Operating Precautions
The LCD panel and backlight have life expectancy. Due to the basic characteristics of the LCD panel, an afterimage or uneven display
may occur. It is recommended that you change images occasionally, activate the power saving function, or often turn off the power to
reduce the load on the LCD panel. Continuous operations of the LCD panel may accelerate the deterioration.
Caution for use of the product for many hours
In the case that you use the monitor for many hours, we recommend that you set “No Sync Action” in “Sync Function” to “Power Save” in
Main Menu. This will reduce power consumption and relieve strain on the monitor. To reduce damage to the LCD panel, using the LCD
Saver function is recommended.
Caution for use of the product in the high temperature
Do not use the product in places of high temperature; otherwise, parts of this product or the LCD panel may be damaged. This product is
equipped with a temperature sensor to give warning if the temperature becomes too high. If the temperature exceeds the range of normal
use, “Temp. Over” is displayed, and the power is turned off automatically if the temperature becomes any higher. In this case, move the
product to a place of low temperature to let it cool down.
Maintenance
Unplug this product from the wall outlet before cleaning.
Screen
Cabinet
To avoid the deterioration or damages of the cabinet such as its
paint’s peeling away, be careful about the following:
● Do not wipe the cabinet using solvent such as alcohol, thinner,
or benzine.
● Do not expose the cabinet to any volatile substance such as
insecticides.
To avoid irreparable change in appearance of the screen such
as uneven color, discoloration, scratches, be careful about the
following:
● Do not paste or stick anything using any glues or adhesive
tapes.
● Do not write anything on the screen.
● Do not strike the screen with a hard object.
● Avoid condensation on the screen.
● Do not allow any rubber or plastic in contact for a long time.
● Do not wipe the cabinet forcefully.
● Do not wipe the screen with any liquid such as water. In
addition, wiping the screen with water-diluted neutral
detergent or solvent such as alcohol, thinner, or benzine may
affect the anti-reflection treatment of the screen.
● Do not wipe the screen forcefully.
Wipe stains off the cabinet with a soft cloth. If the cabinet gets
heavily stained, wipe it with a soft cloth soaked in water-diluted
neutral detergent and wrung well, then wipe with a soft dry cloth.

heavily stained, wipe it with a soft cloth soaked in water-diluted
neutral detergent and wrung well, then wipe with a soft dry cloth.
Use a vacuum cleaner to get rid of the dust around the intakes (all
the openings). If a vacuum cleaner is not available, use a cloth and
wipe it off. Leaving the dust around the intakes may prevent proper
temperature control and cause damage to the product.

5 Use no less than two commercially available screws (no less than
four screws on both sides) for the screw holes (10 – φ8) on the
stand bottom plate, to anchor the monitor. (Use screws having
enough holding strength and resistance against external force of
expected vibrations.)
Stand support
2 Temporarily set the stand screws to screw holes “3” on the right
and left sides of the stand support.
● Tighten the temporarily set stand screws so that they protrude
from the screw holes by about 4 mm.

● To install the monitor on a wall
You can install the monitor on a wall by changing how the stand
bottom plate is attached.
Caution
● Consult authorized service personnel for electrical work. Using
power cords damaged during installation (i.e., exposed or severed
wiring) may result in fire or electric shock.
● Conduct the work with adequate working space. Damage or bodily
injury may result from working under unsuitable conditions.
● Avoid mounting this unit in areas where there is electrical wiring or
water pipes, as fire or electric shock may result.
Installation Only for Authorized Service Personnel
Consult authorized service personnel for the installation of this
unit.
Installation instructions must be followed precisely in order to
prevent accidents.
We are selling this product with the understanding that it will be
assembled and installed by properly trained and qualified service
personnel.
1 Lay the monitor on a cloth with the LCD panel facing down to
prevent the LCD panel from being damaged. Loosen the stand
screws on the stand support and remove the bottom plate.
About Accidents/Damages
We are not liable for any damage caused by faulty assembly, faulty
wall mounting, insecure wall mounting, misuse, alterations, or
natural disasters.
Bottom plate
● Please be aware that screw holes and anchor bolts will remain
in the wall surface if the monitor is removed after having been
mounted to the wall.
Long-term use of the LCD display monitor may result in
discoloration of the wall surface due to heat/air emitted by the
display.
Stand support
2 Temporarily set the stand screws in screw holes “2” and “4” on the
right and left sides of the stand support.
Danger
● Tighten the temporarily set stand screws so that they protrude
from the screw holes by about 4 mm.
● Consult authorized service personnel for the installation and
attachment of this unit to the wall. Do not attempt to mount the
unit by yourself.
Stand screws “2” and “4”
Improper assembly or installation may cause the unit to fall when
it is mounted, which may result in fatal accidents.
To prevent this happening, check the strength of the materials
in the mounting surface. Check the material strength again after
mounting as well.
Warning
● Using a monitor other than this product may result in damage or
bodily injury due to the LCD display monitor toppling over.
● Assemble all screws securely. Failure to do so may result in the LCD
monitor and stand falling down, potentially causing damage or
bodily injury.
3 Tighten commercially available screws in the 6 holes shown in the
figure below to install the monitor on the wall.
● This unit does not come with anchor bolts for securing it to walls,
etc. Be sure you have materials on hand as appropriate for the
mounting location.
● The monitor should be mounted to a wall that can adequately
hold the total weight of the monitor and stand over a long
period of time and which can adequately withstand earthquakes,
conceivable vibrations, and other external forces.
● Mounting On Wooden Walls
The weight of the unit should be borne by the wall posts or studs,
and these should be reinforced if insufficiently strong. Do not
install the Wall Mounting Unit on walls made of plasterboard or
thin plywood. Use the commercially sold screws best suited for the
wall structure and material.
4 Hook the temporarily set screws on the stand support in right
and left recesses “A” and “B” on the bottom plate, tighten the two
stand screws in right and left screw holes “D” and finally retighten
the temporarily set screws to lock the stand support and bottom
plate.
● Mounting On Concrete Walls
Recesses “A” and “B”
Use commercially sold wall anchors capable of supporting the
weight of the LCD monitor.
● Do not install the Wall Mounting Unit near the blower or air inlet of
an air conditioner.
● Do not install the Wall Mounting Unit in a location subject to
frequent vibration, impact or other external forces.
● Do not install the unit in a location where people may hang on it or
lean against it.
● Do not block the ventilation holes.
● Do not install the monitor on a non-vertical wall.
