WARNING

This projection television receiver was intended mainly for the private viewing of programs broadcast by TV stations and cable companies and programs from other video sources. Public viewing may require prior authorization from the broadcaster or owner of the video program.

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

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 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.

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 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

an antenna adaptor (300-Ohm to 75-Ohm). For connecting RF signals (antenna or cable TV) to the antenna jack on the television.

Used on all standard video and audio cables which This connector is used on camcorders, VCRs, connect to inputs and outputs located on the and laser disc players with an S-Video feature Television's front and rear jack panels. in place of the standard video cable to produce a high-quality picture.

ANTENNA CONNECTIONS

VHF (75-) antenna/CATV(cable TV)

When using a 75-ohm coaxial cable system, connect the outdoor antenna or CATV coaxial cable to the VHF/UHF 75-ohm terminal.

VHF (300-) antenna/UHF antenna

When using a 300-ohm twin lead from an outdoor antenna, disconnect the VHF or UHF indoor antenna leads from screws of the VHF or UHF adaptor, and connect outdoor VHF or UHF antenna leads to these screws of the VHF or UHF adaptor.

When both VHF and UHF antennas are connected

Attach an optional ANT. MIXER (antenna cable mixer) to the TV antenna terminal, and connect the cables to the ANT. MIXER. Consult your dealer or service store for the ANT. MIXER.
