CARE OF YOUR MARANTZ PROJECTION TV
• IGNITION NOISE:
Black spots or horizontal streaks may appear, picture may flutter or drift. Usually caused by
interference from automobile ignition systems, neon lamps, electrical drills and other
electrical appliances.
• GHOSTS:
Ghosts are caused by the Rear Projection Television signal following two paths. One is the
direct path and the other is reflected from tall buildings, hills or some other objects. Changing
the direction or position of the antenna may improve reception. Ghosting may also be
caused by defects in the antenna system such as unshielded leads or connecting several
sets to the same antenna without using multiple antenna couplers.
• SNOW:
If your receiver is located in the fringe area of a television station where the signal is weak,
your picture may be marred by the appearance of small dots. When the signal is extremely
weak, it may be necessary to install a special antenna to improve the picture.
• RADIO FREQUENCY INTERFERENCE:
The interference produces moving ripples or diagonal streaks and in some cases, causes
loss of contrast in the picture.
NOTE: The Rear Projection Television can generate sound distortion in external devices such as a radio. Please separate radio
equipment from the Rear Projection Television to a considerable distance.
NOTE: The Rear Projection Television has the nature that some pixels do not always work correctly. That is, some are lit and
some are not. This is not a problem.
SCREEN
The screen surface is easily scratched. Do not rub, touch or
tap it with sharp or abrasive objects. Be especially careful
when transporting the Rear Projection Television.
PANEL
Do not expose the screen to direct sunlight. It may damage
the panel. When the Rear Projection Television is used in a
cold place, the image may look lengthened. This is not a
malfunction. The image will become normal when the
temperature rises.
When the same static picture has been displayed continuously,
an afterimage impression of that picture may remain on the
screen. This will disappear after a certain period of time.
If you turn on the Rear Projection Television immediately after
power has been restored at an interruption, burn may occur.
This is not a malfunction. The image will become normal after
a certain period of time.
MOISTURE CONDENSATION
If the Rear Projection Television is transported directly from a
cold to a warm location or if the room temperature has changed
suddenly, the picture may be blurred or show poor color. This is
because moisture has condensed on the lenses inside. If this
happens, let the moisture evaporate before using the Rear
Projection Television.
