HOW TO SET UP YOUR NEW HITACHI PROJECTION TV
ANTENNA
Unless your TV is connected to a cable TV system or to a centralized antenna system, a good outdoor color TV
antenna is recommended for the best performance. However, if you are located in an exceptionally good signal
area that is free from interference and multiple image ghosts, an indoor antenna may be sufficient.
LOCATION
Select an area where sunlight or bright indoor illumination will not fall directly on the picture screen. Also, be sure
that the location selected allows free flow of air to and from the perforated back cover of the set.
To avoid cabinet warping, cabinet color changes, and increased chance of set failure, do not place the TV where
temperatures can become excessively hot, for example, in direct sunlight or near a heating appliance, etc.
VIEWING
HOOK-UP CABLES AND CONNECTORS - 9 -
The major benefit of the HITACHI Projection Television is its large viewing screen. To see this large screen at its
best, test various locations in the room to find the best spot for viewing. The drawings giver several suggestions.
The best picture is seen by sitting directly in front of the TV and about 10 to 18 feet from the screen. Picture
brightness decreases as the viewer moves to the left or right of the receiver.
During daylight hours, reflections from outside light may appear on the screen. If so, drapes or screens can be
used to reduce the reflection or the TV can be located in a different section of the room.
If the TV's audio output will be connected to a Hi-Fi system's external speakers, the best audio performance will
be obtained by placing the speakers equidistant from each side of the receiver cabinet and as close as possible to
the height of the picture screen center. For best stereo separation, place the external speakers at least 4 feet from
the side of the TV. Place the surround speakers to the side or behind the viewing area. Differences in room sizes
and acoustical environments will require some experimentation with speaker placement for best performance.
CAUTION: The magnetic field of external speakers may cause the TV picture to distort if the
speakers are placed too close to the television. Move the speakers away from the TV until there is no picture
distortion.
HOOK-UP CABLES AND CONNECTORS
Most video/audio connections between components can be made with shielded video and audio cables that have
phono connectors. For best performance, video cables should use 75-Ohm coaxial shielded wire. Cables can be
purchased from most stores that sell audio/video products. Below are illustrations and names of common
connectors. Before purchasing any cables, be sure of the output and input connector types required by the
various components. Also make sure the cables are the correct length.
