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. 24 > 25).
• Avoid touching the screen, and take care not to scratch
the surface with hard objects.
• Displaying a still picture for long periods of time, for
instance, when using the FREEZE function (p. 42) or
when operating a video game or personaU computer, may
damage the picture tube. To avoid this, keep the picture
contrast level low (PICTURE adjustment, pp. 44 - 45).
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.
The floor and walls should not be of a light>reflecting
material. If necessary, cover them with dark carpeting or
wallpaper.

5*C (41 »F).
• After transporting the projection TV directly from a cold to
a wann location, or if the room temperature he» changed

floor.

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
