installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be
required to correct the interference at his own expense.

DOC Compliance Notice

This digital apparatus does not exceed the Class A limits for
radio noise emissions from digital apparatus set out in the Radio
Interference Regulations of the Canadian Department of
Communications.

DOC Avis de Conformation

Le presént appareil numérique n’émet pas de bruits radio­électriques dépassant les limites applicables aux appareils
numériques de la Class A prescrites dans le Réglement sur le
brouillage radioélectrique édicté par le ministére des
Communications du Canada.

Introduction to the NEC LCD1280
True Color Monitor

The LCD1280 monitor provides superior display
performance, a reduced footprint and the flexibility and
adaptability required by today’s complex computing
environments.

The LCD1280 features a 13-inch (diagonal viewable
image size), active matrix, true-color, thin-film-transistor,
liquid crystal display to provide superior display perform­ance with a reduced footprint. Less than seven inches in
depth, the LCD1280 monitor is ideal for environments with
space and weight constraints that require superior image
quality. The LCD1280 also delivers the outstanding per-

formance necessary for today’s sophisticated Windows,
Macintosh, Silicon Graphics, Sun and other workstation
applications.

In addition to offering support for VGA graphics mode
(640 x 480), the LCD1280 supports WS high resolution
mode (1280 x 1024). The LCD1280 automatically detects
and changes between WS high resolution mode and VGA
graphics mode. The LCD1280 can display an infinite
number of colors in its high resolution mode.

Analog Interface

Because the LCD1280 accepts an analog input, a graphics
card with digital output is not required. The same graph­ics boar

d can be used to drive the LCD1280 or a standard
CRT monitor. The analog interface also provides the LCD
with its true-color capability. Unlike digital panels, the
LCD1280 is able to display a continuous spectrum of
“true” colors.

Reduced Footprint

The LCD1280 monitor offers nearly the same active
display size as a conventional 15-inch CRT (13.8” diagonal
viewable image size) at 40% of the depth and 30% of the
weight. With a depth of less than seven inches, the reduced
footprint of the LCD1280 provides the ideal solution for
applications requiring a large display and high resolution but
where space and weight are of particular con

cern.

Low Power Consumption

The LCD1280 has been designed with NEC’s IPM™ (Intelligent
Power Manager) System. When utilized with an Energy Star
system or video card, the LCD1280's IPM System is an innova­tive power saving utility that complies with both the EPA’s
Energy Star requirements and Europe’s NUTEK’s power man­agement requirements.

With a maximum power consumption of only 50 watts in
its on mode, the LCD1280 monitor consumes up to 50%
less power and emits less heat than conventional CRTs.
In its power saving mode, the LCD1280 consumes less
than 8 watts. All this translates into energy savings, envi­ronmental protection, reduced emissions and reduced air
conditioning costs of the work environment.

The LCD1280 monitor follows the Video Electronics Standard
Association (VESA) approved DPMS power-down signaling
method.

VESA’s Display Power Management Signaling (DPMS)
method which is endorsed by the EPA is the power-down
process a system should use to communicate to the monitor to
save power. Power-down functions can only be utilized with
an Energy Star system or video card which adheres to the
VESA DPMS standard. By using the monitor’s horizontal and
vertical SYNC signals, the monitor can be prompted into the

different IPM modes. The following is the description of the
LED indicator for the IPM power saving modes:

Mode LED Indicator Power Consumption

ON Green Typical: 45 watts
Stand By & Suspend Amber

Typical: Less than 8 watts

Power Switch, OFF No Light No Power Used

ErgoDesign™

The LCD1280 utilizes NEC’s ErgoDesign philosophy to
make the panel more comfortable and easy to use. The
panel’s power and brightness control are positioned within
easy reach, and the tilt base adjusts to each individual’s
preferred angle of vision. The LCD1280 monitor’s cabinet
design and aesthetics look good from all angles.

Reduced Emissions

Incorporating NEC’s own Reduced Magnetic Field™ tech­nology, the LCD1280 has minimal field emissions and
follows the strictest magnetic field, alternating electric field
and electro-static recommendations of the Swedish Board
for Technical Accreditation, or SWEDAC (previously
known as MPR, National Board for Measurement and
Testing). The LCD1280 conforms to SWEDAC MPR
1990:8 (MPR II) Testing Methods for Emissions. These
standards are the most restrictive guidelines in the world.
