Introduction to the NEC MultiSync LCD1525V E - 1
Introduction to the NEC MultiSync LCD1525V
Congratulations on your purchase of the NEC MultiSync LCD1525V
true colour monitor!
Wider Compatibility
Because the MultiSync LCD monitor is analog through and through, it
does not require special analog to digital display or interface cards but
can accept RGB input directly.
Reduced Footprint
Provides the ideal solution for environments requiring superior image
quality but with size and weight limitations. The monitor’s small foot-
print and low weight allow it to be moved or transported easily from one
location to another.
Colour Control System
Allows you to adjust the colours on your screen and customize the colour
accuracy of your monitor to a variety of standards.
OSM (On-Screen Manager) Controls
Allow you to quickly and easily adjust all elements of your screen image
via simple to use on-screen menus.
ErgoDesign Features
Enhance human ergonomics to improve the working environment,
protect the health of the user and save money. Examples include OSM
controls for quick and easy image adjustments, tilt/swivel base for
preferred angle of vision, small footprint and compliance with MPRII
guidelines for lower emissions.
Plug and Play
The Microsoft®solution with the Windows®operating system facilitates
setup and installation by allowing the monitor to send its capabilities (such
as screen size and resolutions supported) directly to your computer, auto-
matically optimizing display performance.
LCD1525E.PM5 99/06/09, 14:33Page 13 PageMaker5.0J

IPM (Intelligent Power Manager) System
Provides innovative power-saving methods that allow the monitor to shift
to a lower power consumption level when on but not in use, saving two-
thirds of your monitor energy costs, reducing emissions and lowering the
air conditioning costs of the workplace.
Multiple Frequency Technology
Automatically adjusts monitor to the display card’s scanning frequency,
thus displaying the resolution required.
FullScan Capability
Allows you to use the entire screen area in most resolutions, significantly
expanding image size.

Safety Precautions and Maintenance
For optimum performance, please note the following when setting up and
using the MultiSync LCD colour monitor:
• DO NOT OPEN THE MONITOR.There are no user serviceable
parts inside and opening or removing covers may expose you to
dangerous shock hazards or other risks. Refer all servicing to
qualified service personnel.
• Allow adequate ventilation around the monitor so that heat can
properly dissipate. Do not block ventilated openings or place
the monitor near a radiator or other heat sources. Do not put
anything on top of monitor.
• Do not spill any liquids into the cabinet or use your monitor
near water.
• Do not insert objects of any kind into the cabinet slots, as they
may touch dangerous voltage points, which can be harmful or
fatal or may cause electric shock, fire or equipment failure.
• Do not place any heavy objects on the power cord. Damage to
the cord may cause shock or fire.
• Do not place this product on a sloping or unstable cart, stand or
table, as the monitor may fall, causing serious damage to the
monitor.
• The power cable connector is the primary means of detaching
the system from the power supply. The monitor should be
installed close to a power outlet that is easily accessible.
• When operating the MultiSync LCD monitor with its AC220-
240V worldwide power supply, use a power supply cord that
matches the power supply voltage of theAC power outlet being
used. The power supply cord you use must have been approved
by and comply with the safety standards of your country.
• Use supplied AC Adapter.
• No Object shall be placed onAC Adapter.
E - 4 Recommended Use
LCD1525E.PM5 99/06/09, 14:33Page 16 PageMaker5.0J

• AC Adapter shall not be used outdoors.
• Handle with care when transporting. Save packaging for trans-
porting.
• The inside of the fluorescent tube located within the LCD moni-
tor contains mercury. Please follow the bylaws or rules of your
local municipality to dispose of this tube properly.
Immediately unplug your monitor from the wall outlet and refer servic-
ing to qualified service personnel under the following conditions:
• When the power supply cord or plug is damaged.
• If liquid has been spilled or objects have fallen into the monitor.
• If the monitor has been exposed to rain or water.
• If the monitor has been dropped or the cabinet is damaged.

CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR
CAN REDUCE EYE, SHOULDERAND NECK FATIGUE. CHECKTHE
FOLLOWING WHEN YOU POSITION THE MONITOR:
• For optimum performance, allow 20 minutes for warm-up.
• Adjust the monitor height so that the top of the screen is at or
slightly below eye level. Your eyes should look slightly down-
ward when viewing the middle of the screen.
• Position your monitor no closer than 40 cm and no further away
than 70 cm from your eyes. The optimal distance is 53 cm for
the MultiSync LCD1525V monitor.
• Rest your eyes periodically by focusing on an object at least 6 m
away. Blink often.
• Position the monitor at a 90° angle to windows and other light
sources to minimize glare and reflections.Adjust the monitor tilt
so that ceiling lights do not reflect on your screen.
• If reflected light makes it hard for you to see your screen, use an
anti-glare filter.
• Clean the LCD monitor surface with a lint-free, non-abrasive
cloth. Avoid using any cleaning solution or glass cleaner!
• Adjust the monitor’s brightness and contrast controls to enhance
readability.
• Use a document holder placed close to the screen.
• Position whatever you are looking at most of the time (the screen
or reference material) directly in front of you to minimize turn-
ing your head while you are typing.
• Avoid displaying fixed patterns on the monitor for long periods
of time to avoid image persistence (after-image effects).
• Get regular eye checkups.

* Interpolated Resolutions: When resolutions are shown that are lower than the pixel count of
the LCD module, text may appear different. This is normal and necessary for all current flat
panel technologies when displaying non-native resolutions full screen. In flat panel technolo-
gies, each dot on the screen is actually one pixel, so to expand resolutions to full screen, an
interpolation of the resolution must be done.
** Active display area is dependent upon the signal timing.
Technical specifications are subject to change without notice.

Troubleshooting/Support E - 17
Problem
No picture
Power Button does
not respond
Image persistence
Check These Items
- The signal cable should be completely connected to
the display card/computer.
- The display card should be completely seated in its slot.
- Power button and computer power switch should be in
the ON position.
- Check to make sure that a supported mode has been
selected on the display card or system being used.
(Please consult display card or system manual to change
graphics mode.)
- Check the monitor and your display card with respect
to compatibility and recommended settings.
- Check the signal cable connector for bent or pushed-in
pins.
Unplug the power cord of the monitor from the AC
outlet to turn off and reset the monitor, or simultaneously
press the RESET and Power buttons.
Image persistence is when a “ghost” of an image remains
on the screen even after the monitor has been turned off.
Unlike CRT monitors, LCD monitors’image persistence
is not permanent. To alleviate image persistence, turn
the monitor off for as long as an image was displayed. If
an image was on the monitor for one hour and a “ghost”
of that image remains, the monitor should be turned off
for one hour to erase the image.
NOTE: As with all personal display devices, NEC
recommends using a screen saver at regular intervals
whenever the screen is idle.

Check These Items
- Signal cable should be completely attached to the
computer.
- Use the OSM ImageAdjust controls to focus and adjust
display by increasing or decreasing the Fine Control.
When the display mode is changed, the OSM Image
Adjust settings may need to be re-adjusted.
- Check the monitor and your display card with respect to
compatibility and recommended signal timings.
- If your text is garbled, change the video mode to non-
interlace and use 60 Hz refresh rate.
- Power Switch should be in the ON position and power
cord should be connected.
- Make certain the computer is not in a power-savingmode
(touch the keyboard or mouse).
- Use the OSM Image Adjust controls to increase or
decrease the H. Size.
- Check to make sure that a supported mode and signal
timing has been selected on the display card or system
being used. (Please consult display card or system manual
to change graphics mode or refresh rate.)
