Operating Range for the Remote
Control
Point the top of the remote control toward the LCD monitor’s
remote sensor during button operation.
Use the remote control within a distance of about 7 m (23 ft.)
from the front of the LCD monitor’s remote control sensor or
at a horizontal and vertical angle of within 30° within a
distance of about 3.5 m (10 ft.)
Caution:Important, the remote
control system may
not function when
direct sunlight or strong
illumination strikes the remote control
sensor of the LCD monitor, or when there is
an object in the path.
Handling the remote control
• Do not subject to strong shock.
• Do not allow water or other liquid to splash the remote
control. If the remote control gets wet, wipe it dry
immediately.
• Avoid exposure to heat and steam.
• Other than to install the batteries, do not open the remote control.

1. Determine the installation location
CAUTION:Installing your LCD display must be done by a
qualified technician. Contact your dealer for
more information.
CAUTION:
MOVING OR INSTALLING THE LCD MONITOR
MUST BE DONE BY TWO OR MORE PEOPLE.
Failure to follow this caution may result in injury if
the LCD monitor falls.
CAUTION: Do not mount or operate the display upside
down, face up, or face down.
CAUTION: This LCD has a temperature sensor and cooling
fan. If the LCD becomes too hot, the cooling fan
will turn on automatically. If the LCD becomes
overheated while the cooling fan is running, a
“Caution” warning will appear. If the “Caution”
warning appears, discontinue use and allow the
unit to cool. Using the cooling fan will reduce the
likelihood of early circuit failure and may help
reduce image degradation and “Image
Persistance”.
If the LCD is used in an enclosed area or if the
LCD panel is covered with a protective screen,
please check the inside temperature of the
monitor by using the “HEAT STATUS” control in
the OSD (see page 21). If the temperature is
higher than the normal operating temperature,
please turn the cooling fan to ON within the
SCREEN SAVER menu within the OSD (see
page 21).
IMPORTANT: Lay the protective sheet, which was wrapped
around the LCD monitor when it was
packaged, beneath the LCD monitor so as
not to scratch the panel.
2. Install the remote control batteries
The remote control is powered by two 1.5V AAA batteries.
To install or replace batteries: NEC recommends the following battery use:
• Place “AAA” size batteries matching the (+) and (-) signs
on each battery to the (+) and (-) signs of the battery
compartment.
• Do not mix battery brands.
• Do not combine new and old batteries. This can shorten battery life or cause liquid leakage of batteries.
• Remove dead batteries immediately to prevent battery
acid from leaking into the battery compartment.
• Do not touch exposed battery acid as it may injure skin.
NOTE: Remove the batteries if you do not intend to use the
remote control for a long period of time.
3. Connect external equipment (See pages 14-15)
• To protect the external equipment; turn off the main power before making connections.
• Refer to your equipment user manual for further information.
4. Connect the supplied power cord
• The equipment should be installed close to an easilyaccessible power outlet.
• Fully insert the prongs into the power outlet socket. A loose connection may cause image degradation.
NOTE: Please refer to the “Safety Precautions and
Maintenance” section of this manual for proper
selection of AC power cord.
Setup
A. Press and slide to open the cover.
B. Align the batteries according to the (+) and (–) indications inside the case.
C. Replace the cover.
CAUTION: Incorrect usage of batteries can result in leaks
or bursting.

5. Switch on the power of all the attachedexternal equipment
When connected with a computer, switch on the power of
the computer first.
6. Operate the attached externalequipment
Display the signal from the desired input source.
7. Adjust the sound
Make volume adjustments when required.
8. Adjust the screen (See pages 19 and 20)
Make adjustments to the screen display position when
necessary.
9. Adjust the image (See page 19)
Make adjustments such as brightness or contrast when
required.
10. Recommended Adjustments
To reduce the risk of the “Image Persistence”, please adjust
the following items based on the application being used:
“POWER SAVE”, “SCREEN SAVER”  (See page 21),
“SIDE BORDER COLOR” (See page 22), “DATE AND TIME”,
“SCHEDULE” (See page 20).
11. To prevent the main power switch from being changed
To prevent use of the main power switch, please attach the
main switch cover, which is enclosed as an accessory.

Connections
NOTE:Do not connect/disconnect cables when turning on the monitor or other ex\
ternal equipment as this may result in a
loss of the monitor image.
NOTE: Use an audio cable without a built-in resistor. Using an audio cable with a built-in resistor turns down the sound.
Before making connections:
* First, turn off the power of all attached equipment and make connections.
* Refer to the user manual included with each separate piece of equipment.\

Using Power Management
The LCD monitor follows the VESA approved DPM Power
Management function.
The power management function is an energy saving
function that automatically reduces the power consumption
of the display when the keyboard or the mouse has not been
used for a fixed period.
The power management feature on your new display has
been set to the “ON” mode. This allows your display to enter
a Power Saving Mode when no signal is applied. This could
potentially increase the life and decrease the power
consumption of the display.
NOTE:Depending on the PC and video card used, this
function may not operate.
Selecting a video source
To view a video source:
Use the input button to set [HDMI], [VIDEO1], [VIDEO2] or
[S-VIDEO].
Use the COLOR SYSTEM menu to set [AUTO], [PAL],
[NTSC], [PAL60], [4.43NTSC], [SECAM], according to your
video format.
