SAFETY POINTS YOU SHOULD KNOW ABOUT
YOUR HITACHI LCD REAR PROJECTION
TELEVISION
Our reputation has been built on the quality,
performance, and ease of service of HITACHI
televisions.
Safety is also foremost in our minds in the design of
these units. To help you operate these products
properly, this section illustrates safety tips which will be
of benefit to you. Please read it carefully and apply the
knowledge you obtain from it to the proper operation of
your HITACHI television.
Please fill out your warranty card and mail it to
HITACHI. This will enable HITACHI to notify you
promptly in the improbable event that a safety problem
should be discovered in your product model.
Follow all warnings and instructions marked on
this television.
The lightning flash with arrowhead symbol,
within an equilateral triangle, 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 a
person.
The exclamation point within an equilateral
triangle, is intended to alert the user to the
presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.
READ BEFORE OPERATING EQUIPMENT
Follow all warnings and instructions marked on this
television.
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any ventilation openings. Install in
accordance with the manufacturer's instructions.
8. Do not install near any heat sources such as
radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two
blades with one wider than the other. A grounding
type plug has two blades and a third grounding
prong. The wide blade or the third prong are
provided for your safety. If the provided plug does
not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
10. Protect the power cord from being walked on or
pinched particularly at plugs, convenience
receptacles, and the point where they exit from the
apparatus.
11. Only use the attachments/accessories specified by
the manufacturer.
12.
Use only with the cart, stand, tripod,
bracket, 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 recommended 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 protection 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 grounding 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
provided to call the CATV system installer's attention to
Article 820-44 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 Projection Television
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
using your LCD Rear PTV against a wall, keep it at least 10cm (4 inches) from the wall.
NOTE: Your new HDTV has a built-in high definition television signal processor. This television includes a fan
to cool the processor. The sound of moving air from the fan is normal and may be noticeable in very
quiet environments.
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.
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.
