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

Allow adequate air circulation to prevent internal heat

build-up.
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 in a location near heat sources

such as radiators or air ducts, or in a place subject to
direct sunlight, excessive dust, mechanical vibration or
shock.

Handling the Screen

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. These
problems are 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, 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.
 The screen and the cabinet become warm during
operation. This is not a malfunction.

On Burn-in

For LCD panel, permanent burn-in may occur if still
images are displayed in the same position on the screen
continuously, or repeatedly over extended periods.
Images that may cause burn-in
Masked images with aspect ratios other than 16:10

(LMD-A240)
 Masked images with aspect ratios other than 16:9
(LMD-A220/A180)
Color bars or images that remain static for a long time

Character or message displays that indicate settings or

the operating state
 On-screen displays such as center markers or area
markers
To reduce the risk of burn-in
 Turn off the character and marker displays
Press the MENU button to turn off the character
displays. To turn off the character or marker displays
of the connected equipment, operate the connected
equipment accordingly. For details, refer to the
operation manual of the connected equipment.
 Turn off the power when not in use
Turn off the power if the monitor is not to be used for
a prolonged period of time.
Screen saver
This product has a built-in screen saver function to
reduce burn-in. When [Screen Saver] is set to [On] in
the [System Setting], the screen brightness will decrease
if an almost still image is displayed for more than 10
minutes.

On Image Smearing

Due to an LCD's panel structure and characteristics of
materials in its design, continuously displaying signals
or/and image patterns may cause image smearing or/and
flicker on the monitor. If a problem like this occurs,
display a white screen display or a video on the monitor
for a while.
