All equipment, cables, and connectors used with the special-application receptacle must be assembled by qualified electronic personnel All circuits connected electrically to the projector through this receptacle must have a rating of not more than 30 V (rms) and must comply with Underwriters Laboratories, Inc., low-voltage, limited energy circuit requirements.1
To project single slides, slide the power switch to a half- or full-lamp position. Remove the tray and insert a slide upside down into the projector gate. Push the slide all the way down.
After viewing the slide, press forward, reverse, or the select bar to eject the slide.
When buying a lens, consider features such as focal length (measured in millimetres), aperture (designed as an f/stop), and the lens design (curved or flat).
When selecting a lens, remember that the shorter the focal length (i.e., the smaller the f/number), the brighter the projected image. Also, a curved-field lens, in combination with cardboard open face mounts from an automated mounting process, provide superior projection quality. A flat-field lens is the best choice for glass-mounted slides.
