Precautions for using batteries

If batteries are used improperly, the liquid could leak out, causing a fire, injury, etc. or dirtying the vicinity.
Take notice of the following:

• Do not mix old and new batteries.

• Do not mix different types of battery as different types may have different characteristics.

• Place the batteries according to the ª and · markings indicated on the battery compartment.

• When installing the batteries, insert the · end first to avoid a short circuit.

• Use only the specified batteries.

• When you are not using the remote control for a long time, remove the batteries.

• When the batteries have reached the end of their life, replace them with new ones immediately. Otherwise, the liquid may leak
out, or malfunction may be caused by the leaked liquid. If the leaked liquid contacts your skin, wipe off the liquid with a soft
cloth. If the affected skin is left as is, you may get a rough skin.

• Do not throw the batteries into fire or try recharging them.

• The service life of batteries is six months to one year for normal use. The supplied batteries are only for checking the operation

Installation

Precautions

• When mounting the Monitor vertically, consult your dealer. (See also page 13).

• When installing the Monitor, be sure to use a dedicated Stand Unit, Wall Mounting Unit, or Monitor Hanger Unit, depending
on a particular case. Ask your dealer for installation.

• When installing the Monitor, refer also to the user manual for each option to use. Do not tilt the Monitor rightward, leftward,
or backward.

• Route the power cord and connection cables along wall or floor corners to avoid walking on them.

• For good heat dissipation, try to leave the following distances of space (minimum) around the Monitor.

• The ambient temperature of the installation place should be within the range of 0˚C to 40˚C.

• When installing the Monitor in a place, such as near the ceiling, the remote control may not work correctly because of possible
effects from the surroundings. If this happens, use the remote control as a wired remote control or move the Monitor where it
is free from these effects.

When installing the Monitor on a stand

When mounting the Monitor on the wall

Notes:

• Do not allow the same image (pattern) to be continuously displayed on the screen for a long time; otherwise, the area on the
screen corresponding to the image may vary in brightness, leaving an afterimage on the screen. To reduce the afterimage, you
can use the Refresh function (see page 28).

• The Monitor is manufactured using very high-precision technology, allowing for more than 99.99% active pixels, however, be
aware that only a slight number of pixels may be deficient or lit at all times.

• Do not install the Monitor in such a way that the Monitor and other AV equipment affect each other adversely. (For example,
if a disturbed image or noise due to electromagnetic interference occurs, or if the infrared remote control malfunctions, change
the installation place.)

Changing the Aspect Ratio

Precautions for using the screen mode switching function

• This Monitor features a screen mode switching (aspect ratio
change) function. If you select a mode different in aspect
ratio from software such as TV programs, the picture may
look different from original picture. Be aware of this point
when you are selecting a screen mode.

• If you select a wide screen mode while viewing
conventional video programs of the aspect ratio 4:3, some
portions (edges) of the original picture will be cut off, or
deformed. To enjoy the original picture as it is, select
“REGULAR” while viewing such programs.

• If you place the Monitor in a tea room, hotel, etc. for
business purposes or public viewing and modify the picture
by using the screen mode switching (aspect ratio change)
function, this could violate the copyright protected by the
copyright law, which requires your special attention.

• If you make the screen very bright and watch programs
selecting “REGULAR” for a long period of time, the
Monitor screen may happen to be burned in. If this occurs,
watching programs using a wide screen mode for a while
will reduce the burn-in gradually.

With this Monitor, you can select among three types of wide
screens (FULL, ZOOM, and PANORAMIC) in addition to the
REGULAR screen of conventional 4:3 aspect ratio.

Press ASPECT to select the screen size

Each time you press the button, the screen size changes as
follows:

REGULAR: Displays at conventional 4:3 aspect ratio.

FULL: REGULAR size display is enlarged

horizontally.

ZOOM: REGULAR size display is enlarged

vertically and horizontally at the same ratio.

PANORAMIC: REGULAR size display is enlarged

horizontally to the extent that the picture
does not look abnormally.

Notes:

• When one of the following signals is being input, you
cannot select the aspect ratio you want.

■ 1080i, 1035i or 720p signal through the COMPONENT/RGB

B input terminals

You can only select FULL.

■ When any signal other than RGB15K-60 and RGB15K-50

through the RGB A or COMPONENT/RGB B input terminals

You can select only REGULAR and FULL.

• The aspect ratio can also be changed on the Function
Selection Menu (page 21).

Adjusting the Screen Size and Position

The screen size and position can be adjusted.
Adjusted settings can be stored for each signal type; therefore,
when the same signal comes in, the stored settings are
recalled.

• When adjusting the size, the size cannot be adjusted
proportionally, but can be enlarged rightward (or
downward) only and reduced leftward (or upward) only.
Therefore, it is necessary to adjust both the size and position
alternately to adjust to the appropriate size.

If “TEMP. OVER” lights or flashes at the right bottom of the

screen, check the following before consulting the dealer
where you purchased the Monitor.

“TEMP. OVER” appears to warn you of the internal heat

buildup, which is usually caused by accumulated dust
around the intakes or by improper installation. If the cause
of the internal heat buildup is eliminated, this indication
disappears and the screen recovers the brightness.

location of the Monitor. In this case, consult your
dealer immediately to solve this improper
installation and to improve the circumstances around
the Monitor.
