HOW TO SET UP YOUR NEW HITACHI PLASMA TELEVISION
VIEWING
The major benefit of the HiTACHi Plasma 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 TV and about 8 to 18 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 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
NO, Items Notes
1 Arching sound from A buzzing sound might be heard when the plasma display monitor is turned on in a very quiet
plasma display monitor's room. This is due to the plasma panel drive circuit when it is functioning, This arching sound
panel, is normal and it is not a malfunction.
2 Interference for infrared Some infrared rays are emitted from the plasma display monitor's panel that might affect other
equipment, infrared controlling equipment.
3 Bright and dark spots High-precision technology is used to manufacture the plasma display panel; But in some
cases, there are minor defects in some parts of the screen. Points that do not light, points
with brightness different from that of the periphery, points with color different from that of the
periphery, etc. Some pixels will always be on or always off. Please note that this is not a
malfunction.
4 Picture Image (Spectrum'j When receving still picture signals, (e.g. channel number indication or clock indication) for a
while, you can see imageqike when the picture varied. This is not a defect.
5 Display panel surface The plasma display panel is lighting the phosphors by the discharge of internal radiation. In
temperature is too high some cases, this may cause the temperature of the panel surface to increase. Please note
that this is not a malfunction. The Plasma TV surface temperature is higher than a
Cathode-ray-tube.
6 Plasma Surface The plasma panel is made from glass. Heavy shock on the front panel might damage it.
7 Transportation When the PDP monitor is transported horizontally, the glass panel has the possibility of being
broken or increasing the picture defects. At the time of transportation, horizontal style is
prohibited. More-over, please treat the plasma panel with great care because of a precision
apparatus. Please instruct transporters so that it should be put into the packing box at the time
of shipment.(There is a possibility that breakage of the panel or defects will increase.)
Rough transportation might cause damage to the panel and pixel failure.
8 Image retention The plasma monitor illuminates phosphor to display images. The phosphor has a finite
illumination life. After extended periods of illumination, the brightness of the phosphor will be
degraded to such extent that stationary images would bumqn that part of the screen as
grayed-out images. For 50" only, brightness will decrease automatically dudng still and slightly
moving pictures. This is not a failure. This is a special feature to avoid image retention.
Tips to prevent such image retention are:
- Do not display images having sharp brightness differences or hi-contrast images, such as
monochrome characters and graphic patterns, for long.
- Do not leave stationary images appearing for long, but try to refresh them at appropriate
intervals of time, or try to move them using screen saver function.
- Turn down the contrast and brightness controls.
9 Luminosity and contrast PDP television has luminosity and low contrast compared with CRT television.
10 Granular spots When a screen is seen at point-blank range, a random fine grain may be visible to a dark part.
11 Disturbance to video If an apparatus (VCR, etc.) antenna line is arranged near the monitor, the image may shake,
apparatus or disturbance may be received.
12 Lip Sync There is some time lag betweeen the picture and the sound. You can see lip motion that is
delayed compared to the sound.
13 About the use Electric discharge/luminescence characteristic of the PDP panel also changes with peripheral
environment of PDP temperature. Moreover, since there is also high power consumption value, a specified
television (temperature) temperature environment is required.
14 Caution on prolonged Storing the plasma television for a period of more than 2 to 3 months without use might cause
storage an unstable picture when the set is turned on.
15 Operating Operating altitude: 800 to 1114hPa (6194ft to -2484ft). Operating temperature: 41°F to 95°F.
16 Storage Storage Altitude: 300 to 1114hPa (15510f1 to -2484ft). Storage temperature: 5°F to 140°F.
17 Power ON or OFF Frequent use of the Power ON or OFF might trigger the power protection circuit. IftheTV
does not turn ON, please wait a little before turning ON again.
