Cautions for Rack-Mount.
1) Elevated Operating Ambient - If installed in a
closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment
may be greater than room ambient. Therefore,
consideration should be given to installing the
equipment in an environment compatible with the
maximum ambient temperature (Tma) specified
by the manufacturer.
2) Reduced Air Flow - Installation of the
equipment in a rack should be such that the
amount of air flow required for safe operation of
the equipment is not compromised.
3) Mechanical Loading - Mounting of the
equipment in the rack should be such that a
hazardous condition is not achieved due to uneven
mechanical loading.
4) Circuit Overloading - Consideration should be
given to the connection of the equipment to the
supply circuit and the effect that overloading of
the circuits might have on overcurrent protection
and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used
when addressing this concern.
5) Reliable Earthing - Reliable earthing of
rack-mounted equipment should be maintained.
Particular attention should be given to supply
connections other than direct connections to the
branch circuit (e.g. use of power strips).

v
Precautions Upon Use
In order to use the monitor safely, read through this manual and pay attention to the following
points in particular.
1. Do not use any power supply other than the specified one (AC/DC).
2. Do not give a shock to the monitor.
Be very careful to keep the monitor from shocks because glass is used inside the LCD.
3. Do not use or store the monitor in the following places.
Place where the ambient temperature is out of spec
When installing the monitor on a monitor shelf, switcher table, rack, etc., make sure in advance
that the temperature of the installation location is within the specified range.
In the case of an outdoor setup, even if the ambient temperature is within the specified range,
the inside of the monitor may be heated by direct sunlight. Therefore, keep radiation in mind.
(Avoid direct sunlight.)
Never block the air outlet at the rear of the monitor and the air inlet at the side. Make sure in
particular that a blackout curtain or the like does not block the air outlet.
Place exposed to rain, snow or high humidity
Use of the monitor in such a place will cause electric leakage or failure.
4. Please avoid direct sunlight on the screen.
Exposure of the LCD screen to direct sunlight for a long time will degrade the film. Therefore be
careful of direct sunlight when using the monitor outdoors.
5. Caution for the panel surface
Be careful not to touch the LCD panel front surface with bare hands, unless necessary. When
wiping the dust off the surface, use soft, dry cloth and take care not to rub the surface strongly.
Do not use thinner or benzene.
6. Do not touch liquid crystal leaked from the monitor's display surface.
If the monitor's display surface is accidentally broken and the liquid crystal leaks, be careful
never to put the liquid in your mouth, inhale it and allow it on your skin. If the liquid gets into
your eye or mouth, immediately rinse it with water and get medical attention.
If the liquid contacts your skin or clothes, immediately wipe it off using alcohol or the like and
wash the stained spot with soap and water. Do not leave the liquid intact, because otherwise
your skin or clothes may be affected.
7. Caution when used for a long continuous display
If the LCD panel is used for a long continuous display of fixed bright images, still images, etc. or
continuously used under hot and humid environment, after-images, lower luminance, seizure,
stains, streaks, etc., may occur due to the structure of the LCD panel.
Please avoid a long continuous display of videos with especially bright still images, white displays
of computer windows, videos that are smaller than the display area because of the aspect change,
etc. Also avoid continuously using it in a closed room that can be hot and humid or near outlets of
air conditioning equipment.
A long continuous use with such videos and environment can cause the LCD panel to age at a
faster rate.
In order to prevent the aging phenomenon, we recommend to avoid a long continuous display of
fixed bright images or still images and lower the brightness, as well as to turn off the power of the
main unit when it is not used.
(After-images may be gradually resolved by changing the screen display.)

vi
8. Avoid operation at low temperatures.
The response speed of the liquid crystal decreases as the temperature decreases. Therefore, it is
recommended to use the monitor at room temperature.
9. Caution for condensing.
When the monitor is used in the condition where temperature abruptly changes, the surface of
outside and the inside of monitor are possible to get condensed.
And if it is used leaving condensed, it can cause deterioration of quality and trouble.
If the device is condensed, please do not turn on the power until waterdrop is disappeared
completely.
10.Avoid operation or storage in a place exposed to corrosive gas.
Operation or storage in a place where any corrosive gas such as sulfur dioxide, hydrogen sulfide,
chlorine or ammonia is generated may lead to a significant reduction in the monitor service life.
It may also cause failure or electric leakage.
Also avoid using the monitor in a location exposed to high salty wind.
11.Do not use this monitor for such applications as space appliance, nuclear control system as
any medical equipment involving human life.
12.Considerations when storing the monitor in a hard carrying case.
The LCD panel used for this monitor has a very delicate structure that is composed of multiple
layers of expensive films. Therefore, the following considerations must be taken into account
when storing the monitor in a hard case.
・If the monitor that has been stored at low temperature for a long time is suddenly exposed to
high temperature environment, dew condensation may occur. When you store the monitor in
the case for a long time, make sure to store at a temperature near room temperature and
avoid a sudden temperature change when taking out the monitor from the case.
・If you are planning to store the monitor in the case for a long time, make sure to replace silica
gels, etc. in a regular basis and store the monitor at proper humidity as the humidity in the
case can cause corrosion.
・If the monitor is stored in the case with water droplets or condensation for a long time, the
humidity stays in the case and can cause corrosion. Make sure to allow the monitor to dry well
before storing in the case.
Quality of LCD panel
Note that because the LCD panel mounted on the monitor is manufactured through the use of
high-precision technology, 99.99% or more of the pixels are effective, but 0.01% or less of them
may be lacking in brightness or lit up constantly.
Internal fan
The internal fan does not run constantly but automatically starts running when the internal
temperature of the monitor rises. When the environmental temperature is low, the internal fan
may not be running, which indicates no fault condition.
At power-on, the fan rotates for a moment for checking its own performance.
In the case of outdoor use, even if the ambient temperature is low, the fan may start running
when the internal temperature of the monitor rises.
Suppose that the fan does not operate properly at power-on or at high temperatures. In such

vii
case, the message "FAN ERROR!" will appear at the top of the screen.
The brightness of the backlight may be reduced in order to keep the internal temperature of the
motor from rising.
If the message "FAN ERROR!" is displayed, contact your dealer or Panasonic service desk.
