SAFETY TIPS

PROTECTION AND LOCATION OF YOUR SET

16-I. If an outside antenna is connected to the televi-

sion set, be sure the antenna system isgrounded

so as to provide some protection against voltage surges and built up static charges, Section 810 of

the National Electrical Code, NFPA No. 70-1975,

provides inforrr_t_ with respect to proper

grounding of the mast and supporting structure,

OPERATION OF YOUR SET

19. This television set should be operated only from the type of power souroe indicated on the marking

label If you are not sure of the type of power

supply atyour home, consult your televisiort dealer

or local power company. For television sets

designed to operate from battery power, refer to the operating instructions.

tion of antenna discharge unit, connection to grounding electrode, and requirements for the

grounding electrode.

16-2.

Note to CATV system installer:. (Only for the television set with CATV reception)

This reminder is provided to call the CAW sys- tem installer's attention to Article 820-40 of the

NEC that provides guidelines for proper ground- ing and, in particular, specifies that the cable

ground shall be connected to the grounding sys- tem of the building, as close to the point of cable

entry as practical.

17.

An outside antenna system should not be located in the vicinity of overhead power lines or other

electrical lights or power circuits, or where it can fall into such power lines or circuits. When

installing an outside antenna system, extreme

care should be taken to keep from touching such

power lines or circuits as contact with them might be fatal.

18.

For added protection for this television set dudng a lightning storm, orwhen it is left unattended and

unused for long periods of time, unplug it from the wall outlet and disconnect the antenna. This will

prevent damage due to lightning and power-line surges.

WARNING

manent damage to projection television

receivers. Such "PATTERN BURNS" con-

stitute misuse and are NOT COVERED by your Hitachi Factory Warranty.

When using the Picture-in-Picture function, the sub-picture should not be left permanently

in one corner of the screen or a "pattern burn" may develop over a long period of time.

HOW TO SET UP YOUR NEW HITACHI PROJECTION TV

ANTENNA

Unless your TV is connected to a cable TV system or to acentralized antenna system, a good outdoor color "IV 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 a 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 ofthe HITACHI ProjectionTelevision is

itslarge viewing screen. To see this screen at itsbest,test

various locations in the room to find the best spot for

viewing. The drawings give several suggestions.

The best pictureisseen by sittingdirectly in front of the "IV and about 10 to 18 feet from the screen. Picture bright-

ness decre,_ses as the viewer moves to the left or rightof the receiver.

During daylighthours, reflectionsfrom outsidelight may appear onthe screen. If so,drapes or screenscan be

usedto reducethe reflectionortheTV canbe locatedin a differentsectionofthe 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 ofthe receiver cabinet and as close as possible

to the height of the picturescreen center. For best stereo

separation, place the external speakers at least 4 feet from the side ofthe 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.

4' MINIMUM
