Installation

Cautions

• Prevent internal heat build-up 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 monitor near equipment which
generates magnetism, such as a transformer or high
voltage power lines.
• Use the unit under an operating temperature of 0°C to
35°C (32°F to 95°F).
• When the unit is installed on the rack or on a shelf,
leave the space above and beneath the unit and
between the unit and other equipment.
• Use a fan to cool the unit if the spaces are small.

Precautions

On safety

• Operate the unit on 100 - 240 V AC only.
• The nameplate indicating operating voltage, power
consumption, etc. is located on the rear.
• 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.
• Unplug the unit from the wall outlet if it is not to be
used for several days or more.
• To disconnect the AC power cord, pull it out by
grasping the plug. Never pull the cord itself.
• The socket-outlet shall be installed near the equipment
and shall be easily accessible.

Handling the LCD screen

• Bright or dark points of lights (red, blue or green) may
appear on the LCD screen. This is not a malfunction.
The LCD screen is made with high-precision
technology and more than 99.99 % of the picture
element is intact. However, some of the picture
element may not appear or some of the picture element
may appear constantly.
• 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 monitor's screen. Do
not place a heavy object on the LCD monitor's screen.
This may cause the screen to lose uniformity.
• If the unit is used in a cold place, the horizontal lines
or a residual image may appear on the screen. This is
not a malfunction. When the monitor becomes warm,
the screen returns to normal.
• If a still picture is displayed for a long time, a residual
image may appear. The residual image will eventually
disappear.
• The screen and the cabinet become warm during
operation. This is not a malfunction.
