Precaution
On Safety
• Operate the unit only with a power source as specified
in the “Specifications” section.
• A nameplate indicating operating voltage, etc., is
located on the rear panel.
• Should any solid object or liquid fall into the cabinet,
unplug the unit and have it checked by qualified
personnel before operating it any further.
• Do not drop or place heavy objects on the power cord.
If the power cord is damaged, turn off the power
immediately. It is dangerous to use the unit with a
damaged power cord.
• Unplug the unit from the wall outlet if it is not to be
used for several days or more.
• Disconnect the power cord from the AC outlet by
grasping the plug, not by pulling the cord.
• The socket-outlet shall be installed near the equipment
and shall be easily accessible.
On Installation
• The LCD panel can be used in portrait or landscape
orientation. Make the appropriate settings for display
orientation on your computer.
• Prevent internal heat build-up by allowing adequate
air circulation.
Do not place the unit on surfaces (rugs, blankets, etc.)
or near materials (curtains, draperies) that may block
the ventilation holes.
• Do not install the unit near heat sources such as
radiators or air ducts, or in a place subject to direct
sunlight, excessive dust, mechanical vibration or
shock.
• Do not place the unit near equipment which generates
magnetism, such as a transformer or high voltage
power lines.
About the LCD Panel
• The LCD panel fitted to this unit is manufactured with
high precision technology, giving a functioning pixel
ratio of at least 99.99%. Thus a very small proportion
of pixels may be “stuck”, either always off (black),
always on (red, green, or blue), or flashing. In
addition, over a long period of use, because of the
physical characteristics of the liquid crystal display,
such “stuck” pixels may appear spontaneously. This is
not a malfunction.
• Do not leave the LCD screen facing the sun as it can
damage the LCD screen. Take care when you place the
unit by a window.
• Do not push or scratch the LCD screen. Do not place
a heavy object on the LCD screen. This may cause the
screen to lose uniformity.
• If the unit is used in a cold place, a residual image may
appear on the screen. This is not a malfunction. When
the unit becomes warm, the screen returns to normal.
• The screen and the cabinet become warm during
operation. This is not a malfunction.
Even if it is used properly, the unit may cause harmful
interference to radio or television reception. Try the
following measures to correct it.
• Increase the distance between the unit and the radio/
TV.
• Connect the unit to a different outlet from the one to
which the radio/TV is connected.
Protective Filter
The LCD panel comes with an anti-reflection-coated
protective filter. The surface is very delicate. Do not rub
or hit with hard objects.
On Burn-in
Permanent burn-in may occur if still images are
displayed in the same position on the LCD panel
continuously, or repeatedly over extended periods.
Images that may cause burn-in
• Images that remain static for a long time
• Character or message displays that indicate settings or
operating state
To reduce the risk of burn-in
• Turn on the screensaver function
Turn on the screensaver or enable the standby mode to
avoid permanent burn-in of an image displayed for an
extended period on the LCD panel.
• Turn off the power when not in use
Turn off the power if the unit is not to be used for an
extended period of time.
