Warnings and Safety Precautions
The monitor is designed and manufactured to provide long, trouble-
free service. No maintenance other than cleaning is required. Use a
soft dry cloth to clean the panel. Never use solvents such as alcohol
or thinner to clean the panel surface.
The display panel consists of fine picture elements (cells). Although
the display panels are produced 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 in a closed cabinet or
shelves.
The unit is equipped with cooling fans. If you install the unit in
an enclosure, be 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 un-plug the power cord. If the
room where the monitor is installed is particularly hot, move the
monitor to a cooler location, and wait for the monitor to cool for
60 minutes.
If the problem persists, contact your dealer for service.
2. Do not use the power cord plug with extension cords or outlets
unless all prongs can be completely inserted.
3. Do not expose unit to water or moisture.
4. Avoid damage to the power cord, and do not attempt to modify
the power cord.
5. Unplug unit during electrical storms or if unit will not be used
over a long period.
6. Do not open the unit which has potentially dangerous high
voltage components inside. If the unit is damaged from opening
the cabinet the warranty will be void. Moreover, there is a serious
risk of electric shock.
7. Do not attempt to service or repair the unit. Tmm 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.
To avoid damage and prolong operating life:
1. Use only with 120V 50/60Hz AC power supply. Continued
operation at line voltages greater than 120 Volts AC will shorten
the life of the unit, and might cause a fire hazard.
2. Handle the unit carefully when installing it.
3. Locate set 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 unit 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. Like all phosphor-based display devices, monitors can be
susceptible to uneven phosphor aging under certain
circumstances. Certain operating conditions, such as the
continuous display of a static image over a prolonged period of
time, can result in uneven phosphor aging if proper precautions
are not taken. To protect your investment in this monitor, please
adhere to the following guidelines and recommendations for
minimizing the occurrence of uneven phosphor aging:
• Always enable and use your computer’s screen saver function
during use with a computer input source.
• Display a moving image whenever possible.
• Always power down the monitor when you are finished using it.
• If viewing with a 4/3 aspect ratio for long periods of time, set side
gray level at 3 or 4.
If the monitor is in long term use or continuous operation take the following
measures to reduce the likelihood of uneven phosphor aging:
• 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.
