5. Allowable temperature and installation
environment
When installing the display in a narrow place (in a case embedded in a wall, etc.), leave gaps as shown in the gure below
between the display and the wall to prevent an increase in the temperature.
You may also implement suitable cooling measures.
100 mm
100 mm
30 mm
100 mm
100 mm
40°C (104°F) or less
The guaranteed ambient temperature for the display is 40°C (104°F).
When using it inside a case, take measures such as installing cooling fans in the case or air vents to keep the temperature
inside the case at a temperature of 40°C (104°F) or lower.
The display is equipped with temperature sensors and cooling fans. These fans turn on automatically when the inner
temperature is too high.
A warning is displayed in any environment that exceeds the guaranteed temperature, even when the cooling fans are
being used.
Using the display in an environment where a warning is displayed may cause a malfunction. In such a case, turn o the
main power supply.
In addition to automatic operation of the built-in cooling fans when the temperature exceeds the guaranteed temperature,
you can set the cooling fans to operate continuously under DISPLAY PROTECTION -> FAN CONTROL in the OSD menu.
When using the display with an option board, some of the cooling fans may turn on automatically to cool the option board
even when the display operates within the guaranteed temperature range.
When the display is installed inside a case or when it is used with the LCD surface covered with an acrylic sheet or other
protective sheets, check the inner temperature under DISPLAY PROTECTION -> HEAT STATUS in the OSD menu and then
congure the fan operation as required.

6. Wall mount brackets installation
(1) Use only mounting brackets that comply with the VESA standards.
(2) Install the display only after thoroughly checking the strength of the mounting surface.
(3) Use mounting brackets strong enough to support the display.
(4) Check the strength and other safety factors before installing the display.
(5) Refer to the mounting brackets manual for details on the mounting method and on how to guarantee the
installation safety.
(6) When using M6 screws, make screw holes of 8.5 mm or less in diameter.
When using M8 screws, make screw holes of 10 mm or less in diameter.

pull it in the direction of the arrow to remove it.
Remove the protective tape slowly. Otherwise, it may damage the display.
(5) Since the protective tape is very thin, it is possible to install the display in a multiple screens conguration without
removing it.
In this case, remove only the display cushions.

9. Multiple screens installation
(1) When installing the displays in a multiple screens conguration, turn the displays o and leave a gap of 1.0 mm
between each display.
Note that light from the back may pass through the gaps between the displays.
To prevent the light from passing through the gaps, install a plate that stops the light at the back of the displays.
This plate is not supplied by NEC.
Gap of 1 mm
Gap of 1 mm
(2) Consider the following when installing the display in a multiple screens conguration.
(a) Check that the wall to which the mounting brackets will be installed is perfectly at.
(b) Make sure that the mounting brackets used are strong enough to meet the installation requirements.
(c) Choose a structure in which load is not applied on the display top and left sides.
(d) Pay attention that the cable route does not interfere with other parts of the structure.
(e) Choose a conguration with which there is no risk that the displays bend after they have been installed.
English - 18
10. Pins, spacers and spacer sheets
Some display models are supplied with pins, spacers and spacer sheets.
With multiple screens conguration, installing the pins and the spacers makes it possible to secure a constant gap between
the displays.
However, the pins can be installed only on the models that have pin holes of 6 mm in diameter in their bottom and right
sides. The pins cannot be used with the other models. The pins and the spacers cannot be used with installation brackets
that allow the display to move, such as pantograph or sliding mechanisms.

Front side
(1) Spacers
The spacers supplied with the display can be installed in the screw holes on the top and left sides of the display.
They are useful to prevent the display from coming into contact on their weaker sides with other displays in multiple
screens conguration. Therefore, we recommend installing these spacers in this conguration.
However, the spacers cannot be used with installation brackets, such as pantograph or sliding mechanisms, that
allow the display to move back and forth or right and left.

(2) Pins
The pins supplied with the display can be installed in the screw holes on the top and left sides of the display.
They are useful to prevent the display from coming into contact on their weaker sides with other displays in multiple
screens conguration. Using these pins also facilitates alignment when xing the display to VESA wall mounting
brackets.
However, the spacers cannot be used with installation brackets, such as pantograph or sliding mechanisms, that
allow the display to move back and forth or right and left.

(3) Spacer sheets
Spacer sheets are useful to prevent the display from coming into contact on their weaker sides with other displays.
Remove the release paper from the double-sided tape on the back of the spacer sheet, and stick the spacer sheet
aligned with the edge at the back of the display.

Example: Spacer sheet installation with multiple screens conguration
* Caution: When using movable installation brackets
• If pins are installed to the display, the display cannot be moved.
• When spacers or spacer sheets are installed to the display, the spacers and the spacer sheets may contact or rub against
the display and cause image problems in the case the display is allowed to move.
• Do not install the pins, spacers or spacer sheets when using a movable bracket or an adjustable stand that allows the
display to move.
• Example of movable installation brackets are such as pantograph mechanisms, slide mechanisms.

13. When repacking and sending the product
Some of the display models have protective tape stuck on their upper side to protect them from shocks during installation.
With these models, always stick the display cushions back in place before sending the display.
Sending the display without the cushions may cause malfunctions due to vibrations during transportation.
If the cushions have been lost, fold inward the corners of the front ap of the box following the lines to pack the display.
The packing method is as follows.
