructions. Keep in mind that incorrect adjustment can cause faulty operation. Modifying the extension of the screen It is possible to decrease the preset extension of a screen up to 3" (7.6 cm). Do not attempt to modify a screen extension more than this recommended amount. Do not increase the extension. The limit switches are located on audience right of the case. .. The white limit switch adjusts the extended (open) screen position. .. The yellow limit switch adjusts the fully retracted (closed) position. Do not adjust this switch. To decrease the screen extension: 1. Ensure that the screen is in its fully retracted position, but with the door open to access the limit switches. 2. Locate the white limit switch located on the audience right side of the case. Use a screwdriver to turn the switch in a clockwise direction. Note: One complete turn of the switch will make approximately a 3/4" (2 cm) change in the screen’s stop position. 3. Activate the screen until it reaches the newly reduced stop position. Once you have made the adjustment, whenever you extend the screen, it will automatically stop at the new position. Caution Improper adjustment of the limit switches can cause irreparable damage to a screen itself, resulting in voiding the factory warranty. The yellow limit switch retracts the screen further into the case. Adjusting it is not advised. Incorrect adjustment of the limit switch can cause the arms to lock. Be sure the screen retracts fully or the door will close on it, and damage the screen. Yellow (do not adjust) White (adjusts open screen position) Figure 5. Limit switches SCREEN CARE AND CLEANING With reasonable care, you can expect many years of trouble-free use of your Stewart projection screen. We encourage you to keep your screen clean. To protect your screen when it is not in use, store it in the fully retracted position. Avoid getting any foreign material on the screen, as cleaning may prove very difficult. It may not be possible to remove scratches, paint, ink, etc. General maintenance Cautions • Do not use chemicals or solvents to clean the fabric. • Do not allow debris or particles to fall into the screen housing. The surface of your screen is delicate. Special attention to these instructions should be followed when cleaning. • A draftsman-style brush may be used to lightly whisk away any loose dirt or dust particles. (This type of brush is usually available at office supply stores.) Stewart Filmscreen has an optional screen cleaning kit that contains the proper type of brush. Contact your dealer if you would like to obtain this cleaning kit. • Particles left on the screen when it is retracted into the case may form an impression on the screen surface. Periodically wipe the back of the screen with a clean damp cloth. • For tougher spots, use a solution of mild detergent and water. Rub lightly using a sponge. Blot with a damp sponge to absorb excess water. Residual water marks will evaporate within a few minutes. Let the screen air dry completely before retracting. Do not use any other cleaning materials on the screen. Contact the factory if you have questions about removing difficult spots. Replacement parts and service No user-serviceable parts are contained within the unit. Contact your dealer or the factory if you require part replacement or service.
