CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT REMOVE COVER (OR BACK).
NO USER SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
The lightning flash with arrowhead symbol, within an equilateral tri-
angle, is intended to alert the user to the presence of uninsulated
“dangerous voltage” within the product’s enclosure that may be of a
sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle, is intended to
alert the user to the presence of important operating and mainte-
nance (servicing) instructions in the literature accompanying the
appliance.
NOTE: • There are no user serviceable parts inside the television.
• Model and serial numbers are indicated on back side of the television.
POWER SOURCE
THIS TELEVISION IS DESIGNED TO OPERATE ON 120 VOLTS 60Hz, AC CURRENT. INSERT THE
POWER CORD INTO A 120 VOLT 60Hz OUTLET.
TO PREVENT ELECTRIC SHOCK, DO NOT USE THE TELEVISION’S (POLARIZED) PLUG WITH AN
EXTENSION CORD, RECEPTACLE, OR OTHER OUTLET UNLESS THE BLADES AND GROUND TERMI-
NAL CAN BE FULLY INSERTED TO PREVENT BLADE EXPOSURE.
NEVER CONNECT THE TELEVISION TO 50Hz, DIRECT CURRENT, OR ANYTHING OTHER THAN THE
SPECIFIED VOLTAGE.
CAUTION: Never remove the back cover of the television as this can expose you to very high voltages and other haz-
ards. If the television does not operate properly, unplug the television and call your authorized dealer or
service center.

where they exit from the apparatus.
11. Only use the attachments/accessories specified by the man-
ufacturer.
12. Use only with the cart, stand, tripod, brack-
et, or table specified by the manufacturer,
or sold with the apparatus. When a cart is
used, use caution when moving the
cart/apparatus combination to avoid injury
from tip-over.
13. Unplug this apparatus during lightning storms or when
unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing
is required when the apparatus has been damaged in any
way, such as power-supply cord or plug is damaged, liquid
has been spilled or objects have fallen into apparatus, the
apparatus has been exposed to rain or moisture, does not
operate normally, or has been dropped.
15. Televisions are designed to comply with the recommended
safety standards for tilt and stability.
Do not apply excessive pulling force to the front, or top, of the
cabinet which could cause the product to overturn resulting
in product damage and/or personal injury.
16. Follow instructions for wall, shelf or ceiling mounting as rec-
ommended by the manufacturer.
17. An outdoor antenna should not be located in the vicinity of
overhead power lines or other electrical circuits.
18. If an outside antenna is connected to the receiver be sure the
antenna system is grounded so as to provide some protec-
tion against voltage surges and built up static charges.
Section 810 of the National Electric Code, ANSI/NFPA No.
70-1984, provides information with respect to proper ground-
ing for the mast and supporting structure, grounding of the
lead-in wire to an antenna discharge unit, size of grounding
connectors, location of antenna-discharge unit, connection to
grounding electrodes and requirements for the grounding
electrode.
Note to the CATV system installer: This reminder is provid-
ed to call the CATV system installer’s attention to Article 820-
40 of the NEC that provides guidelines for proper grounding
and, in particular, specifies that the cable ground shall be
connected to the grounding system of the building, as close
to the point of cable entry as practical.

HOW TO SET UP YOUR NEW HITACHI LCD REAR PTV
5
ANTENNA
Unless your LCD Rear PTV is connected to a cable TV system or to a centralized antenna system, a good outdoor TV antenna is
recommended for 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.
When installing your LCD Rear PTV against a wall, keep it at least 10 cm (4 inches) from the wall.
VIEWING
The major benefit of the HITACHI LCD Rear PTV is its large viewing screen. To see this large screen at its best, test various locations
in the room to find the optimum spot for viewing.
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 and 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 four 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.
FIRST TIME USE
IMPORTANT NOTES:
1. Since LCD Rear PTV incorporates a high pressure lamp to display an image, it may take about one minute for the picture to
become stable, after the power has been turned on. After extended use, the picture may darken, the color may look unusual,
or the lamp “goes out,” (burns out). You may hear a “pop” sound when the lamp “goes out.” These are common
characteristics of the lamp, and should not be considered defective.
2. LCD Rear PTV incorporates an advanced cooling fan system to prevent from overheating. If you hear the cooling fan, it should
not be considered defective.
3. If you hear a “cracking” sound from the TV cabinet, it is due to the TV’s cabinet expanding and contracting due to room
temperature changes. It has no effect on the TV’s functions.
4. The LCD Rear PTV cabinet is constructed with all plastic. Make sure to place it on a flat surface. An uneven surface might
warp the cabinet and reduce the picture quality.

ANTENNA CONNECTIONS TO REAR JACK PANEL
VHF (75-Ohm) antenna/CATV (Cable TV)
When using a 75-Ohm coaxial cable system, connect the outdoor antenna or CATV
coaxial cable to the ANT A (75-Ohm) terminal. If you have a second antenna or
cable TV system, connect the coaxial cable to the ANT B terminal.
VHF (300-Ohm) antenna/UHF antenna
When using a 300-Ohm twin lead from an outdoor antenna, connect the VHF or
UHF antenna leads to screws of the VHF or UHF adapter. Plug the adapter into
the antenna terminal on the TV.
When both VHF and UHF antennas are connected
Attach an optional antenna cable mixer to the TV antenna terminal, and connect
the cables to the antenna mixer. Consult your dealer or service store for the
antenna mixer.

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 and the length of each cable.
300-Ohm Twin Lead Connector
This outdoor antenna cable must be connected to an antenna
adapter (300-Ohm to 75-Ohm).
Phono Connector
Used on all standard video and audio cables which connect to
inputs and outputs located on the television’s rear jack panel
and front control panel.
“F” Type 75-Ohm Coaxial Antenna Connector
For connecting RF signals (antenna or cable TV) to the antenna
jack on the television.
S-Video (Super Video) Connector
This connector is used on camcorders, VCRs and laser- disc
players with an S-Video feature in place of the
standard video cable to produce a high quality picture.
Digital Visual Interface (DVI) Connection Cable
This cable is used to connect external devices with DVI-HDTV
output capability.
