HOW TO SET UP YOUR NEW HITACHI PROJECTION TV
HOOK-UP CABLES AND CONNECTORS - 10 -
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
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 give
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 receiver'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.
NOTE: 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
ANTENNA CONNECTIONS - 11 -
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.
300-Ohm Twin Lead Connector "F" Type 75-Ohm Coaxial
This outdoor antenna cable must be connected to Antenna Connector
