CARING FOR YOUR HD PROJECTION DISPLAY

Your HD Projection Display will look better, have a longer
life and perform better if you care for it properly.
First check to see that the HD Display is off.
For added safety, disconnect AC power to the
HD Display.
Note: If you unplug your HD Display, you will
have to reset the clock to the current time.

CABINET CARE

Non-Wood Cabinet or Cabinet Components. Moisten a soft
cloth with a mild soap solution. Wipe the surface with a
damp cloth. Then rinse the cloth in clean water and wipe
the surface again. Allow the HD Display to air-dry before
turning it on.

LENS CLEANING

When the lenses of your HD Projection Display need clean-
ing, be sure to follow these directions so you do not dam-
age or scratch the optical coating on the lenses:
• Do NOT spray any type of fluid directly on
the lenses' surface.
• Use a soft cotton cloth (cotton diapers
laundered several times to remove sizing) or a
soft facial tissue.
• Do NOT use any type of aerosol cleaner.
• Do NOT use dry material, such as paper,
tissue or a dry cloth to clean the lenses.

EXTENDED ABSENCE

Before an extended absence (such as a vacation) you may
want to disconnect AC power to your HD Display. This will
protect the HD Projection Display from possible damage
from lightning or power line surges. For added safety, you
may want to disconnect all video equipment currently con-
nected to the HD Display.
Note: If you unplug your HD Display, you will have to reset
the clock to the current time.

PICTURE INTERFERENCE

Your picture may be affected by interference caused by one
or a number of factors, including:
Speckled or Streaked Picture - Can be caused by nearby
automobile ignition, electrical appliances, etc. This is most
noticeable when there are loose connections to the unit.
Snow in Picture - Caused by insufficient signal - possibly
when the video cable is too long or broken, or has an
intermittent ground return.
