HOW 1O SL1 UP YOUR NEW HITACHI COLOR TV

ANTENNA

Unless your TV Jscu_, _uctedto a cable TV system or to a centralized antenna system, a good outdoor color TV antenna is recommended for the best performance. However, ifyou 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 a free flow of air to and from the 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 Color Television is its

viewing screen. To see this 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 6 to 9 feet from the screen.

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 ex- perimentation with speaker placement for best perfor-

mance.

I _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 bythe various components. Also make sure the cables are the correct length.
