Important Information Please read the following information on using and maintaining the projection TV, for optimum viewing quality. Picture quality • Poor color registration (the red, green and blue signals do not overlap properly) may be caused by the influence of the earth's magnetism. Correct this with the CONVERGENCE adjustment (pp. 26 - 27). • Avoid touching the screen, and take care not to scratch the surface with hard objects. • Leaving a fixed pattern on the screen for long periods of time, when operating a video game or personal computer, may damage the picture tube. To avoid this, keep the picture contrast and the brightness levels low (PICTURE and BRIGHT adjustment, pp. 50 - 51). Illumination To obtain a clear picture, do not expose the screen to direct illumination or direct sunlight If possible, use spot lighting directed down from the ceiling. Cover the windows that face the screen with opaque drapery. • The floor and walls should not be of a light-reflecting material. If necessary, cover them with dark carpeting or wallpaper. Installation • To prevent internal heat built-up, do not block the ventilation openings. • Do not install the projection TV in a hot or humid place, or in a place subject to direct sunlight, excessive dust or mechanical vibration. pw • Avoid operating the projection TV at temperatures below 5°C (41°F). 5 • After transporting the projection TV directly from a cold to a warm location, or if the room temperature has changed suddenly, pictures may be blurred or show poor color over portions of the picture. This is because moisture has condensed on the mirrors or lenses inside the projection TV. Let the moisture evaporate before using the projection TV. • Avoid placing the projection TV on a slanted or uneven floor. After setting up, adjust the levelling legs to stabilize the projection TV (p. 2). Maintenance • Save the original shipping carton and packing material to use if you ever have to ship your projection TV. For maximum protection, repack your projection TV as it was originally packed at the factory. • To keep the cabinet looking brand-new, periodially clean it with a soft cloth. Stubborn stains may be removed with a cloth slightly dampened with a mild detergent solution. Never use strong solvents such as thinner or benzine, or abrasive cleansers since these will damage the cabinet As a safety precaution, unplug the projection TV before cleaning it. • To remove dust from the front of the screen, unplug the projection TV and wipe it gently with a soft cloth slightly dampened with water or a mild detergent solution, using vertical strokes only. Then wipe it again with a dry, soft cloth. Never use solvents or thinners for cleaning purposes. • If the picture turns dark after the projection TV has been in use for a long period of time, it may be necessary to clean the inside of the projection TV. Consult qualified service personnel for this. I5 Preface
