HOW TO SET UP YOUR NEW
HITACHI DLP
TM
ANTENNA
Unless your Rear Projection TV is connected to a cable TV system or to a centralized antenna system, a good outdoor color 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 Rear Projection 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 Rear Projection Television 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 Rear Projection 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 Rear Projection TV can be located in a different section of the room.
If the Rear Projection 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 Rear
Projection 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.

Notes
This set has a 200W lamp. The lamp rarely breaks. If it does, it will make a pop noise.
It takes time (17 seconds) to display picture on television compared to a conventional color tele-
vision. LED at the front panel indicates the set is under power on condition. (See note on page 8)
It takes about 60 seconds for the picture to re-appear, after quickly pressing power OFF
then ON again. Three LEDs indicate the set is under power on condition. On: Three LED's
blink alternately. Off: One LED blinks.
Fans will keep working for about 2 minutes after power OFF to cool down the lamp.
ness (This is not a guarantee that life time of a lamp is 4000 hours).
This set has fixed pixel elements. There may be some dark/bright spots on the
element. However, this is not a defect.
Please set proper signal strength. You may see streaks in picture on some channels without
proper antenna. Streaks may disappear when signal is strong. Place antenna and cable
away from the AC power cord.
Due to varying signal content, you may see vertical or horizontal lines bend occasionally in
PC mode. However, this phenomenon is not a defect. It's caused by a lack of picture content
due to under-scanning in PC mode.
This set provides the best picture quality in SVGA mode. It is recommended that you set your
PC to SVGA mode. In OVERSCAN mode, top/bottom icon will be approximately 19% to 50%
within the viewable area, and should be accessible to grab and click. Picture is overscanned
when receiving XGA or higher resolution signals.
Please do not leave the TV set with still pictures like games, stock market qutoes, and other
non-moving pictures. Otherwise it may cause a pattern burn on the screen.
When the lamp is cooling down, the remote control does not respond within 15 seconds. LED at
the front panel shows if your set accepts remote commands. When blinking is slow, your set is
ready to accept remote commands.
There is a color wheel spinning at high revolution in the television set. It may be broken if you
move your set before setting power off.
The television CPU sets picture blanking to hide unnecessary noise, until it becomes stable.
OSD position/size change according to the picture aspect format, when watching a component
(Y-P B P R ) signal. SDTV (480P): OSD aspect changes when screen format is changed. HDTV
(720P): OSD expands horizontally. (Both edges of OSD may be hidden according to
circumstances.)
Your DL5500 is designed with cooling fans to provide air circulation for the optical engine
and a rotating component called the color wheel as part of the optical system. Under certain
viewing conditions, as in a quiet room during scenes with no audio or low volume level, the
sound generated by the fans or color wheel may be audible. This is a normal operating condition.
