Important Information

Precautions
Please read this manual carefully before using your plasma monitor and
keep the manual handy for future reference.
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO
NOT REMOVE COVER. NO USER-SERVICEABLE
PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE
PERSONNEL.
This symbol warns the user that uninsulated voltage
within the unit may have sufficient magnitude to cause
electric shock. Therefore, it is dangerous to make any
kind of contact with any part inside of this unit.
This symbol alerts the user that important literature
concerning the operation and maintenance of this unit
has been included.
Therefore, it should be read carefully in order to avoid
any problems.
WARNING
TO PREVENT FIRE OR SHOCK HAZARDS, DO NOT EXPOSE THIS
UNIT TO RAIN OR MOISTURE. ALSO DO NOT USE THIS UNIT'S
POLARIZED PLUG WITH AN EXTENSION CORD RECEPTACLE OR
OTHER OUTLETS, UNLESS THE PRONGS CAN BE FULLY
INSERTED. REFRAIN FROM OPENING THE CABINET AS THERE
ARE HIGH-VOLTAGE COMPONENTS INSIDE. REFER SERVICING
TO QUALIFIED SERVICE PERSONNEL.
Warnings and Safety Precaution
This plasma monitor is designed and manufactured to provide
long, trouble-free service. No maintenance other than cleaning
is required. Please see the section "Plasma monitor cleaning
procedure".
The plasma display panel consists of fine picture
elements (cells) with more than 99.99 percent active cells. There
may be some cells that do not produce light or remain lit.
For operating safety and to avoid damage to the unit, read
carefully and observe the following instructions.
To avoid shock and fire hazards:
1. Provide adequate space for ventilation to avoid internal heat build-
up. Do not cover rear vents or install the unit in a closed cabinet or
shelves.
If you install the unit in an enclosure, make sure there is adequate
space at the top of the unit to allow hot air to rise and escape. If the
monitor becomes too hot, the overheat protector will be activated and
the monitor will be turned off. If this happens, turn off the power to the
monitor and unplug the power cord. If the room where the monitor is
installed is particularly hot, move the monitor to a cooler location, and
wait for 60 minutes to cool the monitor. If the problem persists, contact
your dealer for service.
2. Do not use this unit's polarized plug with extension cords or outlets
unless the prongs can be completely inserted.
3. Do not expose the unit to water or moisture.
4. Avoid damage to the power cord, and do not attempt to modify the
power cord.
5. Unplug the power cord during electrical storms or if the unit will
not be used over a long period.
6. Do not open the cabinet which has potentially dangerous high voltage
components inside. If the unit is damaged in this way the warranty will
be void. Moreover, there is a serious risk of electric shock.
7. Do not attempt to service or repair the unit. The manufacturer is not
liable for any bodily harm or damage caused if unqualified persons
attempt service or open the back cover. Refer all service to authorized
Service Centers.
8. This equipment shall be connected to a MAIN outlet with a protective
earth-ground connection.
9. The outlet shall be installed near the equipment and shall be easily
accessible.
To avoid damage and prolong operating life:
1. Use only with 100-240V 50/60Hz AC power supply. Continued
operation at line voltages greater than 100-240 Volts AC will shorten
the life of the unit, and might even cause a fire hazard.
2. Handle the unit carefully when installing it and do not drop.
3. Set the unit away from heat, excessive dust, and direct sunlight.
4. Protect the inside of the unit from liquids and small metal objects. In
case of accident, unplug the power cord and have it serviced by an
authorized Service Center.
5. Do not hit or scratch the panel surface as this causes flaws on the surface
of the screen.
6. For correct installation and mounting it is strongly recommended to
use a trained, authorized dealer.
7. As is the case with any phosphor-based display (like a CRT monitor,
for example) light output will gradually decrease over the life of a Plasma
Display Panel.
8. To avoid sulfurization it is strongly recommended not to place the unit
in a dressing room in a public bath or hot spring bath.
9. Do not use in a moving vehicle, as the unit could drop or topple over
and cause injuries.
10. Do not place the unit on its side, upside-down or with the screen facing
up or down, to avoid combustion or electric shock.
Plasma monitor cleaning procedure:
1. Use a soft dry cloth to clean the front panel and bezel area. Never use
solvents such as alcohol or thinner to clean these surfaces.
2. Clean plasma ventilation areas with a vacuum cleaner with a soft brush
nozzle attachment.
3. To ensure proper ventilation, cleaning of the ventilation areas must be
carried out monthly. More frequent cleaning may be necessary
depending on the environment in which the plasma monitor is installed.
Recommendations to avoid or minimize image retention:
Like all phosphor-based display devices and all other gas plasma displays,
plasma monitors can be susceptible to image retention under certain
circumstances. Certain operating conditions, such as the continuous
display of a static image over a prolonged period of time, can result in
image retention if proper precautions are not taken. To protect your
investment in this plasma monitor, please adhere to the following
guidelines and recommendations for minimizing the occurrence of image
retention:
* Always enable and use your computer's screen saver function
during use with a computer input source.
* Display a moving image whenever possible.
* Change the position of the menu display from time to time.
* Always power down the monitor when you are finished using it.
If the plasma monitor is in long term use or continuous operation take the
following measures to reduce the likelihood of image retention:
* Lower the Brightness and Contrast levels as much as possible without
impairing image readability.
* Display an image with many colors and color gradations (i.e.
photographic or photo-realistic images).
* Create image content with minimal contrast between light and dark
areas, for example white characters on black backgrounds. Use
complementary or pastel color whenever possible.
* Avoid displaying images with few colors and distinct, sharply defined
borders between colors.
Plasma monitor driving sound
The panel of the Plasma monitor is composed of extremely fine pixels and
these pixels emit light according to received video signals. This principle
may cause you to hear a buzz or electrical hum coming from the Plasma
monitor. Also note that the rotation speed of the cooling fan motor increases
when the ambient temperature of the Plasma monitor becomes high. You
may hear the sound of the motor at that time.
Note:
The following items are not coverd by the warranty.
• Image retention
• Panel generated sound, examples: Fan motor noise, and electrical
circuit humming /glass panel buzzing.
Contact your dealer for other recommended procedures that will best
suit your particular application needs.
